Wattage IC-15A premature BEC cutoff
I've been pleased with Wattage ESCs for some time but the IC-15A is driving me nuts. It's controlling a Wattage 370 motor from a Wattage six cell 800mAh NiMH pack. The pack charges up nicely to around 8.4 volts but the BEC Cutoff kicks in at full throttle after about thirty seconds of running. I can cruise around at half throttle for another six minutes or so and then the BEC kicks in again. The pack voltage at that point is around 7.4 volts. That would make sense only if I was running an eight cell pack. Is there a way to set the number of cells/voltage the ESC is looking for or is the ESC not functioning properly? Could I have a bum motor that's drawing an excessive amount of current for some reason? Any suggestions would be most helpful. Thank you for your time. --Jim

RE: Wattage IC-15A premature BEC cutoff
ESCs, especially simple brushed ESCs tend to either work, or smoke. It's far far far more likely that you either have a bum battery or a bum motor. The battery may be capitulating under the "stress" imposed by the motor.
BTW, what are you trying to spin with that motor? Trying to spin too much prop is another likely culprit.
