30S 150A LiFePO4 BMS/PCM/PCB battery protection board for E-bike 30 Packs 18650 Battery Cell with Balance function with temperature switch
100A version: continuous work current 100A, over current protect is 300A.
120A version:continuous work current 120A, over current protect is 360A.
150A version: continuous work current 150A, over current protect is 450A.
Note: this BMS with balance function. your battery need match, battery should have good consistency, if not sure, please use new brand battery.
Features:
1) high-accuracy voltage detection circuit;
2) terminal of the charger using high voltage device;
3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);
4) MOS transistor can control the battery charge and discharge;
5) low standby current consumption.
150A Parameter:
over charge: 3.75V
over discharge: 2.1V
charge voltage: 3.65V * 30 = 109.5V
continuous work current: 150A
over current: 450A
balance voltage: 3.6V
balance current: 50mA
size: 189.5mm *145mm * 15mm
we will send with balance cable(balane wire)
version S: charge and discharge use same port
charge: B+ and C-
discharge: B+ and C-
Wiring sequence: First solder line B- to battery negative, connect balance cable to battery(B1 B2 ... B30), double check the voltage, check ok, then insert the cable(socket), then connect C- line, then look at the amount of the total voltage of the battery, if the voltage between C- and B+ equal the total voltage, it’s should be work properly.
step 1: connect battery, check carefully
step 2: plug the balance cable(socket) first low bit, last high bit.
Applications:
30S lifepo4 Rechargeable batteries
Notice:
1) Please note that the input and output voltage, and load current conditions for power protection board does not exceed the electrical parameters of the allowable power consumption;
2) special attention to the load current can not work long hours between maximum continuous operating current and over-current protection current;
3) When connecting the battery ,it may not discharge. In this case, connect the charger can be restored to normal working condition;
4) Although the BMS built-in electrostatic protection circuit, but please do not hand touch when BMS in the working condition, so as to avoid damage from static electricity protection board.
5) If the picture is not the same as the parameters,please check according to the parameters table.
