Hi guys
Phantom 4 adv. +
Installed (2x) 4c LiHV 4000mah battery’s onto the phantom 4

Link for battery:

(2x) 4000 mah. gives the phantom a BIG 8000  mah. extra battery mod. together with the high capacity 5870 mah.

Flight data:
1.
In the air for 35 min full throttle all the time (sport and p mode)
Temp. was only 2 degrees C. so I expect something like 10-15 minutes more flight time at 20d C. in the spring.

2.
4k 60 fps. video on all the time.

3.
2x LiHV 4000 mah. charged to 4.25v pr cell (so 17v . pr LiHV in total)

4.
High capacity Batt charger full Lipo 4,20 V. pr cell (so 16.80 v. total)

Hope you enjoyed this video :)
