Thanks I will look at it and add it shortly. I have hit the word limit in the posts, making additions hard.Another option for a pre-built battery box is the ATG Bonza which are often 10% off and include free shipping:
ATG 105AH Bonza Portable Lithium Box V3 (In Stock Now)
In Stock NowIntroducing the ATG 105AH Slimline Bonza Battery Box - your ultimate companion for adventure! Designed specifically for 4WD enthusiasts, campers, boaters, and extreme sports enthusiasts, this innovative battery box is your ticket to power on the go. New Features 100A Jiabaida bms -...atgbatteryshop.com.au
I've got one of these I'm currently using to power a fridge while I'm waiting on parts to replace the secondary AGM with a lithium battery.
The ATG Bonza is using quality cells and BMS and I have personally tested it to deliver just over 100Ah of usage capacity. It doesn't include a DCDC, but does have a MPPT solar controller built-in and I can also recommend the ATG portable 225w solar panel which is currently outputting 215w into the Bonza as I'm camping.
What DC to DC charger are you using with the ATG?
