I've found lots of useful info here(too much!), but nothing that directly answers what I'm looking for. Possibly I should be on a RC or battle-bot forum? But I would like to avoid advice from the inexperienced and I've seen some pretty in-depth knowledge of what's possible here
I've been thinking about building various battery-powered tools. Some that need to be in a much higher power class than what this post is about. I have a few conditions to work with. 1st that I have the Hart 40-volt batteries which are not being used often enough & a pair of 3D-printed holders for those with 12 gauge pigtails(maybe a bit light?). 2nd, I want something in a power range of 1/2~3/4 horsepower. Additionally, I would like something that is capable of controlling the battery amp draw - I'm new at this so I'm assuming there should be many different ways to do that. I also want a controller that can control how quickly it ramps-up/ramps-down on motor speeds & be reversing
I don't want to spend too much, but I also don't want to choose a budget limit just yet. Lets just say I want a best 'bang for the buck' entry-level choice for what will work, and something that wont burn out or break if a mistake is made
I don't want to describe the more interesting project ideas, as they might be worth developing later into a business. But, one example of the sort of thing I would like to do is a Dremel type tool, with a tethered battery on a short cable. Something that's intended to be carried on a shoulder sling, in a large pocket or set on a workbench. Keep the tool head as compact & lightweight as possible by having the motor controller located at the battery. The tool would have a trigger control, so possibly the cable will have three main power leads, and three light gauge wires to connect power,ground & signal. The trigger could be a potentiometer. So this sounds like a bike controller? But scaled-down. Maybe something for a powered skateboard?
