Heat transfer in divelight head

[patrickDM]

Hi,

Just wanted to post some quick pictures on the final setup ...
I've used one of Alunatec's POM canisters (fits 2 * 4 * 18650 pack, i.e. 4S2P) and made a small
circular PCB to fix 2 RC-type connectors & taskled's HallSw.

The HallSw is triggered by the magnetic switch (also Alunatec) ... so far, all seems to work fine (have
yet to take it underwater), although I'm a bit concerned that the POM canister doesn't have an
overpressure-device ... technical RB diving is sufficiently trilling, no need to add a potential pipe-bomb
to my thoughts

Any idea's, experiences ?

Cheers Patrick
