I am looking to use LiFePo4 batteries for my next build as I had a lipo fire that took out my last one. I have had a hard time finding viable sources for these batteries. This one seems quite professional and was not all in Chinese when I clicked on it so it looks pretty good to me. Has anyone had any experience with these guys? I plan to use 36 of these to create a 13s 24ah pack. Thoughts?
