    Just curious as to if anyone else is running into what I’m running into. I have 3 brand new batteries. On cold nights they don’t make it through the night without the low voltage alarm going off, which comes on at 11.6 volts. This is in a flat top Pete with the curtain pulled shut so it’s not a big area. Power draw for d2 claims to be:
    8.3 amps - Start
    2.8 amps - Boost
    1.9 amps - High
    1.0 amps - Medium
    0.7 amps - Low

    good point. I do have a fridge that pulls 5 amp on occasion , but it’s only .35 kWh/24hr. 2022 389 with a cat…not sure what all runs in the background that I’m not aware of. Phone charger. Everything else gets turned off.

    There's a setting on the control panel that sets the heaters low voltage shut off level, yours is prob on 12.5 or something. With mine I use a paper clip in the tiny hole on the front which brings up change settings on the screen, then change to suit.
