Description:
The module has the functions of over-charge protection, over-discharge protection, and short circuit protection. Safety and reliability.
Battery heating in use means that battery rate is not applicable. This situation can not be used for a long time and the battery will be damaged quickly.
There are 10 MOS transistors, strong heat dissipation aluminum sheet, upper limit of continuous current 100A. Suitable for 4 series battery packs, such as inverter, a xenon lamp, solar street lamp, etc.
Current: 100-120A
Charging Voltage: 16.8V
Charging current: 10A (Max)
Balanced Current of Electricity: 45mA
Working temperature: -20~80 degree C
Dimension: 70 x 60 x 8.5 mm
