Smart BMS Battery Description:

Battery protection board, as the name suggests, lithium battery protection board is mainly an integrated circuit board that protects rechargeable batteries (usually lithium batteries). The reason why lithium batteries (rechargeable) need protection is determined by their own characteristics. Because the material of the lithium battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short-circuited, or ultra-high temperature charge and discharge. The three basic functions of the lithium battery protection board are short circuit protection, overcharge protection and overdischarge protection.

RFQ

1.What is the common port and separate port? what is the difference?
We take 13S 48V 15A BMS as an example, common port 15A 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 15A. 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 15A, 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, LifePo4 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 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, LifePo4 3.6V)are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage (Li-ion 4.25V, LifePo4 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

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 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.

4. What type of charger should I choose?
Lithium battery must choose specific charger, do not use Charger for Lead acid battery, for lead acid 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.

5. What current BMS should I choose ?
Take 10S 36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of controller. eg., choose 15A for below 350W, 20A for below 500W, 30A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one in all, continue current shall be higher than current limitation in Controller.

6. Whether my BMS damaged?
if you want to judge if the BMS is damaged, please take the following 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 displayed as no charge, no discharge, no discharge while the battery has voltage.
