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
