Lithium Battery

[Midnight Rider]

I just installed the LiTime 165Ah and needed to cut off the original battery terminals and crimp on some M8 (5/16") Lugs. Just a heads up.
At the time of purchase LiTime had it on sale for $390.
I had 6AWG wire but one day I'd like to upgrade at least the feed from the battery, and cutoff switch to 4AWG.

So the old cables are two big for the posts on the lithiums?

Yes my cables had ⅜"/M10 ring terminals and the LiTime needed M8. Close but no cigar. The ring terminals I linked are also of much superior quality to the thin ones on the original cables

Flyer,
When I upgraded to the lithium, all I did was flip the switch on the converter and changed the profile on yhe solar controller. We been running it for 2 years without issue and get most of the full AH use of the battery. Lithium is the way to go.

Good luck,Did you have to upgrade your

When you upgraded batteries did you have to change cables like George did below?

To clarify... The two FLA batteries I replaced were in a plastic battery box. Both FLA batteries have 5/16" terminals. They were connected parallel inside the box and the dealer used ⅜" ring terminals. So I guess I didn't HAVE to change them. They obviously worked okay with miss-sized terminals. But I couldn't abide that. 🙃
The box has ⅜" feed thru terminals on it so the coach cables with ⅜" ring terminals worked fine there.
I did not use the battery box. I removed it and put in a ¾" plywood floor with an old piece of Formica underneath for water protection.

Rider,
No i did not. My battery bolts matched up with the stock ends on the cables.
Good luck,

As long as cables fit over post it should work fine? Know soon enough?

You can see my current system. Standard nut style battery posts.

I wouldn't say "As long as cables fit over post". You can probably get away with it but it'd be better if you're able to crimp on the correct size. Hydraulic Crimper , or Crimper or Hammer Type or use a vice like a Youtuber I saw doing yesterday 🙄 not.

Exactly the same Grp 24 batteries that I had. It looks like your dealer used the correct terminals inside the box. I suspect the coach cables from the battery box are ⅜" ring terminals, since they're connected to the feed thru's on the box..

---

I should have added that the main reason I didn't re-use the plastic battery box was that it was cracked and I'd already added a plumbers tape strap underneath it to hold up the FLA's.

One more — You won't need the vent hose anymore with Lithium(s). I wonder if Alliance still cuts the louvered hole in the front for it with a Super Solar Plus package? 🤔

---

Well, two — I realized I'll need some 6awg/#10 ring terminals for the busbar at some point. (later cable upgrade to 4awg) I should have bought the #10's in the first place and drilled them out to 5/16" or whatever other size I might need in the future. As long as they're wide enough. It's much harder to make a hole smaller.😉

Agree...no longer needed.

I put a 12v fan over the existing hole that is heat controlled. It will now come on automatically when the battery compartment gets too hot and will push out hot air.

thanks,

im leaving all my wiring as it is just putting in lithium. Are my batteries in tandem?

Rider,
Hook them up in parallel. Just like they are now. Positives to Positives and negatives to negatives.
Good luck,

 

[George]

As 2 Allies said (Parallel) but also when you connect the RV cables...
NEG to Battery #1 and POS to Battery #2
As I understand this is more important for lithium than lead acid.

Got it!
just going to put them in just like the LA’s I am replacing.
hook it all up and smell for smoke? 🙈
