The quick reply is that in the case of flight instances and motor efficiency, the upper a battery’s C ranking, the extra doubtless it should 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 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 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 below load. This capacity to take care of a better and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is notably essential when you’ve gotten 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 let 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 can 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 length and/or payload-lifting capabilities. The next C discharge ranking offers us that further “oomph” we get pleasure from in flight, irrespective of the airframe.
Though a pack with a better C ranking can usually be charged in much less time as a result of it may possibly tolerate a better present fee, don’t be in a rush; you’ll be able to at all times cost it at 1C (one instances the capability), which is able to take about an hour for an entire cost. Doing this has produced the perfect ends in our expertise; we now have some older packs that also function properly after
lots of of cost and discharge cycles.
