Went to my favourite hill this morning with the new Mini 3. Charged everything up as usual the night before except for the Tripltek tablet which was indicating 60+ % battery level. Thinking all would be ok I flew 2 batteries with the Mini 3 which was about 40 minutes total flight time then landed for the third battery. As I was landing a low battery warning came up on the Tripltek tablet. I shut the Mini 3 down and checked the Tripltek battery level. 1% was all that was left!! Never had this before. Normally the Tripltek battery lasts a long time. So can’t think why it dropped so suddenly with only approx 40 minutes of flight time? Of course I am going to fully charge it every time I go flying from now on! Lesson learnt!
