The quick reply is that in the case of 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 in the case of 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 which means 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 potential to take care of a better and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is notably vital when you have got 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 help 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 may ship (in our 2000mAh instance) 60, 90, and 140 amps. This main enhance in present permits us to run larger (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 get pleasure from in flight, irrespective of the airframe.
Though a pack with a better C ranking can typically be charged in much less time as a result of it could tolerate a better present fee, don’t be in a rush; you possibly can at all times cost it at 1C (one instances the capability), which can take about an hour for a whole cost. Doing this has produced the most effective leads to our expertise; we have now some older packs that also function effectively after
a whole lot of cost and discharge cycles.
