I'm trying to source some battery contact connectors for sliding straight metal strips into. They're the sort of thing that are used in power tool batteries, but I want to use them for a different project.

Example Photo 2

Can anyone tell me what these are called and any example part numbers / links? I've tried searching for things like "battery contact", "power tool battery contact" and a few similar terms, but have drawn a blank so far.

For reference, the ones in the photo came from a Makita Battery Case Kit that you can buy to make DIY power tool batteries.

  • "What are these connectors?" is allowed, but "Where can I get them?" isn't. – user253751 Apr 22 '22 at 11:08
  • @user253751 - okay: I've edited the question accordingly – DrAl Apr 22 '22 at 11:13

    Every OEM wants to protect it's proprietary charger interface with some custom parts and physical uniqueness. What makes you think otherwise? – Tony Stewart EE75 Apr 22 '22 at 12:56
  • You might find bus bar connectors or some kinds of fuse clips as substitutes. – DKNguyen Apr 22 '22 at 15:09

    @TonyStewartEE75 The ones I photographed were off a copy of the Makita battery from a Chinese supplier. I've found several suppliers of these "Battery Kits", all of which include the same connector. Given they seem to have slightly different versions of the battery connector PCB, I assume they're from different manufacturers (and probably not Makita). Therefore I assume that the connectors can be bought. I don't know for certain though. – DrAl Apr 22 '22 at 15:37
  • I can buy clone connectors too but $300 MOQ. Try AUK if you have some volume – Tony Stewart EE75 Apr 22 '22 at 17:51

They are "spring leaf socket PCB terminals". The ones in your pictures are custom made. You can buy similar ones off-the-shelf:
