Hello
@Dart67_SWE,
I am not sure about your formula for the Anafi battery.
I would have done the following calculations (but I may be wrong)
- Number Of cells = 2 on the ANAFI that is kind of a 2S drone, but each individual cell is limited to a maximum of around 3,8 V. The voltage you mention at the end for the formula does already include the fact there are 2 cells for a total of 7,6 Volts. It is also written in capital letters on the battery :
Charging Limiting Voltage 8,7 Volts.
- Rated Power I (A) = 2700 mAh. But also
stated on the battery discharge max 3A at 8C.
So I would say : 8,7 V max x 3 A x 50% charge (you can prove if you click on the button that shows 2 leds on the 4 possible leds) = 13 W
... still wayyy under the limits. and also easy to demonstrate before boarding (no mention of the 2 cells on the battery but the total of 8,7 Volts includes the fact there are 2 cells).
They generally ask for a 50% discharge that corresponds to the most stable chemical stability of LiPo battery.
As I am not sure safety agents are familiar with calculations on LiPo batteries. All battery manufacturer should add on the label in
Bold Characters
Cabin Bagage Safety Notice in accordance with IATA
- Max 27 W when charged at 100%
- Max 13 W when charged at 50% (two Led Lights on button check)
So we could travel without question at security check
