4. Preguntas más frecuentes
q: ¿Cuántas placas de circuito de protección de amperios debería elegir??
A: Depende de la potencia de su carga, como la potencia del motor eléctrico, comuníquese con el servicio de ventas o soporte técnico antes de comprar..
q: What is the distinction between same port wiring and different port wiring?
A: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same port wiring and the charging current is equal to the discharge current.
q: What is the distinction between balance and unbalance function?
A: Equilibrium function is that high voltage cells will be discharged with resistor, waiting for the low voltage cells , to achieve the each cell voltage is consistent , to improve the battery performance for the whole group.
q: Do you have Minimum Order Requirement (MOQ)?
A: No, We don’t have MOQ, Different customer have different requirement ,We can provide various capacity and size is per your requirements,Also ODM / OEM is welcome.
q: What is your term of payment?
A: PayPal, T/T, carta de crédito,
About your products,just tell us the relative voltage/ cells/ current A or equipment etc,The right bms details will be shared .
