Frequently Asked Questions
Q: How many Ampere protection circuit boards should I choose?
A: It depends on your load power, such as electric motor power. Please consult technical support regarding your specific equipment needs before purchasing.
Q: What is the distinction between same port wiring and different port wiring?
A: In different port wiring, the cathode of the charger and the load are separate. In same port wiring, they are the same, and the charging current equals the discharge current.
Q: What is the distinction between balance and unbalance function?
A: The equilibrium (balance) function discharges high voltage cells through a resistor to match low voltage cells, ensuring consistent voltage across the entire group for better performance.
Q: Do you have a Minimum Order Requirement (MOQ)?
A: No, we do not have a strict MOQ. We can provide various capacities and sizes based on your specific requirements. OEM/ODM services are also welcome.
Q: What are the main protection functions of this BMS?
A: The BMS provides comprehensive protection against over-charge, over-discharge, over-current, and short-circuits, as well as temperature monitoring and voltage balancing.
Q: What payment terms are accepted?
A: We accept multiple payment methods including PayPal, T/T, and L/C for your convenience.
