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
Espar power drain

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.
