[QUOTE="Chrislaf, post: 101032, member: 3317"] Thanks all for your replies. The battery in question has 74 charge cycles on it and will be 2 years old in January. The battery is displaying normal temps on landing and has no visible swelling. I put the battery in my Spark and brought up the battery info in GO4 and everything appears normal - cells, voltages and GO reports no problems. I compared the clips on the battery to my newest battery and the clips appear to be the old style that have been the source of batteries coming out during flight problems reported on this forum, so for this reason I do not want to do a flight without my battery strap. Also, when the battery is inserted into the Spark the battery button works normally and the battery can be turned on and off normally. I'm thinking that the battery is coming slightly loose during flight but not enough to disconnect and pushing back against the battery strap so that is why the button and lights get messed up. If this is happening then it is only a matter of time before there is a disconnect during flight. When I get some time later today, I will contact DJI to see what they have to say. In the meantime, I will not fly with this battery until I get to the bottom of what is causing the 4 lights to flash and the battery button to not work properly after a flight. Chris [/QUOTE]
