Aluminium canister

[marc.collin]

hi

i would like to know for those who have created a canister in aluminum what strategy have you used for the bottom?

have you put some glue, weldering, tool a full cylinder and remove interior..

I used a stock piece of aluminum 76mm with 6.3 wall, machined the ends square and on the base I machined up a piece of delrin and glued it with JB weld. A one piece canister is a big job to bore out, solid rod in the sizes required are expensive and waste a lot of material, a two piece design saves a lot of cash.

Below is a cross section of the machined parts for the canister it seems to work well.

I have once used old pneumatic cylinders for canister and also for light head . Very DIY friendly , special for battery pack in ''rod '' - 3S . Instead of cap with piston rod I use another blind bottom.

I have used cylinders similar those 2 but less massive with ID 40mm with battery pack 3S ; 5000mAh

I think UTD use AL for their pro level battery canister. The canister is in box shape tho, not cylinder shake

have you used theses canister in cold environment?

aluminium conduct humidity... so surely can get some trouble

if you start to have humidy in your battery pack... don't think it's a good mix.

delrin don't realy absorb moisture
