Hi...I posted a question on the YouTube video with the same title. It was suggested I come in here to re-post the question.
A little background prior to pasting my original question: I picked up a used hex with brushless gimbal on rcgroups. It came as an entire package....batteries, transmitter, extra props, camera, etc. Up to this point, I have only been dealing with quads using 3 cell batteries. This hex came with 4 used batteries at 4 cells each. 2 batteries are 30-40C Turnigy 4000mah and 2 are 40-50C Turningy 5000mah Right now I can't figure out why the batteries are
a) getting much warmer than my 3 cells ever did
b) only getting a measly 4 or 6 minutes of flight time depending on which battery
c) puffing up by the end of flight
So as I was questioning this setup by the previous owner. I went to YT and found the video explaining batties esc's motors. Here's my question:
Ok...I went over to your forum and I did not see any multirotor threads. But maybe you can help.
2214 Century 700KV motors x6
30 Amp esc's x6
Current battery 14.8V 5000mah 30C
12x4 wooden props
3500 grams fully loaded with gimbal, camera, and battery
I bought this hex used. It has a brushless gimbal and a heavy lift kit. I'm questioning the battery selection (and esc's for that matter) by the previous owner. I only have that info on the motors and can't seem to find any data on them. The closest thing I can find are SunnySky's 2214-11 700KV. Even that spec sheet is iffy but they are talking 440 watts per motor.
The batteries that came with this hex are questionable in age and condition. But I'm only getting 6 minute flights and very warm puffed up batteries at the end of a flight.
I was looking at ordering a 14.8V 8000mah 35C battery and plugged in the numbers based on the calculations you gave in your video. I saw a much higher amp result and figured I'd be good to go with a "bigger" battery. But judging by the response you gave, I need to be looking for more C's. Now I'm confused. It seems to me that just based on the equation alone, raising either number (mah or C) will provide more amps.
I know multirotors tend to get away with lower discharge rates. At least I've read that in the past. So based on your response, I'm not sure what to do at this point. any ideas?
If I left out any specs, please let me know. Thanks.
