First, the Lipo-free service properly and increased the flight time by 2-3 minutes. The batteries give their power from non-linear and therefore you realize towards the end as the power of the engines with the power output of Lipos drops.
so far so good. But after about already 5-8 charging operations begin Lipos to weaken and the maximum flight time breaks rapidly. Meanwhile 2 of 3 Lipos have been singled out because this only capacity for approx 1 - provide 2 minutes of flight time.
The third is slowly but surely also his mind and will soon be disposed of.
In comparison, I got me another 205mAh battery of another brand, which offers significantly more air time and as the original battery adduced no performance degradation after repeated loading.
Here I advise clearly from the purchase and recommend the 205mAh battery of the German manufacturer Mylipo!
