Need an alternative powersupply for quadcopter..!!

Posted by SANJU.R.S on May 20, 2011 at 2:28am

I need a power supply for my quadcopter because the lipo I used in the copter get damaged yesterday. Now I'm unable to purchase a new lipo. Next week I'll have an indoor demonstration of this quadcopter. Wired power supply is enough for this. So I urgently need a power supply w/ extension cord.

I have a 12V power supply but it is only rated for up to 3A. Based on the specs of the motors (http://www.hobbyking.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=4854), each motor can draw up to 18Amps at 11V .

Does anyone have any ideas to build an alternative power supply? I've looked into ATX computer power supplies 12V output but the motors specifically say 10V max.

    Car battery would work just fine as long as it's 12V. If the ESC's can take 12 to 14 V. The motors should be fine as long as you don't give too much throttle. Are you running a 2 cell lipo now? If it hovers on this the motors should not see the full battery voltage unless you are at 100% throttle. You will just be operating at a much lower throttle setting to hover.
