I'm looking at getting some 2 x 18650 battery cases made and need advice on what material to use.
The idea is:
1. Take 2 tabbed 18650s and solder them together with a cable.
2. Put battery into plastic case (on right of picture)
3. Fill the cap (on left) with appropriate glue or silicone.
4. Shove the cap and battery together, forcing glue into every gap and squeezing out all the excess.
5. Tighten down cable gland.
Obviously this is a permanent seal and charging is done through the cable.
The wall thickness is 2mm in the middle but 4mm at the ends.
My aim was to make a sturdy, impact resistant case for 18650 cells, but then I decided that I might as well make it waterproof too.
My machinist has given me a list of plastics that he prefers to work with:
ABS
HIPS
PA6
PP
PBT
PVC
Any advice from the dive pros?
If you had the choice, what would you use?
