12V 7Ah LiFePO4 Battery, Replace 6FM7 SLA Lead Acid Battery, Max 10A Discharge, Max 2 in Series & 4 in Parallel, for Power Wheels, Fish Finder, Solar System, Garage Door Opener, Alarm Backup Power

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 1.76 lbs 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. Batteries are shipped at partial charge for transport safety. Please fully charge before first use.
