LiFePO4 Smart Wheel Smart Drive Battery 38.4V4Ah

Upgrade your mobility or medical device power system with this 38.4V 4Ah LiFePO4 battery pack — a compact, lightweight 153.6Wh solution built on high-quality 26650 cylindrical cells in a 12S1P configuration. Engineered as a superior drop-in replacement for lead-acid batteries, this pack delivers more than 2,000 charge cycles at 100% depth of discharge — over five times the lifespan of conventional lead-acid alternatives — significantly reducing total cost of ownership.

Weighing just 1,100g and measuring only 117 × 70 × 91 mm, it is less than half the weight of comparable lead-acid batteries while occupying minimal space, making it ideal for mobility scooters, power wheelchairs, and compact medical seating systems. The built-in BMS provides comprehensive protection against over-charge, over-discharge, and over-temperature, with automatic cell balancing to ensure long-term reliability and consistent performance.

With 10A continuous discharge and a 20A pulse, it handles demanding load profiles with confidence. The pack operates across a wide temperature range — charging from 0°C to 50°C and discharging from -20°C to 60°C — and ships with pre-terminated TE connector cables for plug-and-play installation.
