Damon is definitely on track. He is very knowledgeable in the battery mod world. I personally use dual 1850's but 2200's will work as well. Weight is a big issue you want to stay away from. Battery mods actually be detrimental and not helpful if done incorrectly or the wrong combos are used. Feel free to reach out to me personally if I can help with any info. My name is Ralph and I'm the owner of FlyHighUSA. 270-473-1409Hi guys, i have been reading this thread with great interest, at one moment Damoncopter suggested the best battery combination;
"So far the best is TB48 + 2 x 2200mah 6S nano-techs.
It was about 55F during the test."
I am looking for max airtime and wondered if this is still the best combination?
I am flying an x5R
Could you please give me advise?
Kind regards
Hi Ralph, any news on the batt mod for Inspire 2 ?Damon is definitely on track. He is very knowledgeable in the battery mod world. I personally use dual 1850's but 2200's will work as well.

I meant more the way to connect the aux batts. Any progress on that. Best combo thereafter is a matter of try and error I guess.Still finding the best combo. Just a little more testing and I will be ready to release the info. The I2 is a different beast all together. A little more challenging to get perfect. I don't want to post the final until I'm 100 percent t sure it's solid. Will be soon. I'm in Texas this week at a DJI Expo testing the M210. Will be back on Friday.
Well, I think I'll let someone much more in tune with electronics figure this one out. I was really hoping the charging cable to the remote controller would clear things up with a nice and simple circuit, but it does not. Plugging the cable into the battery immediately turns on the battery. I took my multimeter out and measured the voltage at the end that plugs into the controller. 22.5V with a half charge. That's good news. Now to see if I can go backwards on this cable and send a current through it to charge the battery. Nope. It won't do it. Something is blocking the current going back into the battery. Took me about an hour, but I was able to dremel away the hard, rubber outer casing of the end of the charging cable that goes into the battery. It's another circuit board. That must be why the battery turns on when the cable is plugged into it. I couldn't follow that circuit board either. DJI is really doing their best to keep people from making the I2 more customized. My only hope is that the P4 battery setup is like the I2. I see all sorts of parallel battery charging stations online for the P4, so obviously someone has figured out the pin out for those batteries. I'm hoping someone does the same for the I2 so that I can make my own charger and add auxiliary batteries.
Thanks John for the detailed explanation of what worked for you! It answers some questions that I haven't asked yet!!I have been experimenting with different battery configurations and have achieved the following with my Inspire 1 v1 with X3 camera. TB48 plus 2 Turnigy Bolt 1300mah 6s in parallel, 20 mins to 30%discharge. With just the TB48 I get 15 mins maximum to 30%.
I then tried 2 Turnigy 6s in parallel nano tech 1550 mah and got the approximately the same duration as the 1300. Obliviously the extra weight of the 1500s out wade the slight increase in capacity. I then tried 2 Turnigy nano tech 2200man (6s) in parallel, a lot heavier system and recorded 23 mins to 30%. What I really wanted was higher flight times with the X5 camera an 17 mm lens. This is where the 2200 really score. With the TB48 and the X5 12 mins to 30% was maximum. Fitted with the 2x2200 I recorded 20 mins, even though this configuration is on the heavy side. Have'nt weighed it yet but it must be at least 1kg over the weight of the basic inspire 1 with X3.
20 mins to 30% with the X5 and lens is fine for my needs, so the Turnigy 2x2200 nano tech is optimum.
Hopes this helps, I have not tried to squeeze longer flights by going down to 10% discharge, possibly could get 30 mins but I doubt it.
