Easy fix... if you live in it your MH is unlikely to ever go below 0 as you’re bound to be using heating (ours is a $250 diesel heater)

If you park it up over winter, just ensure your battery is charged between 20-80% and disconnect it (or setup a killswitch like I have) as lifepo don’t lose charge over time like lead acid, and can ‘sit’ almost indefinitely at any temp without damage :TU

Just catching up with a few posts on here.

Interesting about charging at 0 degrees.
We have AGM, and they are mounted outside under the van, in fresh air!!

So when/if we change to lithium that will me shifting the batteries.
A good heads up.

Very interesting to see this on my iPhone recently:

Makes me wonder how good it is to keep our Lipo4 batteries ‘full’ all day in summer, and wether it might be worth changing the float parameter to 80-90% over summer... especially for those with lots of leeway on their overnight use...?

from above ; 'So when/if we change to lithium that will me shifting the batteries.

I have EpeverTracer -AN series 20 Amp. controller. 150W panel.
It states in the Tech spec's= 4 "when a Lithium-ion battery is used the system voltage can't be identified automatically."

To replace the 12v. AGM's with a 12v. Lithium -ion , where can I find the needed info?

My 40A is also a Tracer AN and all I did was connect the batteries first and it did fine?

They sit at 26v (+/-0.8) so fit well within the 24v nominal spec (my AGM float is 26.6v too) so I can’t see why that would be a problem?

I did have to set a customised charge profile, but basically that’s just to turn off the equalisation stage, and then set the float and boost charge appropriately :TU

Thanz . will I also need to connect a temp prob. on the Lithium battery as mine will be a 12v. system if that makes any difference ?.

What is "I did have to set a customised charge profile"
and how can I do this.?

Are there more pages for these Tracer AN Solar Controllers available?

Not needed. I used my MT50 remote monitor to tweak the charge profile. Once you pick “User” as the profile, it lets you set specific voltages for each stage, in 0.1V increments.
