Hi guys, Been flying for a fairly long time now. Still at a bit of a loss when it comes to batteries though. I have not been taking as much care with them as I should have been (leaving them with charge in etc) I have a cpu balance charger now so can now put them into storage mode. However a few of my old batteries must be starting to die because of this now... http://www.flytrex.com/mission/quadcopter-joes-fc40-joseph-somerwill-gkr2EJFV/ See the voltage on this flytrex. It dropped very fast straight away so I guess that means that the battery is on its way out? I guess what I'm asking is, is there a way to determine how much life the battery has left in it other than estimating based on flight times and flight voltages? I have a battery checker which can see individual cell voltages. Will this tell me anything? Thanks in advance!
