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.
