@RandyDaytona I used a group 31 for the deep reserve capacity, but that was probably overkill for my little ARB 37 quart.
Yes, these travel fridges are very efficient. IIRC, the compressor on my fridge pulls around ~2amps when cycling. And keep in mind, that’s only when it was running. The power consumption is near zero when the fridge is in standby mode (maintaining the desired temp). I would imagine, like ARB, your Norcold has a low voltage cutoff as well, which further protects the battery.
