The quick reply is that in relation to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra probably it’ll make you smile. A 45C pack makes a joke of a 10C pack in relation to 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 the next C ranking delivers extra vitality, and meaning greater efficiency. The massive distinction between batteries with completely different C scores is the truth that the higher-rated batteries endure much less from voltage drops beneath load. This potential to take care of the next and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is notably essential when you might 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 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 greater (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. The next C discharge ranking provides us that further “oomph” we take pleasure in in flight, regardless of the airframe.
Though a pack with the next C ranking can typically be charged in much less time as a result of it may well tolerate the next present price, don’t be in a rush; you possibly can at all times cost it at 1C (one occasions the capability), which is able to take about an hour for an entire cost. Doing this has produced one of the best leads to our expertise; we have now some older packs that also function nicely after
a whole bunch of cost and discharge cycles.
