O nome do escalão «300Ah» × 12,8V = ~3840Wh, o valor indicado nas imagens de marketing e de autonomia. Ambos descrevem o mesmo conjunto. As tabelas de especificações desta página usam os valores conservadores do manual, 314Ah \/ 4019,2Wh, e a capacidade nominal de 3840Wh para calcular a autonomia; nunca confundimos este conjunto de 4kWh com o modelo mais pequeno de 100Ah.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eQual é a maior carga contínua que posso utilizar — posso ultrapassar 1280W?\u003c\/summary\u003e\n\u003cp\u003eO limite conservador indicado no manual é de 1280W em contínuo (12,8V × 100A para carga e descarga), com um impulso de 400A durante um segundo para a corrente de arranque. Planeie todas as cargas contínuas para que não ultrapassem 1280W. As imagens de marketing da GSIKE para este conjunto indicam uma classificação BMS superior e um eletrodoméstico maior; considere 1280W como o valor de referência para o planeamento e confirme a classificação BMS real com o vendedor antes de ligar qualquer equipamento acima desse valor (consulte a nota sobre as especificações). Ligar baterias em paralelo aumenta a corrente — uma única bateria de 300Ah não aumenta o limite de 1280W.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eUma bateria de 300Ah substitui mesmo seis baterias de chumbo-ácido?\u003c\/summary\u003e\n\u003cp\u003eAproximadamente, no mesmo barramento de 12V. Uma GSIKE de 300Ah fornece ~3818–4019 Wh utilizáveis com uma profundidade de descarga de ~95–100%, enquanto uma bateria de chumbo-ácido inundada de 12V e 100Ah fornece apenas ~504 Wh utilizáveis com 42% de DoD. Assim, uma GSIKE substitui cerca de seis baterias de chumbo-ácido de 12V e 100Ah ligadas EM PARALELO no barramento de 12V. Nunca as ligue em série para obter 24V — trata-se de um sistema diferente.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003ePorque é que a de 300Ah continua limitada a 1280W, apesar de armazenar cerca de 3× mais energia do que a de 100Ah?\u003c\/summary\u003e\n\u003cp\u003ePorque energia (Wh) e potência (W) são duas coisas diferentes. Esta gama GSIKE de 12 V usa o mesmo BMS de 100 A, quer a bateria tenha 100 Ah ou 314 Ah, pelo que, a 12,8 V, o limite de potência contínua é 100 A × 12,8 V = 1280 W em cada unidade. As células adicionais apenas prolongam a autonomia (4019,2 Wh contra cerca de 1,28 kWh) - não aumentam o limite de potência de uma única bateria. Para obter mais potência contínua, ligue unidades compatíveis em paralelo (a corrente aumenta e a tensão mantém-se nos 12,8 V) ou monte um banco de tensão mais elevada em série. Até lá, nunca planeie uma carga contínua superior a 1280 W numa única bateria de 300 Ah.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eQuanto tempo alimentará o meu frigorífico, as luzes e os aparelhos?\u003c\/summary\u003e\n\u003cp\u003eCom base nos 3840 Wh indicados na etiqueta, divididos pela carga: 100 W → 38,4 h, 300 W → 12,8 h, 500 W → 7,68 h, 800 W → 4,8 h e 1000 W → 3,84 h. Mantenha todas as cargas contínuas no limite de 1280 W ou abaixo. No limite máximo, o banco dura cerca de 3,0–3,14 h. Se utilizar um inversor de 12 V separado, tenha em conta uma eficiência de cerca de 90–95% e deixe uma margem na profundidade de descarga.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eComo posso expandir o banco - em série ou em paralelo, e até que limite?\u003c\/summary\u003e\n\u003cp\u003eA configuração máxima é 4P4S: quatro unidades em paralelo vezes quatro em série = 16 unidades, o que resulta em 51,2 V e 1256 Ah, num total de 64,3 kWh. Ao montar um banco, use unidades do mesmo modelo, com datas de produção e histórico de carga com uma diferença de cerca de um mês, no máximo; não misture unidades novas com unidades muito usadas e mantenha todo o banco com o perfil de carga de 14,4 V e o corte aos 10 V.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eA caixa indica 300 Ah, mas o manual indica 314 Ah \/ 4019,2 Wh - em que classificação devo confiar?\u003c\/summary\u003e\n\u003cp\u003eAmbas, para fins diferentes.

Use 314 Ah \/ 4019,2 Wh para comparar especificações e os 3840 Wh indicados na etiqueta para estimar a autonomia. A diferença de cerca de 180 Wh deve-se ao arredondamento da gama, não corresponde a uma segunda bateria e não altera o BMS de 100 A, o limite de 1280 W nem a classificação de 6000 ciclos.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eQuanto pesa a bateria de 300 Ah e como devo transportá-la ou montá-la?\u003c\/summary\u003e\n\u003cp\u003ePesa 26 kg líquidos (27 kg brutos) - é mesmo pesada, por isso planeie levantá-la a dois e use as pegas integradas para a inclinar ao colocá-la num compartimento de uma autocaravana ou de um barco. Fixe-a pela base com os terminais M8 e o material fornecido, mantenha-a na vertical, deixe espaço para ventilação em redor da caixa de ABS e use cabos de 12 V grossos e curtos.

— 300Ah or 314Ah?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The engineering cells are 314Ah \/ 4019.2Wh (12.8V × 314Ah). 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. Because the charge window is 0°C to 50°C, mount it where the space stays above freezing in winter; do not charge below 0°C even though discharge works down to −20°C.\"}}, {\"@type\": \"Question\", \"name\": \"Will it work for a golf cart or a trolling motor?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Not for a golf cart — this is a 12V leisure \/ deep-cycle pack, not a traction battery for the high continuous drive current of a golf-cart system. It is well suited to an electric trolling motor on a boat (several buyers report a full day on one charge), as well as campervans, motorhomes, off-grid cabins, home solar storage and camping.\"}}, {\"@type\": \"Question\", \"name\": \"What about the weight, warranty, shipping and returns?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The pack weighs 26kg net (27kg gross) — plan a two-person lift. 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\nEtiquetas: bateria LiFePO4 de 12 V e 300 Ah, bateria de lítio de 300 Ah, 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 de lazer de 300 Ah, bateria LiFePO4 de 4019 Wh\u003cbr\u003e\nbateria LiFePO4 de 12 V e 300 Ah, bateria de lítio de 300 Ah, 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 de lazer de 300 Ah, bateria LiFePO4 de 4019 Wh, comprar bateria LiFePO4 de 12 V e 300 Ah na Europa, bateria LiFePO4 de 12 V e 300 Ah por menos de 370 EUR, bateria LiFePO4 de 12 V e 300 Ah em armazém da UE, preço da bateria GSIKE de 12,8 V e 300 Ah, comparação de preços de baterias de lítio de 12 V e 4 kWh na Europa\u003cbr\u003e\ncomprar bateria LiFePO4 de 12 V e 300 Ah na Europa, bateria LiFePO4 de 12 V e 300 Ah por menos de 370 EUR, bateria LiFePO4 de 12 V e 300 Ah em armazém da UE, bateria de lítio de 300 Ah para autocaravana, bateria LiFePO4 de 300 Ah para cabana autónoma com energia solar, preço da bateria GSIKE de 12,8 V e 300 Ah, bateria de lítio de 12 V e 300 Ah com envio gratuito para a Europa, bateria de lazer de 300 Ah no Reino Unido e na Europa, bateria solar de 12 V e 300 Ah para armazenamento de energia doméstico, bateria LiFePO4 de 12 V e 300 Ah com devoluções e garantia de 30 dias, bateria LiFePO4 de 12 V e 300 Ah em stock na Europa, entrega em 2-7 dias, comparação de preços de baterias de lítio de 12 V e 4 kWh na Europa\u003cbr\u003e\nbateria de lítio de 100 Ah vs 300 Ah, quantos kWh tem uma bateria de 300 Ah, quantos dias de autonomia oferece uma bateria de 300 Ah, durante quanto tempo uma bateria LiFePO4 de 300 Ah consegue alimentar aparelhos, que tamanho de bateria para uma casa autónoma com energia solar, baterias LiFePO4 de 12 V em série vs em paralelo, banco de baterias LiFePO4 4P4S de 64 kWh, quanto pesa uma bateria LiFePO4 de 300 Ah, como carregar uma bateria LiFePO4 de 300 Ah, LiFePO4 de 300 Ah vs 200 Ah: de qual preciso, quantas baterias de chumbo-ácido substitui uma bateria LiFePO4 de 300 Ah, calculadora de autonomia de bateria de 12 V e 300 Ah\u003cbr\u003e\nmelhor bateria LiFePO4 de 12 V e 300 Ah na Europa em 2026, GSIKE vs LiTime 12 V e 300 Ah LiFePO4, GSIKE vs Renogy 12 V e 300 Ah LiFePO4, Redodo 12 V e 300 Ah LiFePO4 vs GSIKE, análise da bateria Power Queen 12 V e 300 Ah LiFePO4, Eco-Worthy 12 V e 300 Ah LiFePO4 vs GSIKE, Easun 12 V e 300 Ah LiFePO4 vs GSIKE, análise da bateria Datouboss 12 V e 300 Ah LiFePO4, GSIKE 100 Ah vs 300 Ah: que bateria escolher, LiTime 300 Ah vs Renogy Core 300 Ah LiFePO4, bateria LiFePO4 barata de 12 V e 300 Ah na Europa, bateria LiFePO4 de 12 V e 300 Ah por menos de 400 EUR na Europa\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\/pt\/products\/gsike-12-8v-300ah-lithium-energy-storage-battery-for-solar-power-system","provider":"Gsike","version":"1.0","type":"link"}
