48v Lithium ion Battery Pack
Battery voltage, capacity, size and case can be made to order.
Plugs, sockets, cables and waterproof features are customizable.
We can customize special battery packs for any use case.
BMS charging/discharging current, balancing function and communication protocols can be adjusted as needed.
When charging a series of lithium batteries, it is essential to ensure that each cell is charged evenly; otherwise, the performance and lifespan of the entire battery pack will be affected during use. Common equalization charging techniques include constant shunt resistor equalization charging and switching the shunt resistor on and off.
