Been eyeballing for a long time..... Install weekend after next. Batteries should be here by then hopefully.

I had the lid off already. Its beefy.

Going to suck to try to get it in place in my rig, but such is life!

Java Electrical upgrades inbound.

New inverter charger. Had to go with the 3kw as the 2kw that I wanted is the "compact" model and 6" taller.... New control panel for all the Victron stuff to talk to each other.


Since I was planning 2kw not 3kw, all my connections are undersized..... All new connection goodies for 400A. The inverter is set up to run dual 1/0 cables for pos and neg. Not quite sure how its all going to fit..... Fingers Crossed.

Ha!

Talked with the wife. She said order the same ones. So I did. 10 years is a damn good run

2"EPS foam would be easy, again not really sure on how much room you have.

@ 40* you only have 87% capacity.

Yep I saw that too.... Its not warm under the bed. Better than outside, but chilly. Beer doesn't freeze, but doesn't need much time in the fridge to drink either

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.
My issue with the lithium is they can't be charged under about 40 degrees. That doesn't work well for me for half the year..... And heating them with their own power seems silly (i don't have a way to duct heat there).

Trojan 105AGM, 217AH $916 avail locally.

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?

I have heard the Victron BMV and others don't account for Peukert effects as well as we might hope so a .00 decimal reading volt gauge and a SOC chart is a better gauge of charge.

How accurate is the gauge in the switch panel compared to the BMV?
The similar unit I put in my wifes SXS is .2v high.
Shunt is rated at .4% accuracy for amperage, so not perfect to begin with.

The BMV does take Peukert effects into account. Its using 1.25 at the exponent for lead acid batteries.

I didn't even think to check the voltage on the Victron....

I did find some interesting tidbits in the manual. This could be why the percentage was so wonky last time, The little bit of charging from running the truck or a little solar probably reset it.

It was a fun challenging afternoon on that road. Had to turn 180 degrees around at one point....

Stevens pass has an "RV Lot" they charge, but have hook ups. Its pretty slick. Pretty much as close as you can park to the main area, and can ski right back to the truck through the woods above the lot.

Uhhhh its only down there because I broke it off on some tree branches..... And it seems you can't get parts from Wilson, only a whole new antenna kit (with spring now.... ) for like $70. I have not wanted to spend the $$ yet.

Yes the big OTR antenna works much better than the little mag mount. I have both. But you should look at a directional, they are supposed to be even better, but take some set up/aiming.

This is the road that claimed the antenna. At least just the CF tube broke I guess. I got tight....
