May be the setting of "Low Voltage Cut-Off Threshold" too high.
Default setting is 3.0v/cell. I am using 3.2v/cell
I had an experience that the shop help me to set at total 7.0v cut-off
Make sure the sensor cable is properly connected at both the ESC and motor. I have had some strange ESC/motor problems before, the problems were gone after I secured my sensor connectors at both ends (with tape).
Ching,
I had the similar experience. After i turned off all protections,it works well and i stop playing when the car slows down to avoid overly draining the lipo. This is just my case for your reference.
ching, if that is the case, there must be problem with the ESC programming function. Should I send ...
Ching, I bought 3 HW ESC and all have these problems so I am too lazy to send them back to repair. I just play with cautiousness by "manual cut-off". Now I set timer in the control to remind me to stop playing.
Hi Ching, i had the same problem on my 150A esc before, try set your esc voltage protaction to 3.2 or 3.4V per cell but i suggest you to set your radio control count down timming to 11mins - maximum 13 mins (Use your phone if your radio system didn't came with this function)... your batteries voltage should be 7.4 to 7.6V after the run. 3.2 or 3.4V is too low for the batteries.
You can also download their ESC setup software from their site or borrow it from your friend for easy set up your esc.
