【Notes on series/parallel connection】

Note 1: Battery Consistency 

Make sure all lithium batteries are consistent in terms of capacity, voltage and other parameters. If the difference is large, it is easy to cause individual batteries to be overcharged or over-discharged in use, which will affect the performance and life, and even cause safety problems.

Note 2: Voltage Equalization 

Before connecting in series for 24V/36V/48V, it is recommended to charge/discharge each group of batteries individually to the same voltage and leave it for more than 2 hours, and then confirm that the voltage is consistent before connecting the operation, to avoid the current shock and voltage unevenness.
