Product Description
What is this product?
The BP Series is a 12.8V lithium iron phosphate (LiFePO₄) battery pack designed as a direct 1:1 drop-in replacement for lead-acid and gel batteries. Available in capacities from 50Ah to 200Ah (640Wh to 2560Wh), it offers a cost-effective upgrade for 12V and 24V home energy storage systems. No modification to existing battery trays or wiring is required.
Why choose LiFePO₄ over lead-acid?
-
Longer Lifespan: 2500+ cycles (vs. 300-500 cycles for lead-acid)
-
Lighter Weight: Up to 70% weight reduction
-
Higher Usable Capacity: 100% depth of discharge (vs. 50% for lead-acid)
-
Maintenance-Free: No water refilling or acid leaks
-
Wide Temperature Range: Discharge from -20°C to 60°C

Common Specifications:
-
Nominal Voltage: 12.8V
-
Max Charging Voltage: 14.0~14.6V
-
Discharge Cut-off Voltage: 10.0V
-
Cycle Life: 2500 cycles @ 0.2C until 80% capacity retention
-
Self-discharge Rate: 53.5% per month at 25°C (charge every 3 months)
-
Charge Temperature: 0°C to 45°C
-
Discharge Temperature: -20°C to 60°C
-
Casing Material: Iron
-
BMS: Built-in (overcharge, over-discharge, overcurrent, short circuit, temperature protection)
Technical Note: The BMS (Battery Management System) handles all protections. For standard charging, use CC/CV mode: charge at 0.2C constant current to 14.6V, then hold at 14.6V constant voltage until current drops below 0.02C.
