J.James said:Well the big problem with the "smart" battery's on board circuit is that they have a cell protection circuit in them. Which is a BIG TIME no no to do on any battery thats meant to go in to any thing that flys. its fine to have in a battery that runs some thing like a flash light were if the charge protection circuit cuts off the cell its not going to cause some thing to do a swan dive.
But there not so smart charge circuitry will cut off power going to or from any cell that ever fails below or ever goes over a certain cut off point. Some times if a battery is cut off if its just a tiny bit to high and triggers the cut off. It can repair its self if the battery self discharges over time and falls below the cut off voltage and then the circuit will again start letting power in or out of the cut off cell. BUT if it fails below the low cut off point there is not a thing you can do to get enough power back in to get the blocked cell changed. With out havering to open up the battery and charge the blocked cell up enough to get the protection circuit to unblock and then allow power to go to the cell again when charging.
BUT the people havering problems with all there battery's or getting non dji battery warnings. That's caused by some thing completely different and will even start happening to people that have the newer battery's with the square data pads . eventually. Its not the shape of the pad that is the problem and thus dji changing the pad will not change the cause of the problem. What is happening to them is over time they get an oxide layer on them and being the data pins are very low voltage and also very very very low amperage it dont take much dirt or oxide to causes them to stop making good contact and conducting to the data pins esp if some one still has the older round ended pins. and even they dont always ensure that you will always have a good electrical connection on the pads if the points dont scratch threw the oxide layer and make a good conductive path for the data pins. The pins and the pads need to be keep clean esp the pins if its happening on all of some ones battery's The pins also are just brass and dont even have a gold plating on them like the battery's pads do. So they will tend to get oxide on the pins more so then the battery's pads can. There is a very good product made for not only cleaning low volt and low amp contacts that also puts a protective conductive coating on them as well. Its called deox-it contact cleaner and restorer. Its great stuff and should be applied to the data pads on all the batterys and the pins every few battery's you run threw and also before ever planing on not using the battery's for a long time and also a good idea to use it if you are going to fly and have not done so in a long time. Its also great stuff to use on any low power plugs to make sure they have and keep having good contact and stay conductive. Sence I have been using it I have not had any more lost contact with the data pins or getting any false non dji battery warnings. I also some times do contract network installs and repairs and we have also started using deox-it on just about any low voltage plug to make sure we have no contact problems or data flow problems from dirty or old network plugs. ITS GREAT stuff I would put it in my coffee in the morning if a tiny 2ml bottle was not $9
BTW even a tiny 2ml sweeze tube GOES A LONG LONG LONG way. and a bigger bottle thats about the size of a bottle of nail polish and up wards of about 18-25 bucks would last a life time.
We used contact cleaner, a lot, when I was working. I don't recall that brand being out then, but we did switch to another product that accomplished the same thing.
Well designed plugs should have a wiping action that helps to reduce oxidation. Apparently, these are not.
