Frequently Asked Questions
How many Ampere protection circuit boards should I choose?
It depends on your load power, such as electric motor power. Please consult technical support regarding your specific equipment requirements before purchasing.
What is the distinction between same port wiring and different port wiring?
In different port wiring, the cathode of the charger and load are separate. In same port wiring, they are the same, meaning the charging current is equal to the discharge current.
What is the distinction between balance and unbalance function?
The equilibrium (balance) function allows high voltage cells to be discharged via a resistor while waiting for low voltage cells, ensuring each cell voltage remains consistent for better overall performance.
Do you have a Minimum Order Requirement (MOQ)?
No, we do not have a strict MOQ. We can provide various capacities and sizes per your requirements, and ODM/OEM projects are always welcome.
What are your terms of payment?
We accept multiple payment methods including PayPal, T/T (Telegraphic Transfer), and L/C (Letter of Credit).
Can you provide customized BMS solutions?
Yes, we specialize in custom designs. Just provide the relative voltage, cell count, continuous current, and application details, and we will design the most suitable product for you.
