• Energy storage for isolated/off-grid site

Integration advice (essential)

• LiFePO4 Charging: aim for 14.6 V · no prolonged “float” needed · charging automatically cut off at -7 °C by the BMS.
• Series/Parallel: assemble only with identical batteries (same model/age/SOC), cables of the same length/section, balancing recommended before assembly.
• Wiring: sections adapted to the current (e.g., high currents <=200 A → large section, fuse close to the + terminal, DC circuit breaker recommended).
• Wintering: storage ~50% SOC, 10–20 °C, quarterly check.

Why this battery?

• No maintenance · long lifespan (~3000 cycles)
• Built-in display + alarms for quick diagnostics
• Multilingual Bluetooth (convenient tracking on smartphone)
• Resistant to low temperatures during discharge

2-year warranty
