Do you have any m12 stuff? If I bought you a new m12 Powerextra battery would you wanna test it? Obviously you keep the battery...
I've got mostly M12 stuff and I've got a few off brand batteries too. I'd have to go home and see what brand they are I can't remember. I've been wanting to do a video doing exactly this with an off brand battery and a real M12 anyhow so maybe this'll just be a good motivation to do that.
its awesome!!
