I have been using a Zippy 4000 mAh 11.4 3S 25C Compact battery for awhile now and wanted to share my results. I am getting 12.5 minutes with my IRIS running a Tarot gimbal and a GoPro camera. These batteries are cheap on Ebay when you can find them from Hobby King's store. They are 25 dollars and change and 6 dollars and change shipping. As they are compact they fit the IRIS great and are even a little smaller than the stock batteries. They come with bullet connectors but XT-60 are cheap and plentiful. The batteries comes with long leads that need to be shortened anyway. Just thought everyone should know.

NO WAY!!!
I am waiting on 3 of these to come in. https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct...
Hoping I get a similar result with the tarot and gopro on board.
Do you ever have issues with failing motors from heat? They get pretty hot after 3 stock batteries of flying, I hope they hold up.
Sounds good! After soldering XT-60 connectors to the battery, can they then be charged with the SkyRC e4 LiPo Balance Charger (standard charger supplied by 3DR)?
Yes.
This is good to hear Chris. I am not getting anywhere near that. I have 3 stock batteries, a 3850 Thunderpro and a Zippy 5000 and none of them can get near 10 minutes with gimbal go pro and legs. I think I know why but can't get any support on it from 3dr.
My RCOU Chan1 (which is the output of the Pixhawk to the channel 1 ESC) maxes out at full scale a few minutes into the flight causing the other channels to cut back in order to maintain attitude. The best I can get with anything is 7 to 8 minutes. I have have changed the motor, esc cal, auto tune, etc, etc,.
The only thing left is the ESC but I'm tired of working on it. I think I"m going to scrap it and build a TBS Discovery and put my pixhawk in it.
Would you mind posting one of your log files to this thread. I would like to see another log file from an Iris with gimbal and go pro compared to mine. I may find something that will keep me from starting over.
Thanx
Yeah.
Ive been using the zippy 5000 25C which also fits well and is good to fly.
I notice the 5800 30C should fit also which is what I may try next. But yea..I'm liking the zippy Lipos too.
What flight times do you get from the 5000 25C (I guess the 3S version)?
That sounds promising. Good to hear. The 6min you get from standard issue battery with Tarot Gimbal is a bit embarrassing. Will check them out.
