    Hey guys .. Just double checking here but I took my p3a out for a couple flights a few days ago it was fairly cold. These major deviations could be attributed to the cold & aggressive flying ? Or do you think this is 2 faulty batteries? Outside temp was prob -5C

    Min batt temp - 18.95C Max batt temp 32.95C

    Wait and see what happens on a warmer day. Don't fly with them before you confirm they are ok. My guess would be the weather, but don't go to any heights before being sure they are good.

    Yeah I'm thinking the same .. They are brand new ... Only 2 cycles on these 2 so .. I'm guessing the cold

    No need for concern at the moment.

    Especially battery two. One 75mv variation 11 seconds in to the flight only. Fairly common to see when battery first put under load at launch.

    No doubt you read the healthy drones guidance on this report. Perfectly good batteries can report several variations per flight.

    I would be looking at the usable mah and flight times. Keep an eye on things. Relax and fly.

    I had the same problem with both batteries I bought for my new P3P. I ran them down below 8% and then fully recharged them to 100%. I have not had the deviation problem since.
