Cheers steve i think i will definatly have a go at beefing up the O'rings and putting a step in the lens though.
Is LiPo such a good idea:thinking:
what happens when you get a leak and saltwater creates a full short circuit over your LiPo pack. I mean pressure build up in a closed enviroment is deluxe.
I would go for LiMa or nihm.

You make sure it's had sufficient testing like im doing now so that it doesn't leak! And when it does the water must have gotten in some how, so i figure the expanding gasses will then take the same route out. Plus the housing is strong enough to contain the pressure anyway.
I have build 3 dive lights from scratch now none of them have leaked (all have been tested to 10bar) my light have made >100 dives, but 1 thing is for sure one day they will leak. In my opinion all dive lights will one day leak comercially or diy.
It is possible that the expanding gasses put the O-ring back in place so that the gasses are trapped again
I did not do the math on this one but if I see the movies about LiPo on fires the pressure insdie a small canister must be enorm >10bar.

Sorry for my poor english
If you have already built 3 lights, lets be seeing them,time to show them off i think.
One solution would be to use an overpressure valve set at 0.5 bar. I think I've seen a light with this feature somewhere on a German web site.
I know this thing you can buy it here it is called Überdruckventil and costs €17,- I think that is a lot of money for something you should not need.

Thought i would send it offer for a test in a marine engineers pressure pot and the result:
It leaked!
They made lots of recommendations though.
