1. Verbind eerst de B- van de BMS naar de totale negatieve pool van de batterijpakket;
2.De kabel begint vanaf de dunne zwarte die B-, De tweede rode draad verbindt de positieve pool van de eerste reeks batterijen, en de volgende string is op zijn beurt verbonden met een positieve pool van de batterij,B-, B1, B2……B4; Plaats vervolgens de kabel in de BMS;
(Het maximale aantal snaren is 4 strijkers, De voorbeeldfoto is 3-4 strijkers) (Las de draden in volgorde en vermijd pseudo -soldeerverbindingen.)3. Verbind oplader C-/Load P- met BMS C-/P- (Gebruik grotere draden) 4. Verbind positieve pool: Lader C+/Load P+ met batterij B+ (Gebruik grotere draden) .

3. FAQ
|
Q: How many Ampere protection circuit boards should choose? A: It depends on your load power such as electric motor power please contact the sales or technical support before buying. 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: Heeft u minimale bestelvereiste (MOQ)? A: Nee, We hebben geen moq, Verschillende klant hebben een andere vereiste ,We can provide various capacity and size is per your requirements,Ook ODM / OEM is welkom. Q: Wat is uw betalingstermijn? A: PayPal, T/T, |
