LiFePO4 Upgrade coming

I am looking to upgrade to LiFePO4 this spring. I have a 2021 Bullet Ultralite 258RKS. When connected to shore power will the existing charge controller fully charge the lithium batteries or is it just designed for lead?

If lead only what is the recommended replacement charger and how difficult to install?

Sorry if previously asked/answered. Searched the forums but didnít find the answer.

Welcome to the forum from a neighbor to the south. It will depend on your converter/charger model. Some can do both and will “learn” what you have. But you need to confirm what you have to know.

The WFCO converter in a 2021 will charge the LifePo4 batteries to around 80-90%. That isn't necessarily a bad thing, if you have solar it could then top them off. For a new compatible converter give them a call at Best Converter.
