Battery BMS Board FAQ:
Q1. Do you have a current sample in stock?
A1: Most regular ones we have usually we will ship out 3 days after you paid
Q2. What's the delivery time for mass production?
A2: Usually 3-7days, it depends on the quantity, especially function and etc. we suggest checking delivery time case
by case.
Q3. OEM&ODM are available?
A3: Sure, OEM&ODM are welcome and the Logo can be customized too.
Q4. What is your MOQ?
A4: 1pc is OK. small orders are also welcome
A5: We take 13S48V16A BMS as an example, joint port 16A means your charge cathode and discharge cathode are connected in the same
point end(our P-) and 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.
