18S 150A lipo lithium Polymer BMS/PCM/PCB battery protection circuit board for 18 Packs 18650 Li-ion Battery Cell with Balance with temperature switch
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 version Parameter:
over charge: 4.25V
over discharge: 2.8V
charge voltage: 4.2V * 18 = 75.6V
continuous work current: 150A
over current: 300A
balance voltage: 4.2V
balance current: 50mA
size: 189.5mm * 145mm * 15mm
version S: charge and discharge use same port
charge: B+ and P-
discharge: B+ and P-
Wiring sequence: First solder line B- to battery negative, connect balance cable to battery(B1 B2 ... B18), insert the cable(socket), After check, then connect P- line, then look at the amount of the total voltage of the battery, if the voltage between P- 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(BC18)
Applications:
18S Li-ion18650,LiCoO2,LiMn2O4,Li(NiCoMn)O2 rechargeable batteries
18S 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.
