 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.

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.

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.....B15; then insert the cable into the BMS; (The maximum number of strings is 4-24 strings, the example picture is 15 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 ?
A: Please take a look at the battery body.if the normal voltage of your battery shows as 3.2V,the battery will be LiFePo4.If the normal voltage of your battery shows as 3.6V or 3.7V, the battery will be Li-ion or Li-polymer battery. you can also ask battery manufacturer the material of battery.

Q: Can I use this protection circuit board for my battery?
A: Can use this protection circuit board, or not?
There are 2 questions:
How much cells in series is your battery pack?
The protection circuit board you need to buy must be same cells in series as your battery pack.

Q: What material is your battery?
A:Only the LiFePo4 battery has different electric parameter from other battery, so if you need buy the protection circuit board for LiFePo4 battery , Please let us know firstly.

Q: Do we need cell balance or not?
A: The function of balance : Since battery is made of many pcs of cells in parallel and in series, the cells can't be the same as no two people in the world is the same , so can only put in group with similar performance is not without balance function

Q: Do you have Minimum Order Requirement (MOQ)?
A: No, We don't have MOQ, Different customer have different requirement ,We can provide various capacity and size as per your requirements,Also ODM / OEM is welcome.

About your products, just tell us the relative voltage/ cells/ current A or equipment etc,we will help to recommend the most suitable products for you.
