The brief reply is that in terms of flight occasions and motor efficiency, the upper a battery’s C ranking, the extra doubtless it’s 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 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 greater efficiency. The massive distinction between batteries with totally different C scores is the truth that the higher-rated batteries undergo much less from voltage drops below load. This capacity to take care of a better and extra constant voltage is what sometimes generates the excessive efficiency we take pleasure in. That is significantly 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 larger (or extra) motors in your multirotor for elevated length and/or payload-lifting capabilities. A better C discharge ranking offers us that further “oomph” we take pleasure in 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 will probably tolerate a better present price, don’t be in a rush; you’ll be able to 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 very best ends in our expertise; we now have some older packs that also function nicely after
tons of of cost and discharge cycles.
