Have a question and any input from experience would be appreciated:<div>My batteries (two of them) started acting-up. If you saw Graphite videos - on lunch I have a voltage drop (and transmitter buzzer goes off) which becomes normal once battery warms-up under load in the air.</div><div>After last flight day I plugged the batteries to balance and one showed 4.20/3.98/3.96 V in cells. I rejected this battery and ordered a replacement.</div><div>I useBlue LiPo 3S 2650mAh from Hobby Partz. Bought it 8 months ago and did not use them that much. Always took care of them, never over discharged. How can battery go bad that fast? I had about 20-30 flights on it.</div><div>
</div><div>Also when I power-up the first time on the battery - motor needs to spin for a few seconds before it gets a full power. I wonder if it is a battery or an ESC?</div><div>Thanks for your input!</div><div>Mark</div><div>
