Is there a way improve the LVC shutdown

Anything lower than a 4s LVC wouldn't work well since the diode voltage drop would be too great.

The nice thing about this "circuit" is that it can be contained on a small heatshrink-wrapped PCB with in/out wires (like a UBEC) and can even add a small PCB mount potentiometer to adjust the delay at which the LVC responds.

I'd try it but I don't have a test LVC to play with.

The only other way to make sure the voltage doesn't drop under quick heavy loads is to add a bunch of low-esr caps to help with the surges. It would be larger and more expensive, not to mention the initial hook-up spark due to the large capacitance you'd have to have.

I only skimmed over the technical jargen but I undestand what you are trying to do I can donate a LVC for you to try it out on. Suddenly I have one that is not being used at the moment,



Now I need to get a hold of Mike. Ten minutes before this happened I ordered the Gorilla Maxx tranny conversion and the other half of the FLM tranny case from him. I am hoping he will let me cancel that order so I can order a MGM controller and Neu motor. It doesn't look like he has many Nue's in stock though.
