I asked Odyssey about this. They said " do not have the their charger on the battery at the same time that you are using the battery". Something to do with how the Odyssey charger reads required charge. So, work on panel from battery, then recharge.
Personally, I bought a dedicated 13.8 volt, 40 amp power supply. Disconnect the battery cables and powered from that supply source. Powers everything all day long and no second guessing amount of charge left or other battery issues. Plus, power supply comes in handy for dry rub testing stuff on the bench.
