Uneven Batt voltage draw
I have a smart fly EQ10, Smart Fly Pro, and Sport all on A123 direct with no regulator plugged into my Airtronics 2.4 10channel and 8 channel receivers and they work flawlessly. No problems noted. However I noticed on my 39% plane running 8 JR 8611a servos I was getting uneven amperage draw on one of the batteries. I decided to add another pack (I run all A123 with no regulator) and this solved the problem. Now I recently put my Smart Fly sport into use on one of my 50cc planes running all analog high power metal gear servos and again with my 8 channel 2.4 receiver. All works great but again I am experiencing uneven current draw. Is this normal ?
