Anyone know if this esc will survive a 4s LiFe battery? The initial voltage might be a little high, but once it pulls down a bit, it should be fine. Has anyone tried this yet?

Don't recommend it, I tried once and I fried it in 10 seconds at 3/4 throttle
 sorenlaf 124 points
Thanks for the information. Do you have any idea what was the current at 3/4 throttle?
 sidd232 1066 points
It will depend on the motor/propeller combo, mines with 3s got around 18 amps at 3/4 throttle. The esc will fry not because the motor might draw lots of current but because the capacitors and resistors are not rated to 4 cells

I understand how motor setup works. I was asking about the current with the setup that you used when you burned out the esc. Sounds like you were exceeding the rated current. Also, please confirm that you noticed I was asking about a 4s LiFe, not a 4s LiPo. I ask because you're now just saying "4s." Also an fyi. The resistor are most certainly rated for 4s (or 40s, and probably 400s). The caps may not be, but a fully charged 3s lipo is 12.6v vs. 14.4v no-load for a 4s LiFe, which drops to about 13.2 as soon as you draw some current. It's normal to spec caps 30%-50% over the working voltage, so the 15% voltage difference in the battery seem unlikely to be the problem.

Are the ESCs reverseble? I want to use them for a Submarine...

No, they are not.
 sidd232 1066 points
What do you mean reversible?, if you mean that you need your motor to spin the opposite direction sure you can go it by swapping two of the three wires to the motor.

i know this is probably meant to be used in a helicopter but could it be used in an rc car? or if theres a better option id appreciate any advice
 sidd232 1066 points
This esc is not intended for helicopter as a primary, you surely can use it in a car.

On two occasions after I used this ESC for a little while, it seems to go into a weird state where if I turn up the throttle at all the prop just stutters around very slowly. I tried connecting a fresh battery, but the same thing happened. After waiting a while it goes back to normal operation. I thought it happened because I got some snow/water in the motor the first time, but the second time it happened the plane remained pretty dry. What does this mean?

This means your ESC and calibration has gone out of sync. This means you need to reprogram it or reset it to default. This is quite common with these however luckily this only happens on initializing.

It also might be a bad connection on one of the three motor connections. I've seen similar behavior when one motor leg has been disconnected.

Dont know if these have reverse volt protection but I may have reversed the polarity and killed it as it smoked a bit and something glowed under the heat shrink when I applied power.

When I took the heat shrink off and had a look, four of the terminals on one of the chips were soldered together and some of the chips are well cooked. So I dont know if I killed it or it was a gonna from the factory. Still at this price not a great loss.

Nice and cheap ESC. Very basic, suffers from the low pass filter on the PPM input. If you want to use it to fly a multocopter, I recommend you modify it for higher PPM update rate. I made a guide here : www.link t t p s : / / www.link

I have 4 of these on a quadcopter, with Hextronik DT750 motors, HK V2 flight control board and a 3S 2200 40C battery. They work great. Very easy to stick program. Will buy these again.
