The batteries are not from the same manufacturer as in the order, but it would not matter if these batteries were of good quality. All batteries do not meet the declared load of 30C (4.5A for 150mAh) and instantly sink to zero on loading. The flight time on such batteries will be about 2-3 minutes, instead of the prescribed 7-8 minutes. It is trash for the trash can. I returned the money through a dispute.
