Put together a hi-res PDF a while ago with basic dual battery system components a while ago, you can download from link on this page: Delta Vehicle Systems - 1FZ Dual Battery Kit Components - https://www.deltavs.com/all-products/1fz-dual-battery-kit-components
Please note, I am NOT trying to sway you from the Slee components, it just has the link to the PDF. Also, it is not an exhaustive component list by any means.
Gives you other things to think about too. I will be updating it soon to a three battery system: "start" which is the OEM battery, "aux" which is the second battery under the hood, and "house" which would be the third battery in the back, likely a higher tech lithium or similar.
The main and aux batteries should be combined with a large relay like the Blue Sea 7622 or similar so you can use the aux battery to jump start (can't do that through a DC-DC charger like the Redarc or equivalent Victron), then a DC-DC from aux (or main if desired) to house. In this setup, you would want the main and aux to be of similar battery chemistry since they will be getting charged the same way, then the house battery can be any chemistry since the charging of it will be controlled by the DC-DC and can be tailored to what suits it best.
AWESOME! Thanks for this.
I'm reading, reading, reading..... stay lead acid, go simple or MPPT controller and portable solar to start, or add duel lead acid..... or add odyssey.. Then I'm thinking how do i want it wired up, do it once BillyGoat.
And boom, of Couse delta has a drawing, thanks for the visual.
Currently I am leaning Blue Sea 7622, duel lead acid (costco), Victron MPPT controller ( I need to read more on the RED ARC BCDC 1225), adding portable solar with a plan to add the center hood mounted solar as well.
