Battery BMS Board Description:

Wheelchair Lithium Battery BMS Board PCB BMS 24V 7S 20A 30A, our work creates a BMS that is safe enough for you. The battery BMS board has been tested and is generally used with -go°C-7oc. The high-performance aluminum alloy radiator provides strong thermal protection and reduces the temperature rise of the protection board. The battery BMS board is safer in kind, intelligently balanced, and temperature controlled, making your battery safe and stable.

Battery BMS Board FAQ:

1. What are the standard ports and separate ports? what is the difference?
We take 13S48V16A BMS as an example, joint port 16A means your charge cathode and discharge cathode are connected in the same point end(our P-), charge cathode and discharge cathode are used in the common connection port, so the charge current and discharge current are the same 16A. while the separate port is separately connected by charge cathode (C-) and discharge cathode (P-), so the charge current and discharge current are different, discharge current 16A, charge current 8A.
2. What is the balance function?
The working principle and function are as followings when your one cell voltage is up to alarm voltage(Li-ion up to 4.18V, Life Po4 up to (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will start a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po43.6V)are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage (Li-ion 4.25V, Life PO4 3.75V)BMS starts off power protection, all the other cells are all in the top of charging, this process will enable your battery charging in balance current, and your battery voltage are in balance status, but when your cell voltage difference are in a big range, then the balance can not be functioning. 
3. The relationship between Battery capacity and BMS current?
There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery but relies on continued current, that is to say, if your engine is powerful, you should choose a high current of BMS, it does not rely on battery capacity.
