New Type Red 8S20A PCM/BMS for 24V/8S Lifepo4 battery pack Description:

As we know, without PCM/BMS, the battery pack is easy to over charge and over discharge. 

Here A123rc.com will release this kind of good-quality and competitive price PCM/BMS 

which can protect your battery pack whose constant discharging current is 20and max charging current is 5A.

 Whats more, New Type Red 8S20A PCM/BMS not only can protect the whole the battery, but also has a balance function.





As my experience, a lot of customers bought this kind of PCM/BMS, but they dont know how to connect it to the battery pack correctly.

Thus, Lets learn to how to connect this PCM/BMS. Check photo and the following 8S connection way.




8SBMS Connection Way

1.Plug the balancing wire connector into the BMS, you will see the BMS marked as B+, B7,B6,B5...B1, B-.

2.Please find the general positive end of YOUR battery pack, and connect the B+ wire to the Your battery pack's general positive end.

3.Connect the B7 wire to the joint of the first cell(negative) and second cell(positve)

4.Connect the B6wire to the joint of the second cell(negative) and the third cell(positive)

5.Follow the above way untill you connect the B1 wire to the joint of the seventh cell(negative) and eighth cell(postive)

6.The eighth cell's negative end is the general negative end, which should be connected to the B- position on the BMS with an extra wire

7.You also need to use wires to connect P- and C- from the BMS

P- : You need to connect a black wire to the "P-" of BMS, and the other red wire will be connected   to the battery's general positive end,

       these two wires will be one pair of discharge wires, which should be connected to your controller or any other load.

      This pair of wire must be strong enough to support the discharge current.

C- (CH-) : You need to connect a black wire on the "C-" of BMS , and  the other red wire will be connected to the battery's general positive end, 

                 these two wires will be one pair of charge wire, which should be connected to your charger.
