FAQ

Q1:How to choose the suitable bms?

A:Pleaes tell me below 3 questions ?I will recommend suitable bms for you.

 Q1:is your battery pack 3.7v li ion or 3.2V lifepo4 ?
 Q2 :how many cells in series of your battery pack ?
 Q3 :What's the peak power watt of your load or motor ? Whar kind of application do you want to use the battery pack for?

Q2:How to active the bms?

A:For our smart bms,when first use,need to activate first,

   Activation method:
 Method 1: Purchase the power board,there is an activation switch on the board and click the button.

 Method 2: Press the buttonon the bluetooth module to activate the bms directly.

 Method 3: Charge activation, B-line must be connected to the total negative pole of the battery pack when charging

Q3: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.

Q4: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.

Q5: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.

Q6: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.
