Thx chaps, glad you liked it.

I should mention after just checking the voltages at the connection, I do seem to be getting some odd readings that I haven't quite sussed out yet.
The readings are:
3v is giving 4.7
4.5v is giving 6.7
6v is giving 8.7
7.5 is giving 10.7
9v is giving 12.9
I compared this to my 3.7v ego batt and was getting 3.4v which I seem to recall is quite common but does seem to imply the readings I am getting are correct.
That said 8.7v (6v)sounds very high but to be honest the experience seems fine and certainly not overly hot, and for the record nor does 10.7v (7.5v).
Weird huh.
ATM I'm not sure if this is normal or maybe my pack is just a bit rubbish. Anyone with a bit of electrical knowledge feel free to chip in.
