48V E-bike lithium ion battery BMS, 13S 48V 20A BMS, Charging Voltage 54.6V, With balance function and ON/OFF switch.


1. It is suitable for 13S 48V lithium ion battery pack.

2. With functions of protection from voltage, current detection, including over-current, overvoltage, under-voltage and short circuit protection.

3. This BMS has applied with high quality IC chip specially for lithium battery protection purpose .highly detection
precision degree on over-charge,over-discharge,voltage balancing ,and with detection on wires disconnection functions,
with three layers of over-discharge and over-current detections and delay times in detecting process.( Over-current 1,
over current 2,short cicircuit protection ),with charging protection functions at the charging port so as to avoid reverse

connection problem from the charger . short-circuit of charging port ,with two layers protection against over-voltage
when charging :This is The PCB for 13 series 48V(54.6v)  lithium ion  battery pack with  15A constant  discharge current 

and Max 4A charging current  .the charge and discharge port is different.

Wiring instructions:

power cable

B-:Connect to battery negative  (Black cable 14AWG  L=150±5mm)

P-:Connect to negative of discharge port (Blue cable  14AWG  L=150±5mm) 

C-:Connect to negative of charge port (Black cable  18AWG  L=150±5mm) 


Voltage monitoring cable

cable type:UL1007   22AWG   L=300±5mm
B-(GND,)/B1/B2/B3/B4/B5/B6/B7/B8/B9/B10/B11/B12/B13 (B+)


Please connect B- line firstly, and then connect voltage monitoring wiring harness. The last step is to connect charge and discharge lines. If you want to remove them, the order should be reversed. Please pay attention to the connection order, or it will damage the component.
