12V 50Ah LiFePO4 Battery Pack for Wheelchair
Features
【4 Times Longer Lifespan】
With over 2000 cycles at 80% DOD (around 5 years of daily use), the Vastsea 12V 50Ah LiFePO4 battery lasts 4 times longer than traditional lead-acid batteries.
【Powerful Output】
The Vastsea 12V 50Ah LiFePO4 battery delivers up to 640Wh power output, 2 to 3 times higher than most lead-acid batteries of the same size.
【High Discharging Performance】
It supports up to 50Ah continuous discharge current to run most household devices. Adopting premium LiFePO4 technology, the battery maintains stable capacity and performance in extreme temperatures from -20℃ to 60℃.
【Safe and Reliable】
The built-in smart BMS offers full protection against overcharge, overdischarge, overcurrent, high temperature and short circuit. Its fully sealed construction avoids acid leakage and corrosion, requiring minimal maintenance.
【50% Lighter & Compact】
Weighing only 14.7 lbs, this LiFePO4 battery features a smaller and lighter design while delivering higher power than standard lead-acid batteries. Lightweight build allows easy carrying and hassle-free installation.

Lithium-ion Wheelchair Battery
Vastsea New Energy lithium-ion battery offers full protection against dust and other particulates, as well as resistance to low-pressure water jets from any angle, making it suitable for most outdoor scenarios including yachts. It delivers over 2000 life cycles at 80% depth of discharge (DOD).
Uncompromising Quality
State-of-the-art battery cells ensure a lifespan of more than 2000 cycles, 100A continuous discharge current, and reliable performance across a wide operating temperature range.
Easy Upgrades
Seamlessly upgrade to lithium with the standard BCI group size. It features greater energy density, deeper discharge capability, higher round-trip efficiency, and faster charging speed compared to traditional batteries.
Reliable BMS System
The advanced Battery Management System (BMS) with high-performance dual processors provides protection against short circuits, overcharging, and overheating, while maintaining balanced voltage across all cells.
Low Temperature Protection
Equipped with dedicated low-temperature charge and discharge protection. It automatically stops charging when the temperature drops below 0℃ and ceases discharging at temperatures below -20℃.
Auto-Balancing Function
The built-in auto-balancing function allows multiple batteries to be easily connected in parallel, improving long-term average charging efficiency.
Advanced Intelligent BMS
The software-controlled BMS continuously monitors the battery’s operating conditions and oversees safe operations. It tracks real-time conditions, redistributes energy instantly, and sends alerts in the event of anomalies.
Energy Saving Mode
The battery automatically enters energy-saving mode after 24 hours of inactivity (no charging or discharging). With a monthly self-discharge rate of only 3%, it maintains charge for extended periods. For storage, please charge the battery to 30%~50% capacity and disconnect it from the system.
Safe Parallel Expansion
With its robust auto-balancing function, identical batteries can be safely connected in parallel to extend power capacity. Up to 8 batteries are supported for parallel connection.
Comprehensive Charge & Discharge Protection
The integrated intelligent BMS circuit ensures safe charging and discharging by protecting the battery from overcharge, overdischarge, overcurrent, high temperatures, and short circuits.
