the bigger the mass (volume), the more heat it can absorb before saturating. the more surface area exposed to air the better performance of said heatsink. there is a balance u need to consider, not just slap the biggest chunk of metal on it and call it a day.
if the air exposed area is same for both heatsinks and they are made of same material, then the one with more volume should have better performance.
but there is also thermal conduction that u need to consider, as different material transfer heat differently, for example:
Hi, after breaking my foot due to an esc error and over discharging my practically brand new battery pack which I poured my heart into building, I took a few years brake from eskating. Not a concious decision. Kinda just lost interest a little bit.
Anyway… Very cool to see you guys made a new independent forum and to still see some familiar faces.
Now to my question: is there a place where I can efficiently read up on what I have missed regarding technical development? What are the standard parts that everyone uses nowadays? Any new best practices? I know back then, focboxes and Samsung 30q cells were all the rage. Did this change?
I see unity is back from the dead. Does Jason still produce them? Are they any good? Ackmaniac still around?
So I would be glad if anyone can for example recommend 2-3 good build threads that you consider pretty much standard so I can get up to speed
Molicels (P26A, P28A, and P42A) are pretty much the gold standard for moderate to high power packs now. The really high p-count packs or lower power ones can use the 5000mAh 21700’s that have been appearing over the past year or two.
30Q’s don’t have a very good rep anymore as there have been complaints of them forcing pack voltage imbalancing that’s a lot worse than other cells. Nothing definitive yet but enough people have been complaining about it that it seems something is up.
My question is, what went wrong? Is it that the fuse holder is rated at 32V? Should I just throw it away and just solder a fuse there? Should I just go back to fuse-less (it was working fine for 3 months now)
Hahaha thank you VERY much for the entertaining summary <3
Don’t know how I feel about the high voltage… 12s felt like plenty back in the day
Glad I missed the drama.
Is there any news on a good panel mounted plug for connecting sensor wires to the enclosure?
(Doesn’t come loose, break, waterproof?)
I know that is one thing that I really used to search forever.
Even different aluminium alloy would yield different result on thermal transfer.
But to be real here, I think any heatsink would work relatively well in our use case, the chance of anyone ( regular people, not racing board, most of them don’t use vesc anyway) can heat up enough to saturate the heatsink is very silm. And if u really saturated a heatsink, u kinda doing it wrong
