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……B3; Plaats vervolgens de kabel in de BMS;
(Het maximale aantal snaren is 3-4 strijkers, De voorbeeldfoto is 15 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) .
