I "inherited" a Conentool 24 V cordless lawn trimmer with plenty of accessories, but no batteries or charger (which are pretty important [citation needed]).

Instead of throwing it out, I thought it must be possible to convert it to my other available batteries!

Testing

Battery Mount

Originally I toyed with the idea of making a dual-sided adapter that would fit into the original battery holder of the tool, but there were a bunch of reasons against that:

  • difficulty - I had no Conentool battery available to take measurements, so it would have been a reverse-engineering task
  • time & effort - I had no interest in putting any more resources than necessary into the crappy tool
  • necessity - I have no other Conentool equipment, nor do I plan to ever buy it

So obviously, a permanent conversion would do.

I got an original Makita adapter plate (thanks Patrick) and 3D printed the surrounding battery holder in PLA.

Assembly

...if you want to call it that ;-)


more details coming soon
