Its eight 3.2V cells are wired **8S1P** (8 in series, 1 parallel string) to give **25.6V nominal**, the "24V class" figure motorhomes and boats use. Keep two numbers straight: it holds **2560Wh** (25.6V × 100Ah) and its **2560W** DC ceiling (25.6V × 100A) is what lets it run an 1800W appliance — about double the 1280W of a 12V 100Ah. To charge it you need a **25.6V / 28.8V LiFePO4 charger**; to run mains appliances you add a **separate 24V-rated inverter**. Do not mix it with 12V batteries on the same bus. **Specification note — read before you size your loads or fit it.** (a) **Headline size and weight:** the product-specific diagrams give **520 × 250 × 320 mm** (L×W×H over the terminals) and **21.15 kg** net (~46.6 lb). (b) **Pulse / peak current:** use **400A for one second** for startup inrush (not continuous). Treat 400A/1s as the planning figure before wiring any high-startup load. ## Manual specifications Parameter Value Chemistry / assembly LiFePO4 (LFP), **8S1P** — 8 × 3.2V cells in series, 1 parallel string Nominal voltage / class **25.6 V** nominal (the "24V class" bus) Rated capacity / energy **100 Ah / 2560 Wh** (25.6V × 100Ah) Continuous current / power **100 A charge / 100 A discharge** = **2560 W** DC ceiling Pulse / peak **400 A for 1 second only** (startup inrush; not continuous) BMS **100 A BMS** — over-charge, over-discharge, over-current, over-temperature and short-circuit protection (OEM / Easun module) Cycle life **\>6000 cycles at 100% DoD** @25°C / 0.5C (more cycles at 80% DoD) Charge settings **CC/CV**; charge voltage **28.8–29.2 V** (28.8V ±0.4V); use a **25.6V LiFePO4 charger, 20–100 A** Discharge cut-off **20 V ±0.5 V** end-of-discharge Internal resistance ≤20 mΩ Expansion **4P4S = 16 units = 40.96 kWh** (4S = 102.4V, 4P = 400Ah); 2S = 51.2V / 5.12kWh Terminals **M8 bolts** (8 mm bolt / 12 mm nut) Housing / ingress ABS housing, **IP65**; CE, RoHS, UN38.3 certified Weight / size (headline) Net **21.15 kg** (~46.6 lb); **520 × 250 × 320 mm** (L×W×H over terminals) Warranty / design life **3-year warranty**; ~10-year design life Price / stock **€279.99 EUR** sale, struck from **€420.00** (33.3% off); In stock, new Delivery / returns Free shipping to European countries (1–3 days handling + 2–7 days transit) · 30-day returns ## Pick the right GSIKE voltage — this 25.6V 100Ah vs the 12.8V 100Ah and 12.8V 300Ah siblings Same GSIKE line, three SKUs. This page sells the **25.6V 100Ah** (the 24V-class pack). The table below compares it against the two 12V-class siblings so you can choose by voltage and use case. The decisive difference: at 25.6V the same 100A BMS delivers **2560W** — double the 1280W of the 12V 100Ah — while pulling half the current for the same watts.

Doubling the voltage from 12.8V to 25.6V with the same 100A BMS doubles the DC ceiling to 2560W, which is why this pack — not the 12V 100Ah — can run an 1800W load. It also halves the cable current for the same watts, so runs cooler with thinner cables. Full reasoning is in the linked voltage guide below. ## Lead-acid replacement — two 12V 100Ah lead-acid batteries in series (24V) This 25.6V pack is the direct replacement for **two 12V 100Ah lead-acid batteries wired IN SERIES to make 24V**. Because LiFePO4 safely delivers close to its full capacity while flooded lead-acid is limited to about 50% depth of discharge, one GSIKE 25.6V 100Ah gives roughly **2.1× the usable energy** of that lead-acid pair. Metric One GSIKE 25.6V 100Ah LiFePO4 Two 12V 100Ah flooded lead-acid (in series = 24V) Nominal energy **2560 Wh** ~2400 Wh nameplate (2 × 1200 Wh) Usable energy (DoD) **~2560 Wh** at ~100% usable DoD **~1200 Wh** at ~50% DoD for longevity Usable multiple **~2.1× more usable energy than the lead-acid pair** Cycle life **\>6000 cycles @100% DoD** ~500 cycles Weight **21.15 kg net** ~55–60 kg for the pair Maintenance None (no watering, no equalisation) Watering / venting / equalisation **Mixing warning:** this is a single 24V-class (25.6V) bus. It replaces the two-lead-acid _series_ pair — do not wire it in parallel with 12V packs, and do not present it as a 12V parallel-bank replacement. When you later add units, match identical models within about one month of age / charge history. ## Expected run-time by load (2560 Wh ÷ load) Ideal DC runtimes at the 2560Wh nameplate, before derating. **Keep every continuous load at or below the 2560W ceiling.** The 1800W row is valid because 1800 < 2560 — that is the whole point of the 24V class over a 12V 100Ah (which tops out at 1280W and could not run it). When running through a separate 24V inverter, derate by about 90–95% efficiency and leave depth-of-discharge headroom. Load Example use Runtime (2560 Wh nameplate) 50 W LED lights + router + phone charging **51.2 h** 100 W Lights + fan + laptop + small pump **25.6 h** 120 W Compressor fridge running steady **21.33 h** 300 W Fridge + TV + fan + lighting **8.53 h** 500 W Fridge + small kitchen loads **5.12 h** 800 W Fridge + microwave cycles + chargers **3.2 h** 1000 W Higher leisure / small appliance load **2.56 h** 1800 W Larger appliance (valid: 1800 < 2560 ceiling) **1.42 h** 2560 W Full manual DC ceiling **1.0 h** ## Charge settings & operating temperatures Item Specification Charge method **CC/CV** (constant current, constant voltage) Charge voltage **28.8–29.2 V** (28.8V ±0.4V) — a dedicated 25.6V LiFePO4 profile; **a 12V charger (~14.6V) will not finish the job** Recommended charger **25.6V LiFePO4 charger, 20–100 A**; the BMS allows up to 100 A continuous charge Discharge cut-off **20 V ±0.5 V** end-of-discharge cut-off Internal resistance ≤20 mΩ Charge temperature **0 °C to 55 °C**; **do not charge below 0 °C** (no self-heating element) Discharge temperature **−20 °C to 55 °C** Storage temperature **−20 °C to 45 °C** (within a month); 0–35 °C (within a year); store at ~50% charge ## Expansion — 2S to 51.2V, 4P4S up to 40.96 kWh The battery supports parallel and series building. **Two units in series (2S)** give **51.2V / 5.12kWh** — the common 48V-class setup. **4P4S** = four in parallel × four in series: **16 units total = 40.96 kWh** (4S raises the voltage to **102.4V**; 4P raises capacity to **400Ah**; 102.4V × 400Ah = 40,960Wh). Configuration Voltage Capacity Energy Units 1P1S (single) 25.6 V 100 Ah 2.56 kWh 1 **2P1S** (parallel) 25.6 V 200 Ah 5.12 kWh 2 **2S** (series, common 48V) **51.2 V** 100 Ah **5.12 kWh** 2 4P1S 25.6 V 400 Ah 10.24 kWh 4 **4P4S (max)** **102.4 V** **400 Ah** **40.96 kWh** **16** **Matching rule:** when wiring units in series or parallel, use batteries that are identical in model and matched within about one month of production / charge history. Do not mix new and heavily-used units in one bank, and keep the whole bank on the 28.8V charge profile with the 20V cut-off. ## Pros & cons ### Pros - **2560Wh at ~100% usable DoD with a 2560W DC ceiling** — the 24V class runs an **1800W appliance**, which a 12V 100Ah (1280W) cannot. Same 100A BMS, double the voltage, half the cable current. - **\>6000 cycles at 100% DoD** and ~10-year design life with zero maintenance — roughly 2.1× the usable energy of two 12V 100Ah lead-acid in series, at 21.15 kg versus ~55–60 kg. - **€279.99 struck from €420.00** — the cheapest verified single-unit branded EU-storefront 24V 100Ah pack: LiTime €499.99, Renogy self-heating €469.99, Power Queen €479.99, Redodo €439.99 — with free EU shipping and 30-day returns. - **Expandable:** 2S to 51.2V / 5.12kWh (common 48V) and 4P4S to 16 units / 40.96kWh, so one starter unit grows into a larger bank. - **IP65 ABS case, M8 terminals, CE/RoHS/UN38.3** — at home in a damp motorhome locker, caravan bay, boat compartment or workshop. - Real buyer rating **4.9 / 5 from 14 reviews**, praising the higher voltage / lower cable loss, quick solar charging and the Easun BMS protection. ### Cons - **Needs 24V-class gear.** You must pair it with a **24V / 25.6V inverter** and a **28.8V LiFePO4 charger** — a 12V inverter and a 12V (~14.6V) charger will not work on this pack. - **21.15 kg is heavier and larger than a 12V 100Ah** (~9.8 kg). Plan a two-person lift into a locker or boat compartment. - **Do not mix with 12V batteries directly** — it is a single 24V bus; never parallel it with 12V packs. - **Match identical units within ~1 month** of production / charge history for series or parallel; never mix new and worn cells in one bank. - **No cold charging below 0°C** (charge window 0–55°C; discharge works down to −20°C). Unlike Renogy self-heating or LiTime low-temp rivals, this pack has no heater and no app/Bluetooth monitoring. - **Not for golf carts** — this is a 24V leisure / deep-cycle pack, not a traction battery for golf-cart drive current. ## Where this battery fits — real European use cases ![Cozy modern German motorhome living interior, a matte-black LiFePO4 battery box about 52 cm long on a light wooden bench seat, two silver M8 terminals, folded linen cushion, white curtains, green alpine meadow through the window](https://aka.doubaocdn.com/s/1QFpaLtjCe) ### Motorhome living area On a wooden bench base it runs the fridge, water pump and chargers through the evening — the 2560W ceiling covers a compact 24V leisure load. ![Open under-seat locker bay of a modern British touring caravan, a matte-black LiFePO4 battery box about 52 cm long strapped in with a grey hold-down strap, two silver M8 terminals, neat red and black cables](https://aka.doubaocdn.com/s/7Wd9NW9mxm) ### Touring caravan locker Strapped into the under-seat bay, the 52 cm case fits an existing compartment and powers a weekend away from hook-up. ![Interior of a small rustic Nordic log cabin at dusk, a matte-black LiFePO4 battery box about 52 cm long on a heavy pine shelf, two silver M8 terminals, a warm pendant lamp, dark forest through small frosted windows](https://aka.doubaocdn.com/s/K5faKvR7v5) ### Off-grid log cabin A remote cabin relies on it for warm light and device power after the panels stop generating, across cloudy days. ![A tidy Dutch home garage workshop, a matte-black LiFePO4 battery box about 52 cm long on a heavy wooden workbench connected by thick red and black charging cables, hanging tools softly blurred](https://aka.doubaocdn.com/s/UINybaFixL) ### Home workshop On a workbench it charges from the 28.8V source and supplies bench lighting, pumps and chargers — the 20V cut-off protects the cells. ![Tidy European home utility room for solar self-consumption, a matte-black LiFePO4 battery box about 52 cm long on a low steel rack next to a plain grey metal switch cabinet, neat red and black cables](https://aka.doubaocdn.com/s/kcSUVdo4LN) ### Solar self-consumption Mounted on a rack beside the switchgear, it stores daytime solar and covers the evening load, expandable later in parallel. ![Open built-in storage locker of a small blue-and-white fishing boat on a calm Dutch lake, a matte-black LiFePO4 trolling battery box about 52 cm long fitted inside, two silver M8 terminals, an electric trolling motor softly out of focus at the stern](https://aka.doubaocdn.com/s/InVVbWzhpl) ### Fishing boat / trolling The steady 100A discharge gives a trolling motor smooth thrust without sag — buyers report a full day on one charge. ![A tidy European home electrical cabinet room, a matte-black LiFePO4 battery box about 52 cm long with two silver M8 terminals connected by a thick black cable to a compact sealed plain dark-grey inverter box on the right with a blank closed front](https://aka.doubaocdn.com/s/PFuIg27QUk) ### Cabinet with a separate inverter Here the battery sits beside a separate 24V-class inverter — remember the pack itself is a battery, not an inverter, and must be matched to 24V gear. ![A tidy garage, two identical matte-black LiFePO4 battery boxes each about 52 cm long standing side by side on a heavy wooden rack, two silver M8 terminals on each, a thick red interconnector cable wiring the two in series](https://aka.doubaocdn.com/s/eOG4juxMKZ) ### Two units in series (2S) Wire two of these in series to reach 51.2V / 5.12kWh — the common 48V setup — matching identical units within a month of age. ## Shipping & returns Policy point Detail Price €279.99 EUR sale, struck from **€420.00** (33.3% off) · In stock, new condition Free delivery to European countries Handling / transit Handling 1–3 days + transit 2–7 days, shipping rate EUR 0 Returns 30-day return window from delivery, by post, in original condition and packaging Return cost Return shipping is handled by the merchant; original import duties and taxes are non-refundable ## Frequently asked questions Why choose a 24V (25.6V) battery over a 12V 100Ah — what does the higher voltage actually buy me? With the same 100A BMS, doubling the voltage from 12.8V to 25.6V doubles the continuous DC ceiling: 12.8V×100A = 1280W, while 25.6V×100A = 2560W. That is why this pack can run an 1800W appliance (1800 < 2560), whereas a 12V 100Ah tops out at 1280W and cannot. For the same wattage the current is halved, so the runs cooler and you can use thinner cables with less voltage drop. You pay about €120 more than the 12V 100Ah for that power headroom and the 2.56kWh of energy. Can I use my existing 12V LiFePO4 charger on this 25.6V battery? No. This is an 8S1P 25.6V pack that needs a 28.8–29.2V CC/CV charge profile (28.8V ±0.4V), with a 20V cut-off. A standard 12V charger finishes at roughly 14.2–14.6V — less than half of the required charge voltage — so it will never fully charge this battery and could leave the cells chronically under-charged. Use a dedicated 25.6V LiFePO4 charger rated 20–100A. Does this 25.6V battery really replace two 12V lead-acid batteries in series? Yes. This pack is the direct replacement for two 12V 100Ah lead-acid batteries wired in series to make 24V. Those two lead-acid cells give about 1200 usable Wh at a 50% depth of discharge, while this LiFePO4 delivers the full ~2560 usable Wh near 100% DoD — roughly 2.1× the usable energy, in one 21.15kg unit instead of ~55–60kg of lead. Keep it on the 24V bus; do not parallel it with 12V packs. How long will it run an 1800W load — is 1800W even valid on this battery? It is valid: 1800W is below the 2560W DC ceiling, so it runs continuously rather than triggering the BMS. Dividing 2560Wh by 1800W gives about 1.42 hours. On the runtime table you also get 50W→51.2h, 300W→8.53h, 1000W→2.56h and, at the full 2560W ceiling, about 1.0h. Through a separate 24V inverter, derate by 90–95% efficiency and leave DoD headroom. Can I mix this 24V battery with my existing 12V batteries? No. This is a single 24V-class (25.6V) bus — do not wire it in parallel with 12V packs, and do not treat it as a 12V parallel-bank replacement. When you expand, add units that are identical in model and matched within about one month of production / charge history. Mixing new and heavily-used cells in one bank causes imbalance and shortens life; keep the whole bank on the 28.8V charge profile with the 20V cut-off. How do I get to 48V — do two of these in series give me a 48V system? Two units in series (2S) give 51.2V and 5.12kWh — that is the common "48V" nominal setup, and it is the usual route if you need a 48V-class inverter. At the top end, 4P4S (four parallel × four series) = 16 units for 102.4V and 400Ah, i.e. 40.96kWh. Always match identical units within about a month before wiring them in series or parallel. What charger, cables and terminals do I actually need? A 25.6V LiFePO4 charger delivering 28.8–29.2V CC/CV at 20–100A, with the battery's 20V cut-off respected. The terminals are M8 bolts (8mm bolt / 12mm nut), so fit battery lugs that match an M8 stud and size the cables for up to 100A continuous at 25.6V — thicker short cables keep voltage loss low. Because this is a 24V pack, pair it with a 24V-rated inverter, not a 12V unit. Can it charge in winter, below freezing? No. The charge window is 0°C to 55°C — do not charge below 0°C, because charging a LiFePO4 cell when it is cold can cause lithium plating and damage. It will still discharge down to −20°C. Unlike some rivals with a self-heating element or low-temperature charge cut-off, this pack has no heater and no app, so mount it where the space stays above freezing in winter. The diagrams show 520×250×320mm and 21.15kg — why do other spec sheets list different numbers? The product-specific diagrams we use as the headline give 520×250×320mm over the terminals and 21.15kg net. Other documents list slightly different case and box figures, most likely the bare ABS case versus the packaged / shipping dimensions rather than a second product. These alternate numbers are collected in the specification note on this page, and you should confirm the true case and box dimensions with the merchant before designing a battery bay. What about the 400A pulse, the warranty, the price and the returns? The 400A figure is a one-second pulse for startup inrush, not a continuous rating; one excluded marketing graphic labels a higher one-second peak, which we have not used — confirm the true peak with the merchant. The pack is priced at €279.99 struck from €420.00, in stock and new, with a 3-year warranty against a ~10-year design life.
