About the battery BMS/PCB/PCM
Function: Detect and protect the battery from over-charge ,over-dicharge, over-current short-circuit ,temperature detecting protection andauotmatically 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.

Mode	LWS-4S40A-050(4S)
PCM Size	L120W60T10 mm
battery series	4sAvailable
working current	40A Available
Application	LED lights, Emergency lights, Digital Equipment, etc

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......B4; then insert the cable into the BMS; (The maximum number of strings is 4 strings, the example picture is 4 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) .
