Greg, the Velit 2000R Mini RV AC w/ Remote - Ductless - 6,500 Btu - 12V DC # VE69QV pulls 250-300 watts in Eco mode. So you’re looking at roughly 8–10 hours from a 200Ah 12V lithium battery, assuming you’re not running other heavy loads. That’s a good overnight buffer. In Boost mode 400–650 watts, you’ll still get several solid hours, so I'd stay in Eco mode, or at least after it cools down a bit from using Boost mode a bit.

Do you also have solar on your rig to help extend that while the sun is still out?
