Tested on a Quad 4 inches with EMAX ECO 1404 3700KV motors; calm flight for almost 15 minutes. So rather satisfied. The batteries arrived with their storage voltage of 3.8V, however, the internal resistance measurement is close to 30 milliOhms: not very good, it seems to me, worrying for their lifespan. Sent out quickly and properly packaged.

Testée sur un Quad 4 pouces avec moteurs EMAX ECO 1404 3700KV ; vol tranquille sur presque 15mns. Donc plutôt satisfait. Les batteries sont arrivées avec leur tension de stockage 3,8V Par contre la mesure de la résistance interne est proche de 30 miliOhms : pas très bon il me semble , inquiétant pour leur durée de vie. Envoyées rapidement et correctement emballées.
