Found a 12v cordless drill, battery is dead (according to the

Heh. I was looking at doing this just the other day. The amperage is about half what you'd ideally want, which means you could burn up the power supply if you work the drill too hard so keep that in mind when you're using it. Lookup "cordless drill to corded" on youtube. There were a few vids that show how to do what you're wanting to do.

It might work but shitty, motors need lots of current at startup and under load. And that looks like a nice makita so dont accidentally destroy it.

Makitas are nice but those batteries weren't the best. I have 2 identical sets with 2 batteries per set and all the batteries are dead. I'll have to see about rebuilding the batteries with lion and changing the charger innards.

I wired it up and its working. How much current should it get when under full load?

probably like 15 20 amps with something older like that

OK so an old computer power supply unit might get the job done

I would look into just rebuilding the battery pack instead of rigging it up to a psu
Its not that hard

Is it wise to buy this from China?

>>1051604

Yes but try to figure out the actual capacity before purchasing. Chinks always lie about it.

>>1051612
How do I measure it before purchasing?

>>1051625
with really long cables and a multimeter
