Just what the subject line asks...does anybody know if it's kosher to use a 3S battery (11.10 volts) in a Global Drone X183 (X6 Follower) that comes with a 2S (7.40 volts) battery?
I have found one (1) video on YouTube that appears to indicate that it's alright, but I'd like to read it from an expert who may be able to furnish a good answer before I actually attempt this on my drone.
Agree if capacity is the issue just increase mAh in the batteries but can be bad as well at some point weight overcomes thrust (trading agility/acceleration for hover time). If you want to know if it's safe to run higher voltage you'd need to check component by component to make sure they are all rated for that voltage or you're likely to fry something or with MCUs have the clock running at the wrong rate. You can check linear regulator data sheets since typically they're at the input point for battery power to get 5V and or 3.3V for ICs but the ESCs also need to have mosfets and capacitors rated to handle the voltage.
