apply a higher voltage to the cooling fans
Hello,
need some help with the following,
I own a large electric RC helicopter. the motor is getting very hot after few minutes of flying. I would like to add a fan to cool it down a bit (not uncommon in RC helis).
the voltage of the Lithium Polymer battery I am using is around 32V (8 cells in series). I'll be using small computer type fans which are available at 5V and 12V.
can I connect two 12V fans in series (24V) with the higher voltage of the battery pack (over 30 volts) ? or is it going to toast the fans ? the fans will be operated for flights of 10 minutes max.
I would to keep it as simple as possible without adding resistors and such...
thanks.
