We have more 30 types of cells, and could make OEM battery pack from 12v-200v, 10-200ah, which can be used in electric vehicle, E-bike, UPS, energy storage system, telecommunication base station, E-scooter, E-tools,unmanned airplane, golf cart, fork lift, cleaning car , electric wheelchair, etc.
These cells are very safe in normal operation, DO NOT cause fires as the early Lithium Phospate batteries.
The selected batteries solve the Safety concerns of being in an Electric Vehicle (EV) / Electric Car Conversion Kit, every cell has a built-in safety device if punctured or damaged, will vent to the atmosphere making the cell much safer.
