    Product Introduction

    This 12V 7Ah LiFePO₄ battery pack is assembled with automotive-grade LiFePO₄ cells, featuring a chemically stable cathode that eliminates thermal runaway risks. It is a drop-in replacement for 12V lead-acid batteries and outperforms SLA batteries where it matters most: one-third the weight for easy transport, four times the cycle life for fewer replacements, and no acid leakage for indoor safety.

    With a flat discharge curve, ultra-low self-discharge, and built-in BMS protection against over-charge, over-discharge, and short circuits, the pack delivers reliable power for low-to-moderate current applications. Realizing true maintenance-free operation with 12-month shelf life and over 3000 cycles at 70% DOD, it is an ideal upgrade for alarm systems, backup lighting, access controls, and small medical carts where downtime is not an option.
