Jehu Garcia 50ah 12 Volt LFP battery (Jag35), How I installed a BMS.

A Viewer asked me to show how I installed a BMS's on batteries I brought from Jehu Garcia. the Video shows a 100amp Smart Daly BMS, but when I finally put the 16 - 50amp LFP batteries together, I most likely will use 20Amp 4S 12Volt Daly BMS's on each battery whether they are in series or in parallel. Do I think these batteries are a good buy? That is very debatable, I will have to see when I finally put them together before I make my final verdict!!!
