Planlæg, så alle konstante belastninger er på højst 1280W. GSIKEs markedsføringsgrafik for denne batteripakke viser en højere BMS-klassificering og et større apparat; brug 1280W som planlægningstal, og få bekræftet den faktiske BMS-klassificering hos forhandleren, før du tilslutter noget over denne grænse (se specifikationsnoten).

De ekstra celler forlænger kun driftstiden (4019.2Wh mod ~1.28kWh) - de hæver ikke effektgrænsen for én batteripakke. Hvis du vil trække flere watt kontinuerligt, skal du forbinde enheder med samme specifikation parallelt (strømmen lægges sammen, mens spændingen forbliver 12.8V) eller bygge en batteribank med højere spænding ved at forbinde dem i serie; indtil da må du aldrig planlægge en vedvarende belastning på over 1280W fra én enkelt 300Ah-enhed.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHvor længe kan den drive mit køleskab, lys og apparater?\u003c\/summary\u003e\n\u003cp\u003eVed mærkepladens 3840Wh divideret med belastningen: 100W → 38.4h, 300W → 12.8h, 500W → 7.68h, 800W → 4.8h og 1000W → 3.84h. Hold alle kontinuerlige belastninger på eller under grænsen på 1280W; ved fuld belastning holder banken ~3.0–3.14h.

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.
