Low Battery - Heater Not Working

[Aonarch]

To clarify, truck didn't sit for two weeks, drove it every other day. Just the USB drive was in for two weeks

Which is why I think you should go ahead and grab a H8 battery before you get stranded.

The center console is the only one that is hot after turning off the ignition. It does use the BMS, so will turn off once a certain voltage floor is met.

Sounds like you drive every day and have a 35 minute commute? That is plentlyyyyy of driving to keep the battery charged.

Console under the dash?

Still on a timer?

I have to drive for at least an hour before mine is fully charged. I drive 25 minutes to work everyday and the volts stay at 15v the hole ride.
