Duplicar a tensão de 12.8V para 25.6V com o mesmo BMS de 100A duplica o limite de corrente contínua para 2560W, e é por isso que este conjunto — e não o de 12V 100Ah — pode alimentar uma carga de 1800W.

em corrente contínua: 12,8 V×100 A = 1280 W, enquanto 25,6 V×100 A = 2560 W. É por isso que esta bateria pode alimentar um aparelho de 1800 W (1800 \u0026lt; 2560), enquanto uma bateria de 12 V 100 Ah tem um limite de 1280 W e não consegue. Para a mesma potência, a corrente é reduzida para metade, pelo que o sistema aquece menos e pode utilizar cabos mais finos, com menor queda de tensão.

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.\"}}, {\"@type\": \"Question\", \"name\": \"How long will it run an 1800W load — is 1800W even valid on this battery?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.\"}}, {\"@type\": \"Question\", \"name\": \"Can I mix this 24V battery with my existing 12V batteries?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.\"}}, {\"@type\": \"Question\", \"name\": \"How do I get to 48V — do two of these in series give me a 48V system?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.\"}}, {\"@type\": \"Question\", \"name\": \"What charger, cables and terminals do I actually need?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.\"}}, {\"@type\": \"Question\", \"name\": \"Can it charge in winter, below freezing?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.\"}}, {\"@type\": \"Question\", \"name\": \"The diagrams show 520×250×320mm and 21.15kg — why do other spec sheets list different numbers?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.\"}}, {\"@type\": \"Question\", \"name\": \"What about the 400A pulse, the warranty, the price and the returns?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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. Shipping is free to 15 European countries (1–3 days handling plus 2–7 days transit), with 30-day returns by post.\"}}]}\u003c\/script\u003e\n\u003c\/p\u003e\n\u003c\/main\u003e\n\u003cdiv class=\"gsikekeywords\"\u003e\nEtiquetas: bateria LiFePO4 24 V 100 Ah, bateria LiFePO4 25,6 V 100 Ah, bateria de lítio de 2560 Wh, bateria de lazer de 24 V, bateria de lítio 24 V 100 Ah para sistema solar de autocaravana, bateria de lítio 24 V 2560 W, bateria GSIKE 25,6 V 100 Ah\u003cbr\u003e\nbateria LiFePO4 24 V 100 Ah, bateria LiFePO4 25,6 V 100 Ah, bateria de lítio de 2560 Wh, bateria de lazer de 24 V, bateria de lítio 24 V 100 Ah para sistema solar de autocaravana, bateria de lítio 24 V 2560 W, bateria GSIKE 25,6 V 100 Ah, comprar bateria LiFePO4 24 V 100 Ah na Europa, LiFePO4 24 V 100 Ah por menos de 280 €, LiFePO4 24 V 100 Ah em armazém na UE, bateria 24 V 100 Ah para barco e motor elétrico de pesca, comparação de preços de baterias de lítio de 2560 Wh na Europa\u003cbr\u003e\ncomprar bateria LiFePO4 24 V 100 Ah na Europa, LiFePO4 24 V 100 Ah por menos de 280 €, LiFePO4 24 V 100 Ah em armazém na UE, bateria de lítio de 24 V para autocaravana, LiFePO4 24 V 100 Ah para sistema solar numa cabana autónoma, preço da bateria GSIKE 25,6 V 100 Ah, bateria de lítio 24 V 100 Ah com envio grátis na Europa, bateria de lazer 24 V no Reino Unido e na Europa, bateria 24 V 100 Ah para barco e motor elétrico de pesca, LiFePO4 24 V com devoluções em 30 dias e garantia de 3 anos, LiFePO4 24 V 100 Ah disponível em stock na Europa, entrega em 2-7 dias, comparação de preços de baterias de lítio de 2560 Wh na Europa\u003cbr\u003e\nbateria LiFePO4 12 V vs. 24 V vs. 48 V, queda de tensão da bateria 24 V vs. 12 V e secção do cabo, o que pode alimentar uma bateria 24 V 100 Ah, tensão de carga da LiFePO4 24 V: 28,8 V, substituição de duas baterias de chumbo-ácido de 12 V em série por uma de 24 V, baterias LiFePO4 de 24 V em série vs. em paralelo, duas baterias de 24 V em série: 51,2 V ou 48 V, banco de baterias LiFePO4 24 V 4P4S de 40 kWh, durante quanto tempo funciona um inversor de 1800 W com uma bateria de 24 V 100 Ah, tensão de 24 V vs. 48 V para energia solar autónoma, que potência deve ter um inversor de 24 V para uma bateria de 2560 Wh, como ligar duas baterias de 12 V em série para obter 24 V\u003cbr\u003e\nmelhor bateria LiFePO4 24 V 100 Ah na Europa 2026, GSIKE vs. LiTime 24 V 100 Ah LiFePO4, GSIKE vs. Renogy 24 V 100 Ah LiFePO4, Redodo 24 V 100 Ah LiFePO4 vs. GSIKE, análise da Power Queen 24 V 100 Ah LiFePO4, Eco-Worthy 24 V 100 Ah LiFePO4 vs. GSIKE, Easun 24 V 100 Ah LiFePO4 vs. GSIKE, LiTime 24 V 100 Ah vs. Renogy 24 V 100 Ah LiFePO4, bateria LiFePO4 24 V 100 Ah barata na Europa, LiFePO4 24 V 100 Ah por menos de 350 € na Europa, GSIKE 12 V 100 Ah vs. 25,6 V 100 Ah: qual escolher, LiFePO4 24 V 100 Ah com Bluetooth e proteção contra baixas temperaturas vs. GSIKE\n\u003c\/div\u003e","brand":"GSIKE Power","offers":[{"title":"Default Title","offer_id":46473906913441,"sku":"GSK-25.6V-100AH","price":279.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/3042\/7041\/files\/25.6v-100ah.webp?v=1781229409","url":"https:\/\/gesike.com\/pt-pt\/products\/gsike-25-6v-100ah-lithium-energy-storage-battery-for-solar-power-system","provider":"Gsike","version":"1.0","type":"link"}
