The quick reply is that in terms of flight occasions and motor efficiency, the upper a battery’s C score, the extra probably it is going to make you smile. A 45C pack makes a joke of a 10C pack in terms of energy supply. The C score 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 general capability. A battery that has a better C score delivers extra vitality, and meaning larger 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 beneath load. This means to take care of a better and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is notably essential when you could 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 can 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. A better C discharge score offers us that further “oomph” we take pleasure in in flight, irrespective of the airframe.
Though a pack with a better C score can usually be charged in much less time as a result of it may tolerate a better present charge, don’t be in a rush; you may all the time cost it at 1C (one occasions the capability), which is able to take about an hour for a whole cost. Doing this has produced the perfect leads to our expertise; we have now some older packs that also function nicely after
a whole lot of cost and discharge cycles.
