Hey there fellas! Oh wait, that's Garage 54 videos intro :)
While I read more about high voltage batteries but I don't commit to one yet, I'm playing with some cheaper alternatives.
This time, I'm planning to use five 20V batteries from Parkside/Lidl, which are easy to get (if you're lucky with their timing), relatively cheap, can be used with a number of tools and easily charged/replaced.
To hook those batteries, I've designed and 3D printed an adapter, which is made of two parts: the base and a top cover, which allows the copper contacts to be run in the middle. Here's the planned assembly:
And here's a test of a single base:
I can tell that the dimensions are pretty much bang on. The battery slides perfectly and is kept in place thanks to its spring.
From what I read online, these batteries are capable of 20A discharge or even more. That's 2kW at 100V, which is almost 10x what I get from the 300W bench DC supply. That should be enough for some indoor manoeuvres with the Samurai in the garage :)
