No idea on sizing but I think two 100AH BattleBorn... or DIY CALB, Sinopoly etc. would fit with plenty of room left?Battery Musings..... Why can mfg's stick to regular sizes.
Same dimensions basically, but more amps and $$ with FR.
Trojan 105AGM, 217AH $916 avail locally.
Fullriver 250-6 250AH (what I have now) $1469 shipped
Lifeline GPL-4CT, 220AH, $1463, avail locally.
These are 2.3" longer, I may not have the room for them....
Victron BAT406225084, 240AH $1047 avail locally
That is thinking of sticking with 6V's. Any other's I should look at?
As much as I don't like the BattleBorn price they are hard to beat for a drop in.
I know that doesn't help you... 4 of the $99 6v GC2 batteries is a awesome bank for the price but is super heavy and takes up allot of real estate.
If you are limited by internal venting issues and restricted size, lithium would be my choice. I am a tight ass so I would go for china shipped modules or used automotive i.e. Nissan Leaf? modules with BattleBorn as a last resort. I kind of barfed the %30 tax credit on "solar" installs for 2019 that would have likely paid for the battery due to the installation costs being so high.:smokin:
