I had a set of I2 batteries that had an issue before the firmware update came out that was supposed to fix them. They had been sitting for a pretty good long time, but one of them was about two and a half lights on the battery level lights and the other was it about two lights. I had them labeled so I could always put them in the exact same side of the copter when I used them. Also, I labeled one of them with a sticky note Scotch taped to it that said it had the error in it. The error I think was that one of the cells was way higher than the others apparently, seen on battery 2 in photo below, and it would not charge and threw an error code in the go 4 app. When I hook them up to charge them, the battery with the error code won't charge fully, the other one will. This is a pic of go4app battery levels showing battery 2 error, and sixth cell with a way higher level. Might be something else throwing the error, but whats obvious? The other battery, battery one, looks good and always did, and never threw an error.
So a week ago, I updated the copter and these batteries with the current firmware and all my other batteries as well, which never had any problems. I had the two problem batteries in the screen above, set to 10 days discharge time on each one, and after the firmware update, the one with the error code still would not charge up. So I waited over three days like I read to do about the situation, and today, about 4 days later, I put them back in the copter to check the status. The one battery with the error code had now leveled out all of the different cells to about the same charge level. And the other battery was looking pretty good as it always had. Neither one of them threw any error codes. I didn't take a photo of the screen at the time though.
So I put them on the charger and they charged up until both the green lights were on solid and they were through charging. I put them back in the copter and the one that had the error code initially, started showing the error code again. The other battery was okay. They were in the exact same slots or sides of the copter that they always were put in. So I turned the copter off and had the idea to switch the batteries from one side to the other, and when I did this, the battery that had the error code was fine with no error and the levels were looking almost perfect, and the battery without the error codes in it now had an error code thrown. Then I switched them back to the original slots in the copter, and the battery that had always been the good one still shows an error code on it and the battery that always showed an error code now has no error code. The battery that was always a good battery shows levels up and down, varying several volts from cell to cell. This photo below shows the batteries in original slots on copter in first photo and switched in the second photo. The battery showing the error in both photos WAS the good battery.
After I went and ate lunch, I came back to the batteries again and put them back on the charger. They both are showing fully charged on the battery charger, both green lights solid, except the battery which was always good, shows the error code no matter which slot in the copter I put it in, and the battery that was always bad showing an error code, is now beautiful. I'm 100% positive there was no mix up in which battery was the good or bad one. I have a sticky note Scotch taped to the one that always had an error code on it, and they are labeled for the slot that I always put them in on the copter.
And the question arises in my mind, have I ever dropped a battery on the floor or done something to deserve such punishment? As you can see in the pictures of the battery levels, one battery has been charged four times and one five times. Never crashed the copter, or done what some people would say is hard landed It, which I call a light crash. A hard landing is a crash, I don't care how you want to split hairs. I'm thinking about hard landing it though, put it in sport mode and fly it into a **** brick wall. Probably will fix the whole **** thing.
So now I am developing a new product for sale. It is a full helmet that covers all of your head and hair, so that you do not pull all of your hair out dealing with this BS. I remember the wonderful days of having regular old LiPO batteries with a balance charge plug and a deans connector on them.
But the more exciting news is that after this firmware update and everything is updated and looking great, except for these two batteries, I put the propellers on the copter, put it on the ground and got all the satellites around the world linked up to it, fired it up while holding it on the ground just to go with the hunch that there might be a problem looming, and as I'm holding the copter on the ground and fire it up, I move the left stick up from center idling position and the thing is wide open as soon as you move the throttle stick upwards from center any amount. So its now either idling or wide open. So I think if I had have taken it off and try to fly it, it would be somewhere around Saturn or Pluto by now.
Anybody got any ideas on this?
