The following regular maintenance should be implemented before each operation:

Check functionality of the gauges before putting them into well. You can run
a bench test to check if the gauges are in good condition. Or, use the
Diagnostics function by SmartView software to check your gauges (See 4.3

Check voltage of battery packs by a PPS battery tester (See 4.5).
The lowest required voltage of single cell battery pack is 3.2V; for dual
cells battery packs, the lowest voltage of battery is 2.6V.
Clean the threads and check for any damage;
