Series or parallel connection for drone batteries?
Batteries in series = add the voltages, ie two 3S 1300 30C packs becomes 6s 1300 30C. Batteries in parallel = add the capacities, as above you get 3S 2600 60C. There''s no particular pros or cons for either, many larger commercial drones use combinations of packs in series and parallel to get the power source they need.
