Just found that I had a misunderstanding about the cycle mode 6.

The MaxChgTime* is not the variable that is used during the cycle mode 6 to stop the charge due to it running too long. That is the case for regular charging, but in mode 6, we use the MaintRunTme* variable that we have been setting at 540 minutes, so some of you have been having chargers stop prematurely do to exceeding this time. R3 is the code.
The fix is to simply put the same recommended 1400 minutes into the MaintRunTme* variable.
