The quick reply is that with regards to flight instances and motor efficiency, the upper a battery’s C ranking, the extra probably it would 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 general capability. A battery that has a better C ranking delivers extra power, and meaning greater efficiency. The large distinction between batteries with completely different C rankings is the truth that the higher-rated batteries endure much less from voltage drops underneath load. This capacity to take care of a better and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is significantly vital when you could have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps constantly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely assist you to draw 40 amps from it constantly. 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 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 provides us that additional “oomph” we take pleasure in in flight, regardless of the airframe.
Though a pack with a better C ranking can usually be charged in much less time as a result of it could actually tolerate a better present price, don’t be in a rush; you may at all times cost it at 1C (one instances the capability), which is able to take about an hour for an entire cost. Doing this has produced the perfect leads to our expertise; now we have some older packs that also function nicely after
a whole bunch of cost and discharge cycles.
