Question Doubt about Solar Panels and the Lithium Battery

Hi,

We just bought our first Montana. 2022 Montana HC 335BH.

It came with a solar panel and a lithium battery. We had other trailers in the past, but never with this setup. The Solar controller is a Victron MPPT 75 / 15.

While keeping at the storage, should I turn the battery Off ? I m leaving On during the summer because the panels keeping the battery charged.

And, as I live in Colorado, should I remove this lithium battery from the trailer during the winter?

Thanks for your support.

Yes I would leave the trailer without power in storage and definitely take the lithium batt home to heat. Lithium doesn,t do well in sub freezing temps and should never be charged below 32.

I forgot to wish you a warm welcome to the forum and congratulations on your new Monty! Check out YouTube to learn how to maintain lithium batts as they are more finicky than lead acid or AGMs.

I also live in Colorado. In the winter, I keep my trailer plugged in (inside, but unheated storage) but I switch off the battery disconnect (my install) so the batteries are not charging all winter. I do not remove them. No issues yet after two winters with lithium batteries. I just have to remember to turn the switch back on before trying to move the slides or jacks; the converter does not have the juice to do it.

Thanks Scott.

I have to leave my trailer outside. My concern is if I switch off the battery, and the solar panels keep charging it, the battery could be dead soon by overcharging as it will not have a minimum source to discharged it (like the smoke detectors...).

We also live in Colorado. I left my batteries in and connected. Hit -12 over the winter without issue. I have it plugged into my 50 amp, but 15 amp will be fine. Lithium batteries aren’t damaged by the cold, they just don’t charge below freezing. If they’re Battleborn’s, they should have internal heaters.

Garymyro, not to hijack the post but perhaps your battery brand has included a BMS with cold temp monitoring and shut down. Without that feature all the experts say do not charge below freezing. Most lithiums do have that.
