At 4019.2Wh (314Ah engineering cells, ~3840Wh at the 300Ah nameplate) it is a serious RV house battery: one unit runs a 12V compressor fridge, water pump, LED lighting and device chargers for multiple days boondocking. It replaces roughly six 12V 100Ah lead-acid batteries in parallel on the same 12V bus, weighs 26 kg (57.3 lb) and fits a standard 54 cm (21.3 in) battery compartment.

On the 3840Wh nameplate, one GSIKE 300Ah can run that fridge alone for roughly 7-10 days, or a fridge plus lights, a fan and phone chargers (~150W average) for about 24 hours before a recharge. Solar topping during the day stretches that further. Keep the whole continuous load under 1280W; the 100A BMS handles fridge start-up inrush via the 400A one-second pulse.\"}}, {\"@type\": \"Question\", \"name\": \"What size 12V-to-120V inverter should I pair with it for US household outlets?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This is a 12V DC battery, not an inverter and not a 120V appliance itself. Pair it with a pure-sine 12V-to-120V inverter sized to your loads. Because the battery caps at 100A \/ 1280W DC continuous, a single 1000-1500W inverter is the practical ceiling from one pack; a 2000W inverter would overload the 100A BMS on sustained draw. Wire matched units in parallel to add current for larger inverters.

It is a stand-alone 12V DC deep-cycle storage battery.

The GSIKE 300Ah is listed at EUR 369.99. GSIKE's edge is capacity per dollar and ~6000 cycles; its honest trade-offs are a 100A (not 200A) BMS, no self-heating and a younger US brand presence.

Size panels to refill that each sunny day.\"}}, {\"@type\": \"Question\", \"name\": \"Can I parallel two of these for a marine house bank or boat?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes - parallel wiring on the 12V bus is the correct way to build a larger marine house bank: two matched units make 628Ah \/ ~8kWh, four make 1256Ah \/ ~16kWh, and the maximum is 4P4S = 16 units = 64.3kWh. Always parallel identical models matched within about one month of production; never mix new and worn cells. The steady 100A discharge and IP65 case suit a trolling motor and house loads, but it is a house\/deep-cycle pack, not a starter or traction battery, and it is not rated for immersion - mount it in a dry, ventilated locker.\"}}, {\"@type\": \"Question\", \"name\": \"What charger do I need in the US for 120V shore power or solar?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Use a LiFePO4-profile charger set to 14.4V +\/-0.2V (CC\/CV), recommended charge current 40A, with a 10V discharge cut-off. A 120V shore-power smart charger with a LiFePO4 setting, a DC-DC charger from the alternator, or a 12V solar charge controller (MPPT) with a 14.4V absorption voltage all work. Do not use a legacy lead-acid charger that only floats at 13.5-13.8V - it will never fully charge these cells.\"}}, {\"@type\": \"Question\", \"name\": \"What is the US shipping, return window and warranty?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Shipping is free within the United States: 1-3 days handling plus 3-7 days transit, with a 30-day return window from delivery. The pack weighs 26 kg net (27 kg gross \/ 59.5 lb), so plan a two-person lift. Warranty is 3 years against a roughly 10-year design life. The store currently lists this SKU in EUR 369.99 - confirm with the merchant whether the US site should display USD at checkout before ordering.\"}}]}\u003c\/script\u003e\n\u003c\/p\u003e\n\u003c\/main\u003e\n\u003cdiv class=\"gsikekeywords\"\u003e\nEtiquetas: bateria LiFePO4 de 12 V e 300 Ah, bateria de lítio de 314 Ah para autocaravana, bateria LiFePO4 de 12,8 V e 300 Ah, bateria de lítio de 4 kWh e 12 V, bateria de lítio grande de 12 V, bateria LiFePO4 de 4019 Wh, bateria de 12 V e 300 Ah para autocaravana, bateria de lítio de 12 V para energia solar numa cabana autónoma, bateria de lítio de ciclo profundo de 12 V e 300 Ah, bateria LiFePO4 de 12 V e 300 Ah com BMS, bateria GSIKE de 12,8 V e 300 Ah\u003cbr\u003e\nbateria LiFePO4 de 12 V e 300 Ah, bateria de lítio de 314 Ah para autocaravana, bateria de lítio de 12 V para energia solar numa cabana autónoma, bateria de lítio de 4 kWh e 12 V, bateria de lítio grande de 12 V, bateria de lítio de 300 Ah e 12 V para autocaravana, bateria LiFePO4 de 4019 Wh, bateria de 12 V para inversor de 120 V para reserva doméstica, banco de baterias marítimo de lítio de 12 V, bateria para frigorífico de compressor de 12 V, preço da bateria GSIKE de 12,8 V e 300 Ah, melhor bateria LiFePO4 de 12 V e 300 Ah nos EUA\u003cbr\u003e\ncomprar bateria LiFePO4 de 12 V e 300 Ah nos EUA, bateria de lítio de 12 V e 300 Ah para autocaravana ou carrinha camper, LiFePO4 de 300 Ah para energia solar numa cabana autónoma, bateria solar de 12 V e 300 Ah para reserva doméstica, banco de baterias marítimo de lítio de 12 V e 300 Ah, bateria de 12 V para inversor de 12o V para reserva doméstica, bateria de 300 Ah para frigorífico de compressor de 12 V, LiFePO4 de 12 V e 300 Ah com envio gratuito nos EUA, LiFePO4 de 12 V e 300 Ah com devoluções em 30 dias e garantia, bateria LiFePO4 barata de 12 V e 300 Ah nos EUA, melhor bateria de lítio autónoma de 4 kWh nos EUA, preço da bateria GSIKE de 12,8 V e 300 Ah\u003cbr\u003e\nbateria para autocaravana de 100 Ah vs 200 Ah vs 300 Ah, quantos kWh tem uma bateria de 12 V e 300 Ah, durante quanto tempo uma bateria de 300 Ah alimenta um frigorífico de 12 V, que tamanho de bateria para energia solar numa cabana autónoma, quantos dias de autonomia oferece uma bateria de 30o Ah, baterias LiFePO4 de 12 V em série vs em paralelo, como carregar uma bateria LiFePO4 de 300 Ah, que tamanho de inversor para uma bateria de 12 V e 300 Ah, quanto pesa uma bateria LiFePO4 de 300 Ah, quantas baterias de chumbo-ácido substitui uma LiFePO4 de 300 Ah, posso usar uma LiFePO4 de 300 Ah para um motor de pesca\u003cbr\u003e\nmelhor bateria LiFePO4 de 12 V e 300 Ah nos EUA em 2026, GSIKE vs LiTime 12 V 300 Ah LiFePO4, GSIKE vs Renogy 12 V 300 Ah LiFePO4, GSIKE vs bateria Battle Born de 12 V, LiTime 300 Ah vs Renogy Core 300 Ah, BMS de 100 A vs 200 A numa bateria de 12 V e 300 Ah, Redodo 12 V 300 Ah LiFePO4 vs GSIKE, análise da Power Queen 12 V 300 Ah LiFePO4, bateria LiFePO4 barata de 12 V e 300 Ah nos EUA, GSIKE 100 Ah vs 300 Ah: qual escolher\u003cbr\u003e\n\u003c\/div\u003e","brand":"GSIKE Power","offers":[{"title":"Default Title","offer_id":48085969895585,"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\/pt\/products\/gsike-12-8v-300ah-lifepo4-battery-4019-2wh-100a-bms-gsike-us","provider":"Gsike","version":"1.0","type":"link"}
