Question LiFePO4 Upgrade to 2022 Passport 221BH

I just bought a Battle Born 12v 100ah replacement for the lead acid that came with my 221BH. I have 400w solar package and Victron Smart Solar charger (MPPT 100 30). From what I have read, I should be good to replace the battery and then change battery type to lithium in the solar controller. Am I missing any steps for this upgrade? I have found lots of info online on different sites, but, I have not been able to find out if I can just install the battery and change the Smart Solar setting and be finished with the upgrade. Am I missing anything? Many thanks for any info that you could provide!

Welcome to the forum

Your good as far as the solar controller, now you just need to check your converter to make sure its compatible with the LiPo battery.

Thanks! Researching what type of converter I have right now! I have read that some have a physical switch that needs to switched to lithium.

Your best bet is not to trust any brochure or literature. You need to access the converter and get the numbers off the actual unit and then look at a manual for THAT unit. Not all converters are created equal, especially for a trailer that was built in the “Covid era” where they often used whatever was available the day your trailer was built.

I just had to recently adjust the settings for my victron controller. These are the settings it recommended for lithium ….
