Thanks for the reply! I had the trailer plugged in via a 110 adapter for at least a day so I thought that would be long enough to charge them up but I didn’t put a volt meter on them. I usually only have one of the overhead lights on for 20-30 minutes at a time, I don’t turn them all on all evening. Only when I absolutely need one. I totally get that the heater could be taking a lot, but I didn’t think enough to drain these bigger batteries. Maybe I should do a proper load test on them.
