The quick reply is that in terms of flight instances and motor efficiency, the upper a battery’s C ranking, the extra probably it can 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 general capability. A battery that has a better C ranking delivers extra power, and which means greater efficiency. The massive distinction between batteries with totally different C scores is the truth that the higher-rated batteries endure much less from voltage drops below load. This capability to keep up a better and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is notably necessary when you will have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely assist you to 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 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 further “oomph” we get pleasure from in flight, regardless 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 may at all times cost it at 1C (one instances the capability), which can take about an hour for a whole cost. Doing this has produced the most effective ends in our expertise; we’ve some older packs that also function nicely after
lots of of cost and discharge cycles.
