So I have been exchanging emails with battleborn about if I changed to lithium in my 2017 Ventana. I am probably not a good candidate as I don’t boondock very much and it seems most appropriate for those who. Even better if you have solar it seems from that video
@Neal posted. I was interested in learning more so this is a condensed version of the emails.
Thanks for contacting Battle Born! We will want to check the compatibility of your rig’s charging components. Four of our 100ah 12v Battle Born batteries will be very close to the usable capacity of your current bank. Five of our batteries would increase the capacity from your current reserve.
Most Newmar’s are equipped with a BIRD and solenoid relay for alternator charging. This will need to be swapped out for a Lithium Isolator (LiBIM) in order to protect the alternator from overworking. The LiBIM is recommended if you are using 3+ Battle Born batteries.

To replace your (8) 6 volt batteries, you would need 5 of our 12v 100ah batteries.
Reasoning:
8 – 6v 225ah GC2 batteries in a series/parallel connection create a 12v 900ah bank, but with a 50% discharge floor, you have a usable 450ah reserve.
5 – 12v 100ah Battle Born batteries in parallel create a 12v 500ah bank with a 100% usable reserve.
For the Magnum inverter/charger, you should have a Magnum Remote inside of the coach. Go to Setup, Battery Type, and see if you can select the CC/CV setting, or possibly a custom setting.
FWIW.
