An idea for future CC ESCs

Not sure how it would work out on a car. On there website they state that they have one in the works for cars, but I could have sworn they said that over a year ago.

I received a CAR version of this for beta testing. Tested it, sent them my results and my thoughts, and never received a reply back... So it doesn't seem they are interested in producing a version with pistol-radio software.

How did it perform?

Strap on Temp sensors can be unreliable and give varied results. I've seen differences on Nitro motor temp sensors of up to 25 deg between lasso and temp gun readings.

Perhaps something else to consider would be a little audible warning on ESC temp and Lipo volts. i've seen the external audible warnings on pack voltage but surely that's easy to employ within an ESC of the MMM size.

It worked like expected, but what I didn't like was that after it shut off the throttle, and I returned the trigger to neutral, I could still grab full throttle and draw the batteries down further. In that situation the Cellshield just didn't respond fast enough. Of course I wouldn't normally treat Lipo batteries that way, but it was necessary for testing purposes.

Yea, thats not completely uncommon though with external LVCs. Wish I coulda got one of the beta units. They were supposed to e-mail me when they were ready and send me one as well for testing, but never did.

That means DE broke off all contact with the people who could help them get this product to the market... Strange move if you ask me.

Another idea I was thinking about, which also relates with the balance plugs, is if you can plug them into the esc so it can detect just how many cells you are running.
Just a thought.

Not if they're done properly. A lot of lasso-style sensors don't give an accurate reading because they often don't have good contact with the heat source. If Castle made an official motor sensor that used an aluminium clip-on clamp that wrapped most of the way around the can with the thermistor thermal-epoxied to it, then heat transfer would be very efficient and reliable.

I just think it'd be a simple, elegant feature that could be an invaluable failsafe measure IMO.

Castle speedos already do, with Auto-LiPo.

Auto lipo though is a guess I've still messed it up before plugging in a disharged pack and it just thought it was 4s pack instead of 5s...

Same has happened to me as Arct1k, after my MMM reset on its own. Luckily I noticed the power drop to save my lipo's.

[Dagger Thrasher]

Okay, fair point. I'd forgotten about that scenario.
