I have just discussed this non-start issue with our engineer and he confirmed there are some compatibility problems with some "smart" chargers, which mentioned MeanWell is. It works fine with usual CCCV power supplies, but smarter devices sometimes struggle, as we get two smart devices toggling each other and missing the window to turn on.
Do you have any firmware update for the charging detection?
Here some details how MeanWell smart charger detects/check the battery pack. (Example is given for 12V battery pack)
"Initial stage (battery analysis)： If the detected voltage level is within the range of 5~13.2V then charging will commence. If the battery is not connected (<5V) or it is already full (>13.2V), no charge will be provided. If the voltage is within normal range, pulse current will be provided to determine whether or not the battery is OK. Pulse current level <10A will be considered as faulty."
