That’s a weird connector on the discharge cable. Never seen that.
How did you hook it up to the XT-60 connector of IRIS? Did you solder on another connector or are you using an adapter cable? If so, how are you fitting all the cable stuff into the battery door?
I de-soldered the original and put EC3 connectors since that’s what I run on everything (changed the Iris plug to). You can put xt60 on it and it will fit. Did it on a buddies. It has super short leads so you better be good at soldering and shoving a toothpick under the heat shrink will let you slide it up after you’re done.
I wont tell no one about your speed secret’s. Their safe with me!!! 
Yes that cable for the led is sure tight. Ya think they could of put it in a better place.
Last weekend I did some test flights with all my batteries to confirm or dispute my theory that the 3DR branded batteries are performing extremely poorly.
Here is the test sequence:
- Balance charged all batteries to max
- IRIS was equipped with GoPro 3 in waterproof housing (No Gimbal!)
- Environment basically wind free, with wind below 3 km/h
- Took off in Stabilize mode and placed IRIS at 9.5 m, switching to ALT_HOLD mode
- Maintained position manually, “sticking” to one position
- Waited for Battery Failsafe to kick in and land the Quad automatically
I then went through the log files afterwards and assembled the following information for each pack
Battery___Flight Time___FS Volt__A Used__A Sticker__% at FS
3DR-01___618__________10.33____2400____3500______0.69
3DR-02___583__________10.39____2265____3500______0.65
T36-01___611__________10.36____2583____3600______0.72
T36-02___716__________10.40____2986____3600______0.83
T36-03___711__________10.38____2979____3600______0.83
T36-04___690__________10.41____2894____3600______0.80
T45-01___859__________10.42____3397____4500______0.75
Here’s what each column means:
Battery: Pack. 3DR are the 3DR branded ones. T36 is a Turingy 3600 mAh and T45 is a Turingy 4500 mAh one.
Flight Time: Flight time in seconds from liftoff until Failsafe kicked in.
FS Volt: Voltage at the moment Failsafe kicked in. The closer to 10.5V, the better
A Used: Ampere used when Failsafe kicked in.
A Sticker: The battery rating from the sticker.
% at FS: Percentage of capacity (A) used when Failsafe kicked in.
A few comments:
- The T45 battery is new and I only used it twice. I expect it to get a bit better over time.
- All other batteries were flown for about 8-10 cycles.
- The T36-01 battery seems to perform worse than the other T36 batteries and I would consider it defective of at least suspicious. I will need to do some more tests with that one.
Looking at the 3DR batteries they perform really poorly compared to the Turningy ones. Using the basic law of proportion and assuming that the battery should be at Failsafe voltage when at about 80% of the capacity is used (That’s what the Turningy 3600 mAh do), this would mean that the 3DR batteries do not really have a capacity of 3500 mAh, but only about 3000 mAh. That’s certainly not what I paid for and expected.
