FAQ
Q: How do I know what material OR type my battery is ?
A: Please look the battery body,if the normal voltage of your
battery shows 3.2V,the battery is LiFePo4.If the normal voltage of your
battery shows 3.6V or 3.7V, the battery is Li-ion or Li-polymer
battery, You can also ask battery manufacturer for the material of battery.
Q: Is this BMS suit for
my battery?
A: This BMS suit your battery or not depends on below
2 points:
How many series you cell is in your battery pack? The BMS you
buy must be same series as your battery pack.
What material your battery is? Only the LiFePo4 battery has
different electric parameter from other battery, so if you need buy the BMS
for LiFePo4, Please let us know firstly.
Q: What is the Common port and Separate port? what is the
difference?
A: We take 13S 48V16A BMS as 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 same as 16A.
Separate port is separately connected by charge cathode (our
C-) and discharge cathode (our P-), so the charge current and discharge
current are different, discharge current is 16A, charge current is 8A.
Q: What is the balance function?Do we need cell balance or
not?
A: The working principle and function are as followings:
When your one cell voltage was reached balance
voltage(Li-ion 4.18V, LifePo4 3.6V), that cell balance start work, balance
resistance starts discharge with 35mA, that cell was in both charging and
discharging status, and other cells were not reached balance voltage(Li-ion
4.18V, Life Po43.6V), so they are only in charging status, when the fast
cell voltage was reached overcharge voltage (Li-ion 4.25V, Life
Po4 3.75V),BMS starts off power protection, all the cells are stop charging,
this process will enable your battery charging in balance current, and your
battery voltage are in balance status.
However, if your cell voltage difference are in a big range,
The equilibrium effect is almost zero,The solution is to replace cells with
large voltage gaps.
Q: The relationship between battery capacity(AH or mAH) and
BMS current(A)?
A:There is no direct relationship between battery capacity and BMS current,
big capacity doesn't mean big current, but rely on continue current, that is
to say if your engine is powerful, you should choose high current of BMS, it
is not relied on battery capacity.
Q: What type of charger should i choose?
A: Lithium battery must choose specific charger, don't use charger for
leadacid battery, for leadacid charger may have MOS with high pressure
breakdown protection, which will not protect of BMS over charge. LiFePo4
battery charger voltage = number of battery strings X 3.6V, while Li-ion
battery charger voltage = number of battery strings X 4.2V.
Q: What current BMS should I choose ?
A: Take 10S 36V as example:
What current BMS you choose is depend on your E-bicycle motor
power and current limitation of controller,eg.16A for 350W and below, 25A
for 500W and below, 35A for 800W and below, 60A for 1000W and below, over
1200W are contact with our service specialist for suggestion, continue
current shall be higher than current limitation in controller.
Q: Do you have Minimum Order Requirement (MOQ)?
A: No, we don't have MOQ. different customer have different requirement ,we
can provide various capacity and size as per your requirements, also ODM
/ OEM is welcome.
Q: How to contact for BMS?
A: Please send messages at below or E-mail us and
we are always glad to help you with BMS.
