BSLBATT 12V 7Ah LiFePO4 Battery – Deep-Cycle SLA/AGM Replacement for Wheelchairs, Scooters & UPS (B-LiFePO4-12-7)

The BSLBATT 12V 7Ah is a deep-cycle lithium iron phosphate (LiFePO4) battery built as a direct, plug-and-play replacement for 12V 7Ah sealed lead-acid (SLA), AGM, and gel batteries. A built-in Battery Management System (BMS) protects against overcharge, over-discharge, short circuit, and overheating, so you get more usable power at a fraction of the weight.

Why upgrade from lead-acid?

• About 60% lighter than an equivalent 12V 7Ah SLA — ideal for electric wheelchairs and mobility scooters.
• Up to 10× longer life — roughly 2,000–5,000 charge cycles vs ~300–500 for lead-acid.
• More usable capacity — discharge deeper than SLA for longer real-world runtime.
• 100% maintenance-free and safe in non-ventilated battery boxes (no acid, no off-gassing).
• Flat voltage curve — runs at full power until nearly empty.

Common uses

Electric wheelchairs and mobility scooters, UPS / battery backup, alarm and security panels, emergency lighting, and general 12V deep-cycle applications.
