48V 50Ah Electric Wheelchair Smart Lithium Iron Phosphate Battery pac

【Uncompromising Quality】

Vastsea latest 48V battery achieves outstanding performance with over 4500 cycle life, retaining 80% capacity after 4500 cycles. It supports up to 50A maximum discharge current and is backed by a generous 5-year warranty.

【Self-Heating Function】

The built-in intelligent self-heating system activates automatically when the internal battery temperature falls below 5°C (41°F), enabling normal charging and stable operation even in cold weather conditions.

【Reliable BMS System】

The upgraded Battery Management System (BMS) adopts high-performance dual processors. It effectively resists load fluctuations and keeps all battery cells in precise voltage balance.

【Low Temperature Protection Function】

This lithium battery is equipped with low-temperature charge and discharge protection. It automatically stops charging below 0℃ and cuts off discharge output when the temperature drops below -20℃.

【Auto-balancing Function】

Thanks to the intelligent auto-balancing design, you can connect multiple batteries in parallel effortlessly, effectively improving overall charging efficiency and long-term service performance.

Vastsea New Energy lithium-ion battery provides 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 such as yachts. It delivers over 2000 life cycles at 80% depth of discharge (DOD).

Premium-grade battery cells ensure a service life of over 2000 cycles, a 100A continuous discharge current, and reliable performance across a wide operating temperature range.

Effortlessly upgrade to lithium power with the standard BCI group size. This battery offers higher energy density, deeper discharge capability, better round-trip efficiency, and faster charging speeds compared to traditional batteries.

The advanced Battery Management System (BMS) with high-performance dual processors provides comprehensive protection against short circuits, overcharging, and overheating, while maintaining balanced voltage across all cells.

This lithium battery features dedicated low-temperature charge and discharge protection. It automatically stops charging when the temperature drops below 0℃ and ceases discharging when the temperature falls below -20℃.

The built-in auto-balancing function allows you to easily connect multiple batteries in parallel, improving long-term average charging efficiency.

The software-controlled BMS continuously monitors the battery’s operating conditions and oversees its safe operation. It tracks real-time conditions, redistributes energy instantly, and sends alerts in the event of any anomaly.

After 24 hours of inactivity (neither charging nor discharging), the battery automatically enters energy-saving mode. With a low self-discharge rate of only 3% per month, it retains power for longer periods. For storage, please charge the battery to 30%~50% capacity and disconnect it from the system.

Thanks to the reliable auto-balancing function, identical batteries can be safely connected in parallel to expand power capacity. Up to 8 units are supported for parallel connection.

The intelligent built-in BMS safeguards the entire charging and discharging process by protecting the battery from overcharge, overdischarge, overcurrent, high temperatures, and short circuits.
