I think it is easy to say that the dji smart battery isn't so smart. As it is, it counts the number of days and can provide a drain after a set number of those days. What is can't do, but should be able to do, is supply the P3 with enough power to perform as it should. We pay the crazy price of around $150 for a battery that is anything but smart. Anyone flying below 70f degrees will be faced with a near 41% reduction in speed. No...let's not set the battery up to supply the aircraft the power it ask for. And the reason for this is because the way they have had the batteries set up, it caused the temps to rise and be the blame for another jacked up part which is the body, as in motor mount area. So we now have batteries that almost double the price we were paying just before the P3 was released. The smart batteries have their own firmware. For what? To have internal calendars to begin a drain cycle? Seriously...the smart battery is simply a ripoff. These batteries were a reason why we couldn't use the multiple batteries we already purchased for the P2V+'s. We had to be required to start over and reinvest to a different battery setup. Surely, there is a better option that is less expensive, and not prone to dropping aircraft out of the sky?
