Tempereture switch 8S 8A Lifepo4 battery protection bms board with balance

1. About the bms
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.Please consult the salesman for specific parameters.

Beskrivning:
The protection plate is a semi-finished product, which needs to be used in combination with the battery. Before use, please make sure that the battery is in good consistency (internal resistance voltage multiplying ratio). This product contains technical knowledge. Once installed incorrectly, it will lead to board burning, tube bursting and other situations. Please explain in detail before installation. Novice buyers should install it under the technical guidance.

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 4-8 strings, the example picture is 8 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) .
