22S 100A high current smart board LiFePO4 BMS/PCM battery protection board for 18650 LiFePO4 Battery Cell with Balance with APP for electric cars application
the board not include Bluetooth and USB to seiral tools.
Bluetooth or USB to serial Need to purchase separately
Note: this BMS with balance function. your battery need match, battery should have good consistency, if not sure, please use new brand battery.
USB to serial module or Bluetooth should use together with the board.
USB to serial module connect to PC by USB, so you can monitor the board, and set the parameter.
Bluetooth module can connect to smart phone, right now only support android 4.3 above.
APP support english
about software, please contact seller.
after order, seller will give you APP link.
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.
6) with UART interface, Bluetooth interface, support PC or smart phone.
7) over charge and over discharge can set by software( APP).
100A Parameter:
charge voltage: 3.65V * 22 = 80.3V
continuous work current: 100A
over charge: 3.6~4.3V
over discharge: 2.0~3.3V
balance voltage: 3.3~4.2V
balance current: 50mA
parameter can set by software(APP).
parameter can set by APP, follow table is DEMO
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 ... B22), insert the cable(socket), After check, 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: after check the voltage is ok, then insert the cable, first low bit(B1), last high bit(B22).

Applications:
22S LiFePO4 rechargeable batteries
electric cars
Notice:
1. Please pay attention to the use condition of input and output voltage and load current , make the protective plate within the power consumption of no more than specification allows power consumption;
2. Connect the battery will happen cannot discharge status, in this case, connect the charge can be restored to normal working state;
3.If a set of batteries with over-discharge and over-charge cells, the bms cannot be charge and discharge.
