About the battery BMS/PCB/PCM

Function_^:^{Detect and protect the battery from over-charge ,over-dicharge, over-current short-circuit ,temperature detecting protection and auotmatically voltage balance function .}

^{Build with high end electronic components (High End IC and MOSFET ) ,simple structure design will let it have more stable quality working performance , Flexible application
( it can be used for less series battery by leaving some connection pins at empty status ),full set of protection measures let it works well without any infulence from external unexpected accidents.}
If you feel that this product does not meet your requirements, you can consult our staff, you can recommend or customize the lithium battery protection board you want.

Wiring:
1. First connect the B- of the BMS to the total negative pole of the battery pack;

2.The cable starts from the thin black one connecting B-, the second red wire connects the positive pole of the first string of batteries, and the next string is connected in turn to positive pole of the battery,B-,B1,B2……B8; then insert the cable into the BMS; (The maximum number of strings is 4-13 strings, the example picture is 13 strings) (Please weld the wires in order and avoid pseudo solder joints.)
3. Connect Charger C-/Load P- with BMS C-/P- (Use larger size wires)
4. Connect Positive Pole: Charger C+/Load P+ with Battery Pack B+ (Use larger size wires) .

3. FAQ
Q: How do I judge what material my battery is ?
ΕΝΑ: Please take a look at the battery body.
LiFePO4 battery: if the normal voltage of your battery shows 3.2V or 3.3V.
Li-ion or Li-polymer battery: if the normal voltage of your battery shows 3.6V or 3.7V.
LTO battery: if the normal voltage of your battery shows 2.3V or 2.4V.
