The quick reply is that in terms of flight instances and motor efficiency, the upper a battery’s C score, the extra seemingly it can make you smile. A 45C pack makes a joke of a 10C pack in terms of energy supply. The C score 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 score delivers extra power, and meaning increased efficiency. The large distinction between batteries with totally different C rankings is the truth that the higher-rated batteries undergo much less from voltage drops underneath load. This capacity to take care of a better and extra constant voltage is what sometimes generates the excessive efficiency we take pleasure in. That is significantly necessary when you have got 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 will 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 larger (or extra) motors in your multirotor for elevated length and/or payload-lifting capabilities. The next C discharge score provides us that additional “oomph” we take pleasure in in flight, regardless of the airframe.
Though a pack with a better C score can typically be charged in much less time as a result of it could actually tolerate a better present price, don’t be in a rush; you possibly can all the time 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 most effective leads to our expertise; we’ve some older packs that also function nicely after
tons of of cost and discharge cycles.
