Ask HN: Resources for hacking battery-powered tools?

[HRJ7]

I have a growing collection of battery-powered hand and lawn tools, incl. larger machines like lawn mowers and snow blowers.

Are there any online resources for learning how to repurpose these kinds of batteries and motors to, e.g. convert an ICE powered machine to electric?

Okay, I have to ask. What is ICE power? I tried the Google and as you can imagine the results were not helpful.
