Imagine 21BHE Battery Upgrade - Lead/Acid to Lithium
I just ordered 2021 Imagine 21BHE that should arrive in middle of march and I am already thinking of performing the battery upgrade. For now I am just thinking of replacing the Lead/Acid batteries that come with the unit with two BattleBorn 100Amp 12V Lithiums. Is it OK just to swap the batteries for now or do I need to replace some additional components. I understand that the 21BHE comes with WFCO WF-8735 power center that is not necessarily made for Lithium battery charging. I know they do have the WF-8735Lis available but I don't want to spend the money now if not necessary since in the future I planning solar upgrade and I think that this power center will get replaced anyway. For now the assumption is that I will charge from shore power only until solar upgrade. Any suggestions will be appreciated.

If you drop in Lithium's, you will be much happier upgrading the converter to a lithium capable converter. The lithium capable converter will ensure your Lithium are charged at the correct voltage consistently and in a timely fashion.

I think the 22MLE factory installed WFCO 8735P has the converter "built-in" so I am curious how you would disable the built-in converter and install a stand-alone converter. On my 22MLE the converter and Water Heater are on the same breaker too. If you do swap out it out, please do a good write-up with lots of pics, as I am sure others like myself would be interested in the steps.

I found one option from Progressive Dynamic that might fit the opening. It has the higher current rating but I think it should be OK.

I am planning a battery upgrade on my 21BHE. Getting rid of stock provided led acid battery and replacing it with two lithium 100AH ones. Attached is my initial diagram on what I am planning to do. Any additional suggestions or corrections. Also I am not sure how the 7 Way Trailer Connector plays into the picture. Is the Aux 12V coming from the connector directly connected to existing battery or is it going through the panel. Thank you

Thanks for your diagram. Looks good to me.
Haven't pulled the trigger yet, but here's info I have so far: WFCO has advised me that they have a direct replacement power center/charger - model #WF-8735PB-Lis that has a switch built in for lithium charging. Not sure if it is yet available but Camping World has quoted me $159 (w/membership); available in early April. I checked with Progressive Dynamics and they have a direct replacement - model #PD4135KW2BV , which is available at Leisuretime Distr. (ltdrvparts.com) for $149. Sounds like that one is a good option. I'll be making a decision very soon so I can get setup for the season.
I'm trying to decide whether to mount the lithium battery(s) on the tongue or inside the pass thru storage. I need to mount a solar connection so I can use my "suitcase" panels for charging. A solar connection would have been nice to have on these smaller models.Dennis & Lydia

Revisiting this thread to see if anyone has successfully resolved the built in converter issue with these WFCO power center/converter units? I've had my lithium batteries in my little 17MKE for a month now and they are staying fully charged from the solar but I can envision the day when I won't have full sun and need to charge via a generator or shore power and would certainly like a lithium rated converter/charger.
What I would really like to do is just disconnect the built in converter from the power center and wire in a stand alone PD lithium converter but next choice would be to replace the 8735 with either the WFCO lithium version (WF 8735 Lis) or the PD4135KW2BV.
So, has anyone actually done this upgrade yet?
TIA
