Well on my truck the batteries and inverters are mounted in the drom box, and I would have never found this post in the technical section so post away please.

That's fine if this is about a truck, which is why I asked, but got no answer.

To elaborate, I don't peruse this forum via any of the separate categories. I have all recent posts showing when I'm back here to look around. That way, I see what's happening in all categories. I usually forget to even check which category a post is in. Jay

In the interest of derailing even further, but bringing the HDT angle in.....Our truck batteries are 7 years old, and sometimes after sitting for a couple months, the truck cranks slowly.  No maintainer or charger of any kind is used.

So, if I determine these batteries have neared the end of their tenure here, should I consider flooded lead acid, AGM, or is there a better solution?

And I know, a solar charger would likely get me another year or two out of them, but at what price?

Personally, I wouldn't get all fancy with this. I would run down to your local Volvo, etc. dealer and just pick up another set. The low price of that option makes the other options look really unattractive. Jay

Understood, but an installation in a truck is going to be quite a bit different from an RV.  If it's in this forum, is it understood it's about a truck?

I use a couple of 50W panels for various vehicles I have.  I spent around $100 for each.  It helps to compensate for my bad memory to charge this truck or that trailer esp in my yard where I have no 120VAC.  I can leave them on there and if I forget, it isnt a big deal with a charge controller.  It also helps with fantom loads.

I have an installation in both truck and fiver. For me, the electrical design and install are essentially the same, but of course the physical details will be different.

"is it understood it's about a truck?" I would say the usual "maybe". In watching this, or any forum, the threads often drift far, far afield. That's completely okay with me, but I can see where not everyone cares for that.

Pulled the trigger on 6 battleborns 100AH batteries. With Black Friday, Coupon Discount Code, Free shipping and no sales tax, total was $4839.3 ($806.5 per battery)!! Heck of a lot less than I originally expected to pay.  hemsteadc -This big weight difference will decrease the pin weight off the HTD hitch. 

More HDT info for Rickeieio: Bought https://www.amazon.com/gp/product/B07WYP4H6W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, a 30W solar panel with controller and battery clips.  When I unhitch, I connect to the battery post and lay the panel where it will get sun.  Keeps the batteries topped off during long periods at campgrounds or boondocking...$63 on Amazon.

Thanks for the replies.  I've been contemplating a solar charger and just haven't pulled the trigger.

We're considering pulling out six year old FullRiver 400AH 6 volt AG batteries and replacing with BattleBorn 100AH Lithium's.  Any input on the below questions is appreciated:

1.  My current 6 AGMs give us 1200AH (600 usable).  I'm thinking six 100AH Lithium's will give us the same usable amps, right?  

2.  Should be plug and play, after adjusting the charging data in the controller, right?

3.  Any thoughts on how much the six year old batteries have degraded, they haven't been used hard except the last year.

Thanks in advance for any feedback!

If you are talking about adjusting the solar controller, yes, but you will also have to adjust your converter or inverter/charger profile, and if you charge off the trucks alternator, you might need a B-B charger.

Retired when Covid hit and started our cross country adventure, so no more paid trips to Norfolk!    Full Time HDT & New Horizon (wordpress.com)   Skipped Norfolk (you and my roommate from school), as we had a wedding to get to.  Next year, looking at a slower pace and may head up that way after the national rally in April.
