Can anyone please tell me 1:if I may need to post this elsewhere as I'm new here and 2: what's the biggest battery I can possibly fit in the phantom battery compartment?

I just filed a couple cutouts on the body and door so I can connect from the outside.
ElGuano said:JTheed, nice to see another dual mad dog user. What voltages do you run down to? Conservatively I can get 18+ min on 5400mah, pushing it I can get 21+.
ElGuano said:Jtheed-the 5400 is two maddogs combined into one battery.
Djidan, those are great results, what are your voltages set to for alarm and auto-land?

They have not been adjusted, therefore they will be what ever the defaults are. I think I could possibly lower these to give me even more flight time, but don't want to damage my batteries.
havasuphoto said:Very good points. I've noticed when I pull out my single maddog 2700 mah, that the exit voltage is about .10th lower than a standard battery. Normally, a DJI 2200mah will come out at 11.25 or so...while the MD will come out at 11.15.
I never wait for the 2nd level, always landing at 1st level. My Phantom is a pig-and trying to land it with 2nd level warning, on my "heli-tub" is just too difficult.
When I see 10.9 volts-loaded, on my iOSD-it's time to take the Goggles off, and the Phantom is always right in front of me. I use a time on my remote to remind me.
Also-I write in a log every flight-all my batteries are numbered(I think I have 14 or 15 now-including 5 maddogs). I write down the voltage in/out, and after 5 minutes(or when I finish the next flight), I record the voltage of the battery...I'd like to see at least .10 volts returning.
Also, I monitor the difference between the 3 cells. I think someone mentioned no more than .70 of a volt between the 3? Anymore than that, and it might be time for a replacement?

Wondering if you had some side pictures of where you did your cut-outs? Also, couldn't you just file open some spots on each side of the battery door itself?
