here is the problem, I flew last thurs with four batteries, I need to fly tommorow, I have gone to put the four that I flew last week on charge as they were around 40% discharge. All four of them show the overheating flash when connected to the charger. (two flashes followed by a small pause and a third flash on the first LED) the four that I didnt fly are topping up with no problems, they have all been stored at the same temp, and are not over the heat threshold for charging. Perhaps the flashing light means something else in this case? perhaps I can do a soft reset on them? Maybe they still think they are at the temp they were at when turned off? either way I have 4 useless batteries and need to fly anyone got any ideas?
