Just beware of the heat that can buildup if the case is sealed!

You been watching Jehu's channel as well
Similar to the system I'm Building but mine is 4s40p.
Are they lipo or li ion?
Looking good so far
Thanks!
I just heard about Jehu a couple of days ago. I thought I was onto something special! Ha!
We did order a lot of the same parts, as it turns out. And, this being my first attempt at this, I was really relieved. I was sorta just winging it!
I don't understand why that guy bought a waterproof container and poked holes in it.
I'm looking to step up to 40p after I finish the prototyping on this. I think I'm going to toss this off a waterfall this weekend to see if it holds up! We can add the other 20 cells if it does

River said:It doesn't look like it's getting too hot--140f (60c) at the hottest parts. If it builds up heat too much, I was thinking about having part of the bottom cut out and replace with an aluminum plate, mounting the hot bits to it, acting as a heat sink.

That's LiFePO4 (Lithium Iron Phosphate), not LiPo (Lithium-Polymer)
LiFePO4 can be recognized by the 3.2 V nominal vs 3.6/3.7 for "regular" Li-Ion 18650's.
DarkRaven said:LiPos come almost exclusively in non-standard pouch formats and not in standard cylindrical cell formats.
DarkRaven said:18650 actually is LiIon exclusive. LiFe is LiIon as well. If someone builds a LiPo 18650 then this is still true, LiPo is LiIon is well.
And I don't know what your issues are, but I have no trouble telling LiPos apart from other types.
