Features
This product is 14 string 48V lithium battery power protection board. With a balanced, same port 45A discharge.
The same port charge current and discharge current as large as the charge and discharge in the same positive and negative.
Note
The battery in parallel and then in series, and to ensure that the correct welding (18650 battery with nickel spot welding), do not use screws screw, easy to burn the protection board IC.
Please allow 1-2mm error due to the manual measurement.
Package includes
1 x Protection Balance Board
1 x Terminal Line
