The octo i have that the AQ autopilot will go on has motors designed to 6s lipo batteries. After testing the motors with different batteries and props I find that 6s a123 batteries with 12" props instead of 10" props give me the thrust I need for a successful octocopter.
The question is, do you think or know if it is safe to use the 6s A123 battery instead of 5s lipo?
The voltage for a 6s A123 is 19.8 and a 5s lipo is 18.5volts.
6 years ago I found out the hard way that too high a voltage can cause major damage. I used 5s A123 with a MK FC many times with no problem but when I connected a brand new A123 pack with a fresh charge I fried the board.
The maximum voltage on A123s is 3.6V for 21.6v. Lipos maximum voltage is 4.2V x 5 for 21volts.
So maximum voltage is only .6 Volts higher.
