The brief reply is that in relation to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra probably it should make you smile. A 45C pack makes a joke of a 10C pack in relation to 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 larger efficiency. The large distinction between batteries with totally different C scores is the truth that the higher-rated batteries undergo much less from voltage drops beneath 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 occasions 2000mAh equals 20 amps). A 20C pack of the identical capability will safely can 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 greater (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. A better C discharge ranking offers us that additional “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 could actually tolerate a better present fee, don’t be in a rush; you possibly can all the time cost it at 1C (one occasions the capability), which is able to take about an hour for an entire cost. Doing this has produced the most effective ends in our expertise; we’ve got some older packs that also function properly after
lots of of cost and discharge cycles.
