The quick reply is that in terms of flight instances and motor efficiency, the upper a battery’s C ranking, the extra seemingly it would make you smile. A 45C pack makes a joke of a 10C pack in terms of energy supply. The C ranking for a LiPo battery, fairly merely, refers back to the capability of vitality 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 vitality, and meaning larger efficiency. The large distinction between batteries with totally different C rankings is the truth that the higher-rated batteries undergo much less from voltage drops underneath load. This capability to take care of a better and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is notably necessary when you will 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 can 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. The next C discharge ranking offers us that additional “oomph” we get pleasure from 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 tolerate a better present fee, don’t be in a rush; you’ll be able to all the time 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.
