Re: (5Th Run) E2e Bi-Pin socket
Got my Strion kit yesterday (5th Nov). Very fast delivery, only 7 days to the UK. I'm having a bit of a problem. I couldn't get the unit to work with the head screwed on. Loose, it lights up when the edge contacts the body so I know it works, but not with the E2e head on. After inspection I noticed that the outer collar of the socket, the widest bit, doesn't touch the top of the battery tube to make the circuit. I did get it working for a while by assembling the head first without the tailcap on and then putting that on last. I took it apart again to have a look and noticed the 17670 cell (a flat top Pila) has a dent in the top and the bottom is gouged by the tailcap spring. Now it won't work at all with the head on. Are Pila 17670s longer than AWs? I have a couple of protected AWs on order but they're not here yet so I've nothing to compare the Pilas with. I had previously been using the same bored out E2e with the same Pila and a KL4. I changed the width of the tube for the 17670 but didn't do anything to the depth as it all worked well. Should I change the depth of the tube? Any suggestions?
UPDATE 10th Nov
My new AW 17670s arrived from Lighthound today, so I set about measuring the cells. As I suspected, the Pilas are indeed too long. It was really obvious just putting them side by side with the AWs.
For anyone interested, the sizes are as follows:
Pila 600S (17670) - Height 68.15mm (2.683") Width at the middle - 16.80mm (0.661")
AW 17670 - Height 66.73mm (2.627") Width at the middle - 16.75mm (0.659")
[For safety I put a small piece of magic tape on the cell contacts before measuring with a digital vernier caliper, zeroing before each measurement.]
The extra length of the Pila pushes the socket forward enough to stop its outer collar from contacting the battery tube to complete the circuit. The AW does not. The pila works fine with my SF KL1 and KL4 heads but not the FM socket. So, the start of the thread where Fivemega mentions AW cells, that's actually quite important. The socket works perfectly with those cells. I'm a happy bunny!
