Charging Lithium batteries 2019 Intent 26M?

[Big Boo]

Hoping to replace our 2 12V 200AH lead acid batteries with at least 2 200AH Lithium Ion batteries. Does anyone know if everything will need to be replaced, or if we can use the current charging system in our Winnebago Intent 26M?

Does your inverter/charger have a remote screen and controls? If so you can use that to view the charger settings and change them to Lithium charging profile.
Most lithium batteries can be charged on the lead-acid profile but it shortens the lifespan.

Pretty sure the Intent has a Converter/Charger, not an Inverter/Charger. It does have a 1000w inverter... but it is not a charger. The Power Control Center houses the 110VAC circuit breakers and 12VDC fuses. Behind it is the 55amp charger. the WFCO Converter is located in the stairwell.

This was discussed some in the "All Intents and purposes" thread. Here's a link: https://www.winnieowners.com/forums/...ml#post3890565

It's also a bit of a chore to determine if the Converter is auto sensing for battery types. I know that brand new RVs are coming with auto sensing Converters, but it's anybody's guess on the Intent.

The now discontinued Intent was a low-cost Class A and designed to keep costs down. So, they didn't splurge on the latest and greatest components. Not that they are subpar, just that to make the model affordable they kept everything simple.

The way to know for sure is to look for the Converter model number and check with the manufacturer to see if it is LFP capable or not. And, some models can be upgraded with a small "remote" to change the charging profile.

If your Converter isn't LFP capable or if you can't add a Remote then you would need to replace the charging portion of your Converter to fully and safely charge any new LFP batteries.

And, don't forget about the alternator charging either. You should also, take care of your alternator's connection to the new batteries. LFP batteries charge differently than your current FLA Batteries. You run the very real risk of burning up your Alternator from overheating while trying to recharge depleted LFP batteries.

I did what you are going to do, but added four, (we have the same type rig), After checking with Battleborn, all I needed to do to get full charge capacity was to a a drop replacement of the WFCO charge board. Check their website for details.
