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