LWS is a famous LI-ion BMS 1S 2A 3.7V Lithium Battery Management System with NTC manufacturers and suppliers in China. We are proud of the products made in China. Our products are both customized and high quality. Besides, we have our own brands and we also have CE certification. You can buy LI-ion BMS 1S 2A 3.7V Lithium Battery Management System with NTC with reasonable price from our factory. If you are interested in our products, we will provide you price list and quotation.


First step: connect the B-to the battery negative terminal (the B-needs to be welded the stub first).and then connect the cables (before connecting the cablesremove the cables from the bms)

Second step: start wiring from B-B-is connected to the battery total negative terminal(will say this name to number 1 ). The sideline B1 is connected to the positive of number 1 battery.the third line B2 is connected to the positive of number 2 batterv.the fourth line B3 is connected tothe positive of number 3 battery and so on.

Third step: After the cables wired,test the voltage what between each two adjacent lines from the first one,the voltage of Li-ion battery should be less than 4Vthe voltage of LFP battery should be less than 3.5V.After checking.insert the line.

Fourth step: And then connect the negative terminal of charger and of load to P-/C-B-and P-/C- should be wiring with bold cableThe wiring method requires the order must to be correct.

 






 

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.
