from the left 8000 mah thunder power battery 593g 6400 mah venom battery 488g 5000 mah battery 385g 3200 mah PQ battery 272g 2800 mah zippy battery 219g 2700 mah thunder power battery 188g 2700 mah storm battery 188g 2500mah battery 181g 2200 mah stock battery 175g I use all these batteries on my phantom (mostly in pairs, including the 2800s) I've even tried the dual 3200s but they were too heavy and made the phantom too sluggish and heavy coming down. The 2800s work well, but the storm 2700s will fly just as long. One phantom is 1160g and fairly clean, does have dual batteries and retracts (no camera, etc.) with CF vision blades. The other phantom is 1450 and has everything (dual 2700 storms, iosd, fpv, CF landing gear, upgraded motors) with tri blades. Both phantoms are using Naza M but i just bought a V2 and antenna puck, pmu, etc for the one that is stripped down. I use dual 5000s, 6400s and a single 8000 on my F550 which is also pretty loaded and heavy 2730g with the 8000mah(iosd, fpv,cf landing gear with retracts, hero3 black, tarrot gimble) etc. this has the naza V2 already. Lots of fun when the weather cooperates!
