Large scale and mechanized production with high quality. High temperature, low temperature and corrosion resistance, battery performance is stable.
The battery has high safety performance, no explosion and no pollution combustion; Non-toxic, pollution-free, low internal resistance, reduce battery self-discharge, extended using time.
Source manufacturer, power, capacity, voltage, length, width, circuit board, etc, can be customized, welcome to sample customization processing to meet your various needs.
Original imported battery, It is widely used for lithium battery packs such as DIY electric vehicles, motorcycles, solar storage systems. It can also assemble inverter batteries, headlights, aircraft models, mobile power supply, energy storage, solar lamps, external power supply, etc.
Strictly control every detail, conduct effective sampling inspection for each batch of finished products, and pursue zero defects.
Overcharge: After charge, tested the batteries' initial state and capacity. Charge to 10.0V at 3C current, then charge to 0.01C at CV mode, and observe changes in appearance.
Over discharge: After charge, test the batteries' initial state. When the batteries are normal, discharge to 0V at 0.5C and observe changes in appearance.
