* High quality with smart balance function
* Wholesale price
* ISO9001/ISO14001/CE/ROHS certificates
* Fast deliveryAbout 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.

Electric Switch, Temperature Switch, Balance, 5V output, NTC and etc, if you need any above accessories, please must to contact our sales fisrt. All items are customized as your requirements, if without any request after order placed, we will produce as original.

Product Paramenters:

Mode	LWS-4S200A-127(4S) LiFePO4
PCM Size	L126*W93*T12.5 mm
battery series	4S Available
working current	200A Available
Application	LED lights, Emergency lights, Digital Equipment, etc
Sample	available

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) .

Q: How do I judge what material my battery is ?
A: Please take a look at the battery body. LiFePO4 battery: 3.2V or 3.3V. Li-ion or Li-polymer battery: 3.6V or 3.7V. LTO battery: 2.3V or 2.4V.

Q: How to choose a suitable BMS/PCM for my battery packs?
A: Please tell us following required details and we will advice for you: Battery material & Battery series & Capacity & working current & Application (For example: LiFePO4 BMS, 13 series, charge 40A, discharge 40A, application for e-bike 1800W.)
 

Q: Do you have Minimum Order Requirement (MOQ)?
A: Small PCM: 10 PCS MOQ; Large PCM: 1 PCS MOQ. Sample orders or bulk orders are all welcome.
 

Q: Can I require products size?
A: We can provide various size and specification is per your requirements, also ODM / OEM is welcome.
