So what you are saying is that the battery could be charged just enough to move the servos while it reads 6 volts unplugged from the bird and when you plug it in and run servos the battery will show its true value? Forgive me ive been out of the hobby for about five years and am working and living in egypt for the past two years so its very hard to get the above described meters. Thank god for rcuniverse and all you guys with help!
The more servos attached to the Rx, the higher the load on the battery and the higher the Current Draw. If the servos are Digital, they will draw more Current and if they are Stalled, due to a mechanical problem or tight hinges, they will draw more Current than usual. It all adds up.
The ESV Load is designed to test the battery to see how it behaves under adverse conditions. There are also other testing devices that are even more predictive.
