Why we need the BMS board for the battery ????
Battery protection board, as the name implies, lithium battery protection board is mainly an integrated circuit board that protects rechargeable (usually lithium batteries).
determined by its own characteristics. Because the material of the lithium battery itself determines that it cannot be
overcharged, over-discharged, over-current, short-circuited, and ultra-high temperature charging and discharging,
The three basic functions of the lithium battery protection board are
short-circuit protection, Overcharge protection and over-discharge protection.
short-circuit protection, Overcharge protection and over-discharge protection.
Everyone can understand the significance of the BMS board to the lithium battery..

10. Whether my BMS damaged?
if you want to judge if the BMS is damaged, please take the folowing steps, to test if each cell voltage is the same with
voltmeter? if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the
start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displyed as no charge, no
discharge, no discharge while the battery has voltage.

5.What is the common port and separate port? what is the difference?
We take 13S48V16A BMS as an example, common 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.
6.What is the balance function?
The working principle and function are as followings, when your one cell voltage is upto alarm voltage(Li-ion upto 4.18V, Life Po4 upto (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will starts 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 stop 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 balance can not be functioning.well
7.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 rely on
continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery
capacity.
8. What type of charger should I choose?
Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge. Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
9. What current BMS should I choose ?
Take 10S36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of controller. eg., choose 16A for below 350W, 25A for below 500W, 35A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one inall, continue current shall be higher than current limitation in Controller.
