Looking For Lithium Compatible Converter For 2022 Forest River Flagstaff 826RBS
Updated 10/22/2025 | Published 03/31/2025 >
Question:
I have a 2022 Forest River Flagstaff 826RBS. I recently added a Lithium battery in place of the old AGM battery. Ive read that I may need to also change the converter, but, I dont know which one I should purchase. Can you provide the best solution to purchase? Thank you in advance.

Hello Greg, sure can. I will need to know the model number on your current converter. That is the only way to look up a replacement, since RV manufacturers do not list this kind of info online. We should certainly have what you need, I just need to know what converter you are working with currently.
Leave a reply below and let me know. I am happy to get back to you.
