12S 20A lifepo4 BMS

It can use for less series: If you by 8S, then it can use for 3S~8S. 

This is for less series connection picture

Note:

1. The BMS only support change to less series(Such as 16S BMS, it can use for 3S~16S, Mustn't for 17S). The minimum

support is 3S (3 Strings battery packs)

2. The above Picture is connection method. For the circuit design , Must use our Wires to connection.

3. Not every BMS support changing the number of strings. The integration circuit and software board do not support changing the number of strings.

4. Connection method: Starting from BC0, BC0 is connecting to the total negative terminal of the battery(B-), the second wire of BC1 is connecting to

the first positive terminal, and the third wire of BC2 is connecting to the second positive terminal BC3,The fourth wire is connecting to the third battery

positive pole. And so on, and the empty wire All connecting to the total positive pole of the battery(B+).

Q : What is balancing function?

A :Working principle and function: when the battery voltage has a series to reach the voltage of

balance open voltage of (lithium)4.18 V /(lifepo4)3.58 V(Need according the specification), the

balance of the section on protection board will automatically open, balanced protection board after

open a well balanced resistance will with 42 mA to discharge (when the balance start the discharge,

protecting plate back there will be a slight heat, this is normal reaction) and then Charge and discharge

simultaneously, other section voltage didn't reach balance open voltage of 4.18 V / 3.58 V, is charged

only, then the highest section to overcharge protection voltage will be power-off protection, other batteries

will be stop charging.This working principle can make the battery charge in balance, so that the battery

voltage balance effect, but if the battery voltage gap is large, then the function of balance function is basically   no have.

Q : Relationship between battery capacity and current of BMS

A :There is no direct relationship between the battery capacity and the current of the BMS. That is to say, the larger   the motor, the larger the continuous current of the BMS you choose will be,

and the battery capacity is not directly related
