And one lithium battery

It is a lithium battery, which typically offers high energy density and a long life cycle compared to other battery types.

Specifications

• <p class="ql-align-center"> <strong>Spec / Parameter</strong></p><p class="ql-align-center"> <strong>Value / Typical Range</strong></p><p> Chemistry</p><p> Lithium-Iron-Phosphate (LiFePO₄) &nbsp;</p><p> Nominal Voltage</p><p> 12.8 V (often labeled “12 V” battery bank) &nbsp;</p><p> Capacity</p><p> 150 Ah → stores about 1.92 kWh (12.8 V × 150 Ah = ~1920 Wh) &nbsp;</p><p> Usable Energy</p><p> With proper depth-of-discharge (DoD), almost full usable — LiFePO₄ supports deep cycling better than lead-acid. &nbsp;</p><p> Cycle Life</p><p> 4,000 to 6,000+ cycles (some sources claim up to 7,000+ cycles under ideal conditions) — far more than traditional lead-acid. &nbsp;</p><p> Depth-of-Discharge (DoD)</p><p> Up to ~ 80–90% typical; safe for frequent cycling. &nbsp;</p><p> Charge Voltage (full charge)</p><p> ~ 14.2 – 14.6 V for a 12 V pack (i.e. ~3.55-3.65 V per cell in the pack) &nbsp;</p><p> Discharge Cut-off Voltage</p><p> Approximately 10 – 10.5 V (depending on pack specification) — to prevent over-discharge damage. &nbsp;</p><p> Continuous Discharge Current</p><p> Often around 100 A for a 150 Ah pack (i.e. 1C) — suitable for moderate loads. &nbsp;</p><p> Peak / Surge Discharge Current</p><p> Some packs support higher bursts (e.g. up to ~ 200 A) for short-term loads (e.g. motor-start, fridge). &nbsp;</p><p> Operating Temperature Range</p><p> Charge: ~ 0 °C to ~55 °C; Discharge: down to –20 °C up to ~ 60 °C (varies by manufacturer) &nbsp;</p><p> Self-Discharge Rate</p><p> Low — much less than lead-acid; retains charge longer when idle. &nbsp;</p><p> Protection / Battery Management</p><p> Built-in BMS (Battery Management System) for: over-charge protection, over-discharge protection, over-current protection, short-circuit protection, cell balancing, temperature protection, etc. &nbsp;</p><p> Form Factor / Use</p><p> Often built to be a drop-in replacement for 12 V lead-acid (SLA) batteries — making them compatible with many inverters and solar setups. &nbsp;</p><p> Expected Service Life</p><p> 10–15 years under normal usage (daily charge/discharge, moderate depth-of-discharge) thanks to LiFePO₄ chemistry and robust cycle performance. &nbsp;</p><p> </p>
