/diy/ - Do It Yourself

I've built my own, empty casing and circuit board cost about $12, and you pick whatever cell you want. I used chink 2.6Ah cells at ~$2.20 from a relatively reputable seller, they do alright, but under heavy load there's a noticeable difference between them and the genuine Makita battery (ie. pressing down on angle grinder). Still, under normal use I don't feel like they perform much worse. In drills, drivers, any lower-power devices you don't notice a difference at all.

After getting burned again, then resoldering half the tabs, the 18V 7.8Ah Makita pack is finished.
Except that the fucking chinks sent security torx screws so I'll need to get some philips ones before I can put the top on.
