Humsienk 12V 200Ah Plus 2560Wh LiFePO4 Battery for RV & Marine

Yes, this battery includes a 250A BMS (Battery Management System) that provides full protection against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes. However, this model doesnothave Bluetooth monitoring. To check battery status (voltage, current, state of charge, etc.), you will need to use a compatible external monitor.

The 12V 200Ah LiFePO4 battery provides 2.56kWh of usable energy (12V × 200Ah = 2,560Wh, typically rounded to 2.56kWh). Unlike lead-acid batteries, you can safely use over 100% of this capacity without damaging the battery, giving you more usable power than a comparable lead-acid bank.

Yes. You can connect up to 4 batteries in parallel (12V, capacity increases to 400Ah / 600Ah / 800Ah) for longer runtime. You can also connect them in series to reach 48V (four batteries in series) — but do not exceed 48V. All batteries should be identical, fully charged, and from thea same batch for optimal performance. No parallel communication cables are needed; simply connect positive to positive, negative to negative.

You need a charger with a LiFePO4 profile set to 14.2V–14.6V for bulk/absorption charging, with a float voltage around 13.6V–13.8V. The recommended charge current is 40A–100A (0.2C to 0.5C), with a maximum of 100A.

Most modern MPPT solar charge controllers (Victron, Epever, Renogy, etc.) and inverter/chargers work perfectly as long as you select the LiFePO4 or "Lithium" battery type. If your solar charge controller does not have a LiFePO4 preset, you can manually set the absorption voltage to 14.4V and float to 13.6V.

Important: Do not use a standard lead-acid charger with a desulfation or equalization mode, as the high voltage (15V+) can permanently damage the LiFePO4 battery.
