The quick reply is that in terms of flight occasions and motor efficiency, the upper a battery’s C ranking, the extra possible it is going to 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 power 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 power, and which means larger efficiency. The massive distinction between batteries with totally 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 take pleasure in. That is significantly necessary when you could have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps constantly (10 occasions 2000mAh equals 20 amps). A 20C pack of the identical capability will safely mean you can 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 larger (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. The next C discharge ranking offers us that additional “oomph” we take pleasure in in flight, regardless of the airframe.
Though a pack with a better C ranking can typically be charged in much less time as a result of it may possibly 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 can take about an hour for an entire cost. Doing this has produced the perfect ends in our expertise; now we have some older packs that also function properly after
lots of of cost and discharge cycles.
