The quick reply is that on the subject of flight instances and motor efficiency, the upper a battery’s C ranking, the extra seemingly it should make you smile. A 45C pack makes a joke of a 10C pack on the subject 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 general capability. A battery that has a better C ranking delivers extra vitality, and which means 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 a better and extra constant voltage is what sometimes generates the excessive efficiency we take pleasure in. 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 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 may ship (in our 2000mAh instance) 60, 90, and 140 amps. This main improve 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 provides us that further “oomph” we take pleasure in 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 will 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 a whole cost. Doing this has produced the perfect leads to our expertise; we have now some older packs that also function properly after
a whole lot of cost and discharge cycles.
