BMS 2S (8.4V – 20A) Lithium Battery Protection Module
NOTE: after batteries connected to BMS please connect charging voltage for short time to the BMS to activate it.
Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions)
Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balancing)
Charging voltage: 8.4V – 9.0V
Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use)
Continuous charge current (upper limit): 10A
Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function.
Note 1:
The successful start of power drill requires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary 18650 can not start drill! ! !); 0V and 8.4V cable, use 2 square mm Above copper wire (cannot use nickel plate!!!)
Note 2:
Connect 0V, 4.2V, 8.4V according to the diagram strictly. When connecting the battery for the first time, it needs to be charged before output.
Note 3:
When the battery is charged, “430” resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the “430” resistance is also heating in the state of not charging, please check whether the wrong line is connected.
For some customers with poor electronic foundation, please explain: Do not mix good batteries and bad batteries together! The capacity/internal resistance of 2 batteries should be as close as possible! (1 good battery + 1 bad battery = 2 battery use effect).
