How to choose a UAV battery?
When fly your Phantom, have you ever met this problem ? that during closed-loop control, the Phantom drops height all the way. It is probably because of the low quality battery. The battery cannot discharge steadily ,so ESC unable to speed up. Or even worse, the battery explode into a fire. I am sure you must see somewhere.
So how to choose a drone battery? This is a big question. Firstly, how can we know the battery is good or not?
Under same condition, good battery charge very fast; disqualified battery take long time but still cannot be fully charged.
When discharge at high current, voltage of good battery will not drop suddenly, but disqualified one will.
When stop high current discharging, voltage recover of good battery is small, but disqualified one will recover a lot. For example, the voltage is 3.5V for discharging, it goes to 3.8V right after stop.
One great way to find out what the best battery is to look at graphs of the batteries performance. Looking at how low the voltage of the cell drops at various amperages will give you a metric to compare that battery to similar size/weight batteries.
What makes a good battery? It is decided by the raw material of positive & negative poles , the electrolyte, as well as the production process. The raw material of Tattu professional unmanned aerial vehicle battery is collected from the Top company.
