Questions & Answers

Have a Question?

Ask a Question
  • Why is 4 the maximum number of batteries that can be connected together to create 48 volts? I need 6 batteries for my 72 volt golf cart.

    Due to the limitation of the withstand voltage value of the graphite tube of the battery BMS protection board, our batteries can only support up to 48v systems, excessive voltage may cause damage to the BMS protection board.
