ANT BMS 28S smart board LiFePO4 BMS/PCM/PCB battery protection board for 28 Pack 18650 LiFePO4 Battery Cell with balance function with temperature switch
Only support Android smartphone, the APP only support android. we have English version APP.
Li-ion(3.7V), 8S to 32S all can support.
LiFePO4(3.2V), 8S to 32S all can support.
LTO(2.4v), 10S to 32S all can support .
Note: this BMS with balance function. your battery need match, battery should have good consistency, if not sure, please use new brand battery.
with LCD version: BMS add LCD
without LCD version: just BMS, no LCD.
80A version: continouse work current is 80A , peak current 100A
100A version: continouse work current is 100A ,peak current 200A
120A version: continouse work current is 120A ,peak current 300A
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.
APP DEMO
wiring diagram
charge: B+ and C-
discharge: B+ and C-
Wiring sequence: First solder line B- to battery negative, connect balance cable to battery(B1 B2 ... Bn), 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: plug the balance cable(socket) first insert low bit battery(B-), then insert high bit battery(B+).
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.
6) Please note that it is without balance function.
