The brief reply is that with regards to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra possible it should make you smile. A 45C pack makes a joke of a 10C pack with regards to energy supply. The C ranking for a LiPo battery, fairly merely, refers back to the capability of power the battery can safely discharge, represented as a a number of of its total capability. A battery that has a better C ranking delivers extra power, and meaning larger efficiency. The large distinction between batteries with completely different C scores is the truth that the higher-rated batteries endure much less from voltage drops below load. This capability to keep up a better and extra constant voltage is what sometimes generates the excessive efficiency we take pleasure in. That is significantly essential when you could have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 occasions 2000mAh equals 20 amps). A 20C pack of the identical capability will safely mean you can draw 40 amps from it repeatedly. That’s the identical capability and twice the amp draw. There are battery packs on the market rated at 30C, 45C, and even 70C that may ship (in our 2000mAh instance) 60, 90, and 140 amps. This main improve in present permits us to run greater (or extra) motors in your multirotor for elevated length and/or payload-lifting capabilities. A better C discharge ranking offers us that further “oomph” we take pleasure in in flight, regardless of the airframe.
Though a pack with a better C ranking can typically be charged in much less time as a result of it might probably tolerate a better present fee, don’t be in a rush; you may at all times cost it at 1C (one occasions the capability), which is able to take about an hour for a whole cost. Doing this has produced the perfect ends in our expertise; we’ve got some older packs that also function effectively after
a whole lot of cost and discharge cycles.
