2023 Micro Minnie 2100BH Lithium Upgrade?

[Hellonrotors]

I am trying to figure out if I can upgrade a 2023 2100bh to a lithium ion battery as a plug and play or if there is anything else I need to do?

Thank in advance

First, the Lithium batteries we use in our RVs are not Lithium Ion… they are a different chemistry called Lithium Iron Phosphate (LFP or LiFePO4). This is an important distinction because LFP batteries are safer and less prone to thermal runaway fires. LFPs are also cheaper than Lithium Ion batteries. You will not commonly see Lithium Ion batteries being sold for your RV.

The main thing that determines if your TT is “ready” for LFP batteries is the capability of the Converter installed in your RV. Perhaps someone with direct knowledge of the Converter installed in that model year will come along and tell you that it is or isn’t LFP capable. But you can easily determine this for yourself. Just open the door covering your circuits and fuses and look for the model number of the Converter, then look that model up and see what the specs are for your device.

I know 2024 and newer models have AD model numbers that are said to be “auto detecting” for battery types, including LFPs. I’m not positive when this started but it very well have been for 2023 model years. But now you know how to check for yourself.

I haven't made the jump yet. But in addition to the battery charger that works when you are plugged into the A/C, you have to worry about the charging from the alternator. My understanding is that with Lithium, you need to add a DC to DC converter. Otherwise, you may hurt your alternator.

I removed and replaced the lead acid battery in my 2022 2108 TB trailer with a 100 amp hour LiFePo battery. The converter automatically changed the charge cycle. You will just need to change the setting on your solar charge controller. There should be no issue with your tow vehicle alternator. You very likely have the same converter and charge controller. You should have manuals for both and should be able to get more details.
Remember never to charge one of these batteries at or below freezing. I installed mine inside the storage compartment right behind where the original battery was located. I put a quick disconnect on the battery that I use during storage.

This is super helpful, I am looking to do the same change on our 24' 2108DS. Thank you very much!
