The quick reply is that in the case of flight instances and motor efficiency, the upper a battery’s C ranking, the extra possible it’s going to make you smile. A 45C pack makes a joke of a 10C pack in the case 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 the next C ranking delivers extra vitality, and meaning greater efficiency. The large distinction between batteries with totally different C scores is the truth that the higher-rated batteries endure much less from voltage drops beneath load. This means to take care of the next and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is notably vital 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 can help you 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 may 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 provides us that additional “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 could possibly tolerate the next present fee, don’t be in a rush; you may at all times cost it at 1C (one instances the capability), which can take about an hour for an entire cost. Doing this has produced the very best ends in our expertise; now we have some older packs that also function properly after
a whole bunch of cost and discharge cycles.
