Upgrading my House Batteries

Thanks.

Typically a battery used to crank has a cranking anp spec. And With enough lithium batteries you could get the needed cranking amps

So how does an EV manage excess loads? Well the "way", to handle regen, and acceleration is to include a supper capacitor! This moderate investment can drastically reduce the battery bank requirements!!! Note that this will not change the required AH to make it to the next charge cycle.

Let me put it this way, he has almost twice as much invested in his solar system as I paid for my first home.

Okay now, that didn't include "solar" so you have to deduct the price of your Big Wheel.

Clodhopper, I replaced my 8 6v batteries last January with three 206 amp hour SOK heated bluetooth batteries. I lowered my battery weight by almost 400#. My magnum 2812 would come on and recharge the batteries every six to seven days when plugged in in the barn. You do need to "close up" your battery bay to keep moisture out. My generator starts just fine off of the house batteries. I just recently removed one of the batteries and the genny still starts fine. You will need to change the settings in the 2812 and probably be happier if you get an ARC-50 to replace the RC-50(plug and play)

Thanks, guys.
1. Wire in series or parallel?
2. What about cabling?
3. @Neal, do you have 4 - 300 ah batteries?
4. I've watched several of Will Prowse YouTube videos and reviews of different brand batteries.
5. Did you make your cables? @Richpatty , I live in the San Antonio area and since 2007 and have never been to an area where I needed to winterize.
6. This past year we did considerable boondocking and plan to do similar this next year.
7. I need to confirm my Mangum MS2812 is compatible with lithium charging.

Your house batteries are 6 volt, so they are wired in series/parallel to create a 12 volt "battery bank". LiFePO4's thatbyou will be looking at are going to be 12 volt - so wiring in parallel.

I'm curious how you sealed up your battery compartment. I swapped out my 8 6V for one 460 ah lithium last week but didn't have anything on hand to seal up the compartment. I had originally thought I'd use foam board insulation board but the walls aren't nice flat panels - there are lots of brackets, bolts, and other protrusions that keeps anything from laying flat against the walls. I'm thinking of using something like a thin rubber membrane. Maybe the membrane you lay down before tiling a shower.
