The \\\"300Ah\\\" tier name × 12.8V = ~3840Wh, the figure printed on marketing and runtime graphics. Both describe the same pack. Spec tables on this page use the conservative manual 314Ah \/ 4019.2Wh and the 3840Wh nameplate for run-time; we never conflate this 4kWh pack with the smaller 100Ah sibling.\"}}, {\"@type\": \"Question\", \"name\": \"What is the largest continuous load I can run — can I pull more than 1280W?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The conservative manual ceiling is 1280W continuous (12.8V × 100A charge and discharge), with a 400A one-second pulse for startup inrush. Plan every steady load at or below 1280W. GSIKE's marketing graphics for this pack show a higher BMS rating and a larger appliance; treat 1280W as your planning number and confirm the true BMS rating with the merchant before wiring anything above it (see the specification note). Parallel batteries add current — a single 300Ah does not raise the 1280W ceiling.\"}}, {\"@type\": \"Question\", \"name\": \"Does one 300Ah battery really replace six lead-acid batteries?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Roughly, on the same 12V bus. One GSIKE 300Ah delivers ~3818–4019 usable Wh at ~95–100% depth of discharge, whereas a 12V 100Ah flooded lead-acid gives only ~504 usable Wh at ~42% DoD. So one GSIKE replaces about six 12V 100Ah lead-acid batteries wired IN PARALLEL on the 12V bus. Never wire them in series to make 24V — that is a different system.\"}}, {\"@type\": \"Question\", \"name\": \"Why does the 300Ah still cap at 1280W even though it holds about 3× the energy of the 100Ah?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Because energy (Wh) and power (W) are two different things. This 12V GSIKE family uses the same 100A BMS whether the pack holds 100Ah or 314Ah, so at 12.8V the continuous ceiling is 100A × 12.8V = 1280W on every single unit. The extra cells only lengthen run-time (4019.2Wh vs ~1.28kWh) — they do not raise the one-pack power ceiling. To pull more watts continuously, wire matched units in parallel (current adds while the voltage stays 12.8V) or build a higher-voltage series bank; until then, never plan a steady load above 1280W on a single 300Ah.\"}}, {\"@type\": \"Question\", \"name\": \"How long will it run my fridge, lights and appliances?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"At the 3840Wh nameplate divided by the load: 100W → 38.4h, 300W → 12.8h, 500W → 7.68h, 800W → 4.8h and 1000W → 3.84h. Keep every continuous load at or below the 1280W ceiling; at the full ceiling the bank lasts ~3.0–3.14h. When running through a separate 12V inverter, derate by about 90–95% efficiency and leave depth-of-discharge headroom.\"}}, {\"@type\": \"Question\", \"name\": \"How do I expand the bank — series or parallel, and how far?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The maximum configuration is 4P4S: four in parallel times four in series = 16 units, giving 51.2V and 1256Ah for 64.3kWh. When building a bank, use units that are identical in model and matched within about one month of production \/ charge history; do not mix new and heavily-used units, and keep the whole bank on the 14.4V charge profile with the 10V cut-off.\"}}, {\"@type\": \"Question\", \"name\": \"The box reads 300Ah but the manual lists 314Ah \/ 4019.2Wh — which rating should I trust?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Both, for different jobs. The inside cells are engineering-rated 314Ah (12.8V × 314Ah = 4019.2Wh); GSIKE sells this in the conservative \\\"300Ah\\\" tier, whose nameplate is 12.8V × 300Ah ≈ 3840Wh — the figure on the marketing and runtime graphics. Use 314Ah \/ 4019.2Wh for spec comparisons and the 3840Wh nameplate to estimate run-time. The ~180Wh gap is tier rounding, not a second battery, and it does not change the 100A BMS, the 1280W ceiling or the 6000-cycle rating.\"}}, {\"@type\": \"Question\", \"name\": \"How heavy is the 300Ah and how should I move or mount it?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It weighs 26kg net (27kg gross) — genuinely heavy, so plan a two-person lift and use the integrated handles when tilting it into a motorhome locker or boat compartment. Bolt it down through the base with the M8 terminals using the supplied hardware, keep it upright, leave ventilation around the ABS case and run the thick 12V cables short.

The price is €369.99 EUR, in stock and new. Shipping is free to 15 European countries (1–3 days handling plus 2–7 days transit), with 30-day returns by post. The warranty is 3 years against a ~10-year design life, so the covered period is shorter than the expected service life at light use.\"}}]}\u003c\/script\u003e\n\u003c\/p\u003e\n\u003c\/main\u003e\n\u003cdiv class=\"gsikekeywords\"\u003e\nOznake: 12 V 300 Ah LiFePO4 baterija, litijska baterija od 300 Ah, 12,8 V 300 Ah LiFePO4 baterija, litijska baterija od 4 kWh i 12 V, velika litijska baterija od 12 V, pomoćna baterija od 300 Ah za slobodno vrijeme, LiFePO4 baterija od 4019 Wh\u003cbr\u003e\n12 V 300 Ah LiFePO4 baterija, litijska baterija od 300 Ah, 12,8 V 300 Ah LiFePO4 baterija, litijska baterija od 4 kWh i 12 V, velika litijska baterija od 12 V, pomoćna baterija od 300 Ah za slobodno vrijeme, LiFePO4 baterija od 4019 Wh, kupite 12 V 300 Ah LiFePO4 bateriju u Europi, 12 V 300 Ah LiFePO4 baterija ispod 370 EUR, 12 V 300 Ah LiFePO4 iz skladišta u EU-u, cijena baterije GSIKE 12,8 V 300 Ah, usporedba cijena litijskih baterija od 4 kWh i 12 V u Europi\u003cbr\u003e\nkupite 12 V 300 Ah LiFePO4 bateriju u Europi, 12 V 300 Ah LiFePO4 baterija ispod 370 EUR, 12 V 300 Ah LiFePO4 iz skladišta u EU-u, litijska baterija od 300 Ah za kamp-kućicu, baterija LiFePO4 od 300 Ah za solarni sustav u vikendici izvan mreže, cijena baterije GSIKE 12,8 V 300 Ah, besplatna dostava litijske baterije od 12 V i 300 Ah u Europi, pomoćna baterija od 300 Ah za slobodno vrijeme u Ujedinjenoj Kraljevini i Europi, solarna baterija od 12 V i 300 Ah za pohranu energije u kućanstvu, 12 V 300 Ah LiFePO4 s jamstvom i rokom povrata od 30 dana, 12 V 300 Ah LiFePO4 na zalihi u Europi, dostava za 2-7 dana, usporedba cijena litijskih baterija od 4 kWh i 12 V u Europi\u003cbr\u003e\nlitijska baterija od 100 Ah vs 300 Ah, koliko kWh ima baterija od 300 Ah, koliko će dana autonomije pružiti baterija od 300 Ah, koliko će dugo baterija LiFePO4 od 300 Ah napajati uređaje, koja veličina baterije za solarnu energiju u kući izvan mreže, 12 V LiFePO4 baterije serijski vs paralelno, baterijski sklop LiFePO4 4p4s od 64 kWh, koliko teži baterija LiFePO4 od 300 Ah, kako napuniti bateriju LiFePO4 od 300 Ah, 300 Ah vs 200 Ah LiFePO4: koja mi je potrebna, koliko olovnih baterija može zamijeniti baterija LiFePO4 od 300 Ah, kalkulator vremena rada baterije od 12 V i 300 Ah\u003cbr\u003e\nnajbolja 12 V 300 Ah LiFePO4 baterija u Europi 2026., GSIKE vs LiTime 12 V 300 Ah LiFePO4, GSIKE vs Renogy 12 V 300 Ah LiFePO4, Redodo 12 V 300 Ah LiFePO4 vs GSIKE, recenzija Power Queen 12 V 300 Ah LiFePO4, Eco-Worthy 12 V 300 Ah LiFePO4 vs GSIKE, Easun 12 V 300 Ah LiFePO4 vs GSIKE, recenzija Datouboss 12 V 300 Ah LiFePO4, GSIKE 100 Ah vs 300 Ah: koju bateriju odabrati, LiTime 300 Ah vs Renogy Core 300 Ah LiFePO4, jeftina 12 V 300 Ah LiFePO4 baterija u Europi, 12 V 300 Ah LiFePO4 baterija ispod 400 EUR u Europi\n\u003c\/div\u003e","brand":"GSIKE Power","offers":[{"title":"Default Title","offer_id":46473904324769,"sku":"GSK-12.8V-300AH","price":423.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/3042\/7041\/files\/12.8v-300ah.webp?v=1781229409","url":"https:\/\/gesike.com\/hr\/products\/gsike-12-8v-300ah-lithium-energy-storage-battery-for-solar-power-system","provider":"Gsike","version":"1.0","type":"link"}
