I built this 14.8V battery pack following OH8STN’s video using 4 x 3.7V 8800 mAh 26650 cells and a CF-4S30A-A Battery Management System (BMS) board. The cells are spot-welded together using nickel strips using a mini spot-welder. It will get covered in a clear heat shrink-wrap bag for weather resistance. I have a Genasun GV-5-mod solar charge controller on order to interface for charging.
It should work well with my Icom IC-705 and (tr)uSDX radios.
