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 intended application.

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. Connect B-line to total negative pole during charging.

Q:What is the balance function and do we need it?

It balances cells when voltage reaches 4.18V (Li-ion) or 3.6V (LiFePO4). If voltage difference is large, replace cells with large gaps as equilibrium effect is near zero.

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 as they may damage BMS.

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

No, we do not have an MOQ. We support various capacities and sizes per requirements, and welcome ODM/OEM orders.
