Low Voltage Cut Off
Would it be possible to add a low voltage cut off? (or goto half throttle when too low) like you would normally find in a car ESC?
I am wanting to use a Hobbyking F-30A ESC in an airboat.
hi all the ESC's that i use in my planes have this option ,,much easier to set up them when i use a program card ,, Default factory settings: Brake: off Battery: LiPo Auto Detect Low Voltage: 3.2v (power down motor)
Spec. Max Motor Current: 45A Max BEC Current: 3A BEC Voltage: 5.5v LiPo: 2~6S NiMH:5~12cells Weight: 31grams
Programming Options. Battery Type Forward/Reverse Soft Start LV Setting (Ignore, Reduce Power, Stop Motor) Timing (Auto, Med, High) Switching (8,16kHz) Factory Restore
TURNIGY TRUST 45A SBEC Brushless Speed Controller $17.78
Turnigy Trust SBEC Programming Card $3.53 ,, but not to shore if the can get any water on this type ,, regards bart
Right, but this was originally intended for multirotors where there isn't much that can be done when the battery is detected as low. It would be better handled in the flight controller where landing could perhaps be attempted safely.
The code currently supports forward/reverse, timing, and PWM frequency adjustments, and there is stuff to report cell counts, but currently not anything while running. This requires some changes to do the checking while running.
Hi. Thanks for your Job! I used ESC from Ebay, 4$ type, red or yellow brick. I modified the firmware, that i have rc-car style. Problem 1) is, i have from forward brake, but from reverse i don't have brake. Problem 2): i burned all FET-s, with 2S pack, when i from full forward will brake. I give 6 piece IRFZ44N (50A, 55V), with max_brake_power: max_power/4, and also burned. Here is gate voltage for low FETs too low (5V), also i have ordered IRLB3034, 195A, 2mohm FET-s. What do you mean? I have 3200kV 540 motor, 10T, with 23T motor gear and 63T main gear. Problem 3) : with low speed motor is cogging.
