A: It depends on your load power such as electric motor powerpleasecontact the sales or technical support before buying.
A: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same portwiring and the charging current is equal to the discharge current.
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.
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
A: Always a pre-production sample before mass production; Always final Inspection before shipment;
