Default RE: 6 volt battery question

At 6.4 volts, you still have 90% of your charge left, a perfectly normal occurance after a few short flights. You can safely fly down to 5.6 volts. Take a close look at DMcQuinn's graph, it is pretty typical. You will note that the voltage quickly falls to 6.4 volts then holds well above 5.5 volts for a long time. Get a Voltwatch (you can get them for 5 cell batteries) and it will warn you as when, at the end of a flight, it falls into the yellow it is time to charge. IMHO a Voltwatch is better than a loaded voltmeter as it is always connected and easy to immediately access the charge level at the end of each flight before turning off the switches.
