Double Battery Balance Discharger can manage two battery packs which fixed on your bike, low power, Consumption design ,Real-time detect the voltage of both two
battery packs, Battery on-line check.
·This module can make both two batteries to discharge together to power the ebike , it will auto compare the voltage of each battery and adjust the current output for each battery.
it can be an Uart port or Battery Charging port ,its depend on user’s wants
(currently default)

Net weight:
72V100A=225G
72V100A Model Size: 8*6.8*2.5cm
Used For: 2 Battery in Parallel / Double Capacity
Connection definition:
OUT: Connect with controller
COM: UART interface (Default None)
IN-A: Connect with Battery Pack A
IN-B: Connect with Battery Pack B
Working Process
1. MCU monitor voltage of both batteries in real time and send the volatage
value by UART if UART interface is available.
2. Auto Battery on-line detecting. Switch to the battery and make power output
if only one battery was connected with this module.
3. Switch to BAT-B automatically when the voltage of BAT-A is low than switch
point.
4. Stop power output when the voltage of both batteries are low than low-cut
point.
Important hint:
1, Thank you for Purchasing our Double Battery Pack Switcher, Read this manual carefully.
2, Make sure battery pack which connected with module has the same technical parameters you provided for us, unpredictable results can occur if you use the incompatible Double Battery Pack Switcher with your battery pack.
3, Warning: Do not touch it by your hand directly. it will become more hotter during discharging
