Ni-ion 4 cell won't light up KK2.1 board...

[ivorn]

Hi to all.
I have put together a 4 cell Ni-ion 3.7 trustfire batterie pack for my tricopter as per the Geek Guy. Showing all cells good etc. But when I connect to my tri I get no power. I get a correct 4 cell read out via my Turnigy Qanum Telem but that's it. Do I need to change my power output settings on board? Currently running 3 cell 2200 bat at 9.9 cut off.
Any bright spark ideas?

Your batteries power your ESC/BEC. Your ESC/BEC powers your board. What output does your ESC/BEC have ?

The board might be dead if you sent more than 6v into it since they are supposed to be powered from a BEC or powered from an ESC, both of which only output 5-6v...

It's setup as per David Windelstal's tricopter, can't remember, but the board is fine was flying ok after I tried the 4 cell.
