| I believe suicideniel is correct about the "clamp" function. I just soldered mine to the back side of the power board where the battery leads poke out. |

I believe they are refered to as 'voltage clamps', and the purpose is to absorb transient voltage spikes that might harm the cap or batteries... something like that I think i read a while back...
They are surface mounted normally, so good soldering skills and a good iron are required. |
- Just to add for the comments above
Zeners/Transorbs voltage was selected to protect FET's from voltage spikes, running at 4-5S close to FET's rated voltage and for caps. With temp going up caps rated voltage goes down as well over the time, so to keep them happy I installed zener.
And as bonus reverse polarity protection for FET's, not for wires and bad soldering :)
DO NOT CHECK it!
