Attention

 

Buyer attention:In order to confirm if our charger is suitable for your battery pack, please confirm the following issues: 

(1) What is the voltage range of your battery, which is for us to decide the right model for you.

 

(2) To use Dilong CAN communication protocol or yours?

 

(3) CAN Baud rate 250KBPS or 500KBPS?

 

(4) Adjust voltage and current through CAN Bus.

 

(5) Charger is built in 2W auxiliary power supply to active BMS, 100W is another option
