Product Q&A
Q:How to choose the suitable BMS?
A:
Please provide the battery type (3.7V Li-ion or 3.2V LiFePO4), number of series cells, peak power watt of load/motor, and intended application.
Q:How to activate the BMS?
A:
Activation methods include: 1) Using the activation switch on the power board; 2) Pressing the button on the Bluetooth module; 3) Charging activation by connecting the B-line to the total negative pole.
Q:What is the balance function and do we need it?
A:
The balance function starts when cell voltage reaches the balance threshold (3.6V for LiFePO4), discharging at 35mA to equalize voltage. It stops charging if over-voltage is detected. If voltage differences are large, replacing cells may be necessary.
Q:What type of charger should I choose?
A:
Use specific lithium battery chargers. For LiFePO4, voltage equals series count x 3.6V; for Li-ion, series count x 4.2V. Do not use lead-acid chargers as they may lack proper protection.
Q:Do you have a Minimum Order Requirement (MOQ)?
A:
No, we do not have an MOQ. We accept orders starting from 1 PCS and can provide various capacities and sizes based on your requirements.
