I replace two 12V 100Ah lead-acid batteries with this one GSIKE unit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, for the same usable 12V capacity. One GSIKE 12.8V 100Ah delivers ~1216–1280 usable Wh at ~95–100% depth of discharge, whereas a 12V 100Ah flooded lead-acid is limited to about 42% DoD — roughly 504 usable Wh. So one GSIKE replaces two 12V 100Ah lead-acid batteries wired in parallel (same 12V). Do not wire them in series, which would produce 24V and is a different system.\"}}, {\"@type\": \"Question\", \"name\": \"What charger do I need — will my old lead-acid charger work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"You need a lithium \/ LiFePO4-capable charger or solar controller set to CC\/CV at 14.4V ±0.2V, with a recommended charge current of 20A (0.2C; the BMS allows up to 100A). A legacy lead-acid charger that only floats at 13.5–13.8V without a LiFePO4 charge profile will not fully charge this battery. The battery itself is not a charger — it only stores and releases power.\"}}, {\"@type\": \"Question\", \"name\": \"Can I charge it in winter or below freezing?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No — the charge window is 0°C to 50°C and the BMS stops charging around 55°C. Do not charge below 0°C. Discharge works down to −20°C, and storage should be between −10°C and 50°C at roughly 50% charge.
