About this product

REPLACEMENT & LIGHTWEIGHT DESIGN:This 12.8V 7Ah LiFePO4 battery directly replaces 6FM7 12V7Ah lead-acid batteries, sized 5.94*2.56*3.71 inch with only 1.76lbs weight, far lighter than traditional lead acid cells. Equipped with built-in intelligent BMS board to support 10A max continuous discharge, delivering stable power and over 1500 long service cycles without memory effect. AUTHORIZED SERIES & PARALLEL RULES:Confirmed by engineering team, max 2 identical batteries in series and max 4 identical batteries in parallel for capacity expansion. Never exceed the quantity limit, avoid mixing different batches or battery types, and forbid series-parallel mixed connection to prevent circuit damage. SPECIFIC LOW-POWER APPLICATIONS:Perfect for kids ride-on toys, fish finders, mini solar storage, garage door opener backup and security alarms. It cannot be applied to 120V high-power motors, heavy lawn mowers or high-power amplifiers, which will trigger BMS overcurrent protection and cut power automatically. STANDARD CHARGING & STORAGE TIPS:Only use a 14.4V dedicated LiFePO4 charger within 1A-5A. Lead-acid chargers cause incomplete charging and severe power loss. Recharge the battery every 30 days during long-time idle storage to avoid irreversible over-discharge. FULL BMS PROTECTION & 1-YEAR WARRANTY:The integrated BMS provides all-round protection against overcharge, over-discharge, overcurrent and short circuit for safe daily use. We offer a 1-year warranty on manufacturing defects, while damage caused by mismatched chargers, overload and wrong wiring is not covered.
