Li-ion cell 13S 48V 50A BMS, For 48V 30Ah 40Ah 50Ah lithium ion battery pack, Working current 50A, 1500W-2000W, With balance function.
Features:
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 circuit 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 50A constant discharge current
and 15A charging current .the charge and discharge port is different.

Wiring instructions:
power cable
B-:Connect to battery negative (Black cable 12AWG L=150±5mm)
P-:Connect to negative of discharge port (Blue cable 12AWG L=150±5mm)
C-:Connect to negative of charge port (Black cable 14AWG L=150±5mm)
Voltage monitoring cable
cable type:UL1007 22AWG L=300±5mm
B-(Black),B13+(Red)
B-(GND)/B1/B2/B3/B4/B5/B6/B7/B8/B9/B10/B11/B12/B13 (B+)
Remarks:
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.
