14S 60A lipo lithium Polymer BMS/PCM/PCB battery protection circuit board for 14 Packs 18650 Li-ion Battery Cell with Balance with temperature switch
this BMS can use in E-bike. Elecric cars.
Note: this BMS with balance function. your battery need match, battery should have good consistency, if not sure, please use new brand battery.
this is version S, charge and discharge use same port.
if you want charge and discharge use the difference port, please select version D.
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.
30A version: continuous work current 30A, over current protect is 30*2=60A
40A version: continuous work current 40A, over current protect is 40*2=80A
60A version: continuous work current 60A, over current protect is 60*2=120A
60A Parameter:
over charge: 4.25V
over discharge: 2.8V
charge voltage: 4.2V * 14 = 58.8V
continuous work current: 60A
over current: 120A
balance voltage: 4.2V
balance current: 50mA
size: 95mm * 87mm * 10mm
version S: charge and discharge use same port
charge: B+ and C-
discharge: B+ and C-
(do not use P-, P- is for difference version. )
Wiring sequence: First solder line B- to battery negative, connect balance cable to battery(B1 B2 ... B14), 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, first low bit(BC0), last high bit(BC14)
Applications:
14S Li-ion18650,LiCoO2,LiMn2O4,Li(NiCoMn)O2 rechargeable batteries
14S Lipo rechargeable batteries
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.
