ID Switch indicates the unique ID code for each battery module. It's required to assign an identical ID to each
battery module for normal operation. We can set up the ID code for each battery module by rotating the PIN
number on the ID switch. From number 0 to 9, the number can be random; no particular order. Maximum 10
battery modules can be operated in parallel.
