Another option for LFP I’ve recently come across is Sun Fun kits dot com… also there’s apparently a private seller in Minnesota that offers what appears to be home made LFP batteries that seem reasonably priced as well (which notes it allows for replacement of cells if needed in the future) https://www.tesselectric.com/product/12v-100ah-battery/ *** I have not personally bought yet from either one, as we are not sure yet what amount of LFP we need to purchase. We need a traditional dimension battery as it’s going to be a drop in replacement in an AF990 TC; If we determine we need more than 200 amp hours for batteries we will probably go with the sun fun kit battery; otherwise we may purchase from the smaller private seller Tess electric - Just sharing as an FYI for others to do their own due diligence on researching if it’s worth the chance to go with new or private sellers 😉
*PS-If anyone else has gotten batteries from these 2 companies, I’d love to get your feedback on them as well!
