I have been using Lithium Ion Bat ( LIB ) packs which weight less than 5 Kg to run Compressors, Fridges, LEDs etc. for a few years.
These use XT60 / XT90 plugs, not Anderson ( AP ).
LIB packs are more about taking packs to appliance rather than wiring to APs, I have not used my dual Bat since I started using LIBs because a single LIB will pwr a fridge for approx. 24 hrs. this allows you to re-charge via a panel.
I have 2 x 350W panels on my rolux with 1x directly wired into a fridge and the other used to charge LIBs.
You can buy packs from RedArc -
