Hey pilots. I extracted battery voltage info from flight log with csview and plotted voltage in mV (y axis) vs time step. The time step is just 1,2,3... Real time is kinda obscure in the log file (help me decipher that if you are in the know please).

I compared a sefu battery and a fullymax battery from 100% takeoff to 0% landing. The sefu seem to be... Considerably less good.

Some more prop guard less indoor hover test , time recorded at 20% and 0%.

I weighed my SEFU, only 24g. Fullymax is 26g. This could be why?

Thx for sharing, some interesting data there.

Thanks for sharing the information!

I turned the sefu in at the retailer and got a fullymax one. The new battery is as good as they other 3 i already own and weigh the correct amount. Maybe I just had an odd ball, but I certainly will be watching out for those sefu ;)

Thanks for posting the information!
