Yeah, I bought this Hyperion charger and it came with these boards. One is marked hyperion and has inputs for 2,3,4,5 and 5 cell
The fewest pins are 4 even on the two cell location.
Same with other board that says thunderpower, flight power on it. Still no 3 pin inputs.
My batteries I just purchased are the LiFe brand from Hobbico. They have a 3 pin balance plug thats slightly different than any of the options I have on these boards.
Guess I will try calling Hyperion service? Thanks
