Default RE: LIPOLI SET UP FOR SPEED 500

afischer,

Just a followup note: I assume that the speed control you bought is compatible with the Li-Po battery you bought at the same time ... the supplier should have made sure of that. Reason being, the battery eliminator circuit (BEC) in the speed control needs to shut off power to the motor before the voltage drops below the critical level to prevent battery damage. For a Ni-Cd or Ni-MH battery, that's around 1.1 volts per cell, or 7.7 volts for a 7-cell pack. If you're using a 3-cell Li-Po pack, the critical level is more like 9 or 10 volts. If it goes down to 7.7 volts, your Li-Po will be damaged. So if you have any doubt about where the voltage cutoff is set, read the manual and reprogram your speed control if necessary.
