More flight one to enjoy, but holy different physic of flight.
Love these batteries, the have the best connector
Fit perfect in the standard battery slot
I used this battery in meteor75. A flight consisted to voltage 3.8V in about eight minutes. It is very good performance.
The 550 gives me +1 minute of slow flight comparing to 450 at Cetus X.
Note, native power wires are nearly feets. However I wiuld like it to be a bit longer
