Well I would section off the battery compartment since I think foam all around the chip is not that good. but I guess that is a pretty good idea. but how hard does it hold heat. if this thing causes the battery to get super hot we aren't off any better since your mod's lid will still blow off from the pressure of the flame thrower of doom.
Its sooooo good to see you back in these halls!
We can actually do that now with his desktop bench rig. All we need is his IP address!(and google earth to track the mushroom cloud)haha then you'd have to worry if you ...... someone off on the forum hacking your settings.....oh my firewall and antiviri for ecigs

Crap! I was actually planning to use that thin anti flame sheet that plumbers use when soldering copper up by the joists to prevent the house burning down, as a battery wrap around 5 sides of the LiPo & perfing bottom plate but now you got me thinking it might be a bad idea. Perhaps aluminum heat sink battery case on 5 sides wrapped with the plumbers sheet? -- I'd lose my expansion tolerance. Have to fall back on insulating the board, my face, and hand, then trusty reflexes to save the rest of me. Fortunately I chose an Aluminum case.

To be honest, the outer casing of the mod will protect you long enough should something go south. But assuming you have everything installed correctly and it's working fine, you won't be putting the much stress on the lipo....not near what an r/c user would.

But if you can't dissipate the heat generated, it is a bad thing. I'm gonna add an aluminum wall insulated on board side between board and battery extending on an L shape to cover battery compartment top. That gives me a heat sink on 4 sides with and open vent on 5th & allows pre planned insulation for face & hand.

A couple of thin cuts of adhesive backed weather strip from a hardware store applied in several places on the LiPo would provide isolation and anti-rattle without affecting heat dissipation from the battery. It would still allow expansion and contraction of the cells and it would be very cheap.
Do you mean insulated weatherstripping tape or the aluminum foil tape they use in HVAC applications as the latter makes more sense to me personally on a thermal basis after a DarklySpectur embarked a thought that ruined my visions of a well laid plan. That HVAC Tape might be an excellent addition to a layered precautionary defense especially for the 3d printing plans others will employ. Thank you for the thought! I like it!
No one believes we will ever hit the point where one of these Will light off on us but our designs should incorporate a plan to handle the eventuality of a possible failure.
In the Beta Mods Evolve machined the base joint to vent and break away in event of a failure.
Common sense.

Try this on for size:
Double sided thermal CPU/Heatsink tape.
If you don't like the size they make it in any size you want just about.

There is an excellent solution & thought, but at an estimated cost of $30 to cover a $12 LiPo I'm personally gonna lean toward the foil stuff that is about $7 a roll.

When I look it says US $6.99 what are you looking at that cost $30 dollars
PS - for $6.99 you get enough to do 30 batteries. Beside shop a little there are a Gazillion people selling the stuff in different sizes and shapes. Gee!!! There is one guy selling it for $2 buck.
At a certain c rating it wont matter what you try to insulate with, it will cut thru even the lipo bag etc. like it wasn't even there.
Buy a well research cell and your good to go.. Just know ~10 amps can cut thru a 1/4" of steel or take a huge chunk out of a screwdriver lol.. Be careful building is most certainty..
Some 3s lipos are 200amp rated

There not looking to insulate anything they just want to hold the battery in place and not interfere with the heat radiation from the battery to prevent the battery from over heating.
I wasn't thinking of anything expensive or fancy, just something to provide electrical isolation from the case, shock absorption, positive placement that doesn't allow the battery to rattle, allows expansion and contraction room without a lot of pressure, and allow no restriction to cooling. Something cheap like this:
Shop Frost King 0.375-in x 17-ft Gray Foam Door Weatherstrip at Lowes.com
Just 2 pieces front and back lengthwise to the battery and maybe 1 on each side. In essence easily suspend the battery in the battery cavity area. Not a big deal, but would probably easily do the job. And did I mention cheap? I like cheap.
