12.8V 38Ah LiFePO4 Battery Pack Rechargeable Lithium Battery with Balance Charging
$75.00
Rechargeable 12.8V 38Ah LiFePO4 battery pack (462Wh) in a rugged hard case with fold-down carry handle and waterproof aviation connector. Built-in BMS with cell balancing, overcharge, over-discharge, overcurrent, and short-circuit protection. Suited for solar systems, backup power, RVs, and outdoor equipment.
This 12.8V 38Ah LiFePO4 battery pack delivers a typical capacity of 38Ah (minimum 36.1Ah under 0.2C standard charge/discharge) and approximately 462Wh total energy. Housed in a rugged hard case with a fold-down carry handle and a waterproof aviation-style connector, the pack is designed for portability alongside durability.
The built-in BMS provides comprehensive protection, including cell balancing, overcharge, over-discharge, overcurrent, and short-circuit protection, helping extend service life and ensure safe operation.
The pack supports standard charging at 0.2C (7.6A) with CV cutoff at 14.4V, or fast charging at 1C (20A), completing a full charge in ≤8 hours standard or ≤4 hours fast charge. Standard continuous discharge is rated at 0.2C (7.6A), with a maximum discharge current of 20A and discharge over-current protection triggering between 50-70A.
Operating temperature range is 0~45°C for charging and -20~45°C for discharging, with internal resistance ≤60mΩ (AC 1kHz). The complete pack weighs 4.85kg.
