I was wondering how well those heatsinks performed. I had been eying those on ebay too. Nice photography as well. Where'd you get the lock/key set for the circuit? That's a real nice addition. Finally, you can buy 18650 battery holders which might be more convenient.
Thank you
The heatsink is great for its size, it works OK imo, but this is my first build so you may prefer to ask someone with a little more experience.
I got the key lock from a local electronics store, it costs like 3usd, PM me if you want one.
The battery holder would've been ideal lol... lucky me i had tabbed 18650 so it's not that bad
