GTHound - the rate of change, but as read from a MAP sensor is what I'm thinking about. That would make a "universal" controller truly universal. If someone wants to add an RPM switch, then that should work too. WB Projects - I do think in a lot of applications like yours, you're right - you...

I'm finding C ratings to be kind of nonsense - there's actually no standard for measuring C rating in terms of voltage drop. I've thought about establishing some sort of standard for that in a video, but I can't do the video down here in Texas (my load tester is still up north). Lipos may...

I'm very glad to hear it. Going to 12s2p should, in theory, cut your voltage drop in half. 12s3p should cut the voltage drop by 2/3rds. Of course, I'm not taking into account any losses in the connectors and cables - have you measured the voltage drop across the cables while running? You can...

That would be an interesting project to see.

I'm also wondering if there's a way to control is purely with a map sensor - in other words, if there's a sudden drop in MAP, it turns on (maybe scaled on the degree of drop), but if there's a sudden spike up it stays on unless it goes too high, then it could shut off... Just thinking out loud...

Hi all. Now that I'm pretty comfortable with finding a "sweet spot" setup for the mechanical and drive aspects of these things, I'm starting to think about better control methods. I can think of several: 1. Do what I'm doing now - have it turn on to max power above a certain rpm and certain...

Not yet. I've had a few issues with an arduino in general. I think it was mostly EMF issues (which could be solved), but it could have been code. Now that we have a basic formula down for the mechanical and drive aspects of the these things, I'm starting to think about various control...

Nice!

Good to know.

Best of luck WB! I'm sure it'll work out.

Welcome! Your requirements seem ideal for and electric supercharger!

I'm in Texas right now, so I don't have to exact size(s) available, but there's a size of pvs electrical conduit that those cells fit in perfectly, and there's a tap size that happens to fit into that conduit perfectly - which I bought (because of course I did). That makes making very high...

Welcome! I actually have 180 of those cells. The biggest issue is the current capacity of the strips. I have yet to figure out how to do it where they can legitimately handle the kind of current we need. I have an idea (and bought some parts), but am still doubtful. I do intend to do some...

I was able to interview David about his project - check it out:

I hear you!

What's really unfortunate is that the Hobbywing ESC would be great for your setup. As much as I love the MGM stuff, it's expensive and getting things serviced is difficult. Don't get me wrong - great guys and a good product, but with the Hobbywing being 450 USD, it's tough to say no to it.

We're here to help. I'm a little touch and go right now building this new house here in Texas, but I'm turning my attentions back to the forum and all. Welcome!

That is really great stuff. WB - this is the guy I was referring to in the other thread...

Sorry for the delayed response - had an eventful two weeks driving down to Texas and dealing with things. Three flat tires and I now apparently own a dog. But to answer your question, from Battery Hookup.

I'm sorry to hear that. Another guy I'm talking with has had very good results with Castle and Hobbywing. Though I feel your financial pain...
