@iENYRID @akasoofficial Here is a second test with the AKASO EK7000P action camera using resolution 720p -120fps with stablisation on, also using AKASO V50 External Microphone due to the internal microphone is weak when in motion (previous video) I kept the iENYRID M4 PRO S+ on MAX trottle power / gear 3 to test the range and voltage which seems to use 1 volt every 2 miles but this will all depend on power output to get the maximum distance out of one full charge which is said to be over 30 miles! on top speed my calculation is one full charge should get 18 miles (maybe 24) but again power output plays a part in this. Full charge voltage is just over 54v and battery runs out around 40v but starts to reduce in speed around 44v.
