The brief reply is that relating to flight instances and motor efficiency, the upper a battery’s C ranking, the extra seemingly it should make you smile. A 45C pack makes a joke of a 10C pack relating 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 increased efficiency. The massive distinction between batteries with totally different C rankings is the truth that the higher-rated batteries endure much less from voltage drops below load. This skill to keep up a better and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is notably necessary when you could have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely will let you 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 can ship (in our 2000mAh instance) 60, 90, and 140 amps. This main enhance in present permits us to run greater (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. The next C discharge ranking offers us that further “oomph” we get pleasure from in flight, irrespective of the airframe.
Though a pack with a better C ranking can usually be charged in much less time as a result of it might tolerate a better present charge, don’t be in a rush; you may all the time cost it at 1C (one instances the capability), which can take about an hour for an entire cost. Doing this has produced one of the best leads to our expertise; we now have some older packs that also function effectively after
a whole lot of cost and discharge cycles.
