51.2V 24Ah LiFePO4 Battery Pack FAQs
Is it safe for deep discharge?
LiFePO4 batteries handle deep discharges (up to 90% DoD) better than lead-acid or other lithium types.
Built-in BMS (Battery Management System) prevents over-discharge, overcharge, and short circuits.
What is the lifespan of this battery?
The LiFePO4 chemistry provides 3000+ charge cycles (to 80% capacity), significantly outlasting lead-acid or standard lithium-ion batteries. Proper charging (using a compatible BMS) maximizes lifespan.
What devices is this battery compatible with?
urban natural gas equipment
Marine equipment (electric boats, diving scooters)
Outdoor solar storage & emergency power
Industrial waterproof applications
