Product Q&A

Q:How to choose the suitable BMS?

Please provide: 1. Battery type (3.7V Li-ion or 3.2V LiFePo4); 2. Number of cells in series; 3. Peak power watt of load/motor and application type.

Q:How to activate the BMS?

Three methods: 1. Use the activation switch on the power board; 2. Press the button on the Bluetooth module; 3. Charge activation by connecting the B-line to the total negative pole.

Q:What is the balance function?

When a cell reaches balance voltage (4.18V for Li-ion, 3.6V for LiFePo4), it discharges at 35mA to balance. If voltage difference is large, replace cells with large gaps.

Q:What type of charger should I choose?

Use specific lithium chargers. LiFePo4 voltage = strings x 3.6V; Li-ion voltage = strings x 4.2V. Do not use lead-acid chargers.

Q:Do you have a Minimum Order Requirement (MOQ)?

No, we do not have an MOQ. We accept orders from 1 PCS and support various capacities, sizes, and OEM/ODM requirements.
