OVONIC 6S LiPo Battery 5000mAh 22.2V 130C RC Battery with XT60 Connector

I picked this up thinking that these would do a great job of powering my 5" FPV Drone. It can. But it's hilariously large when mounted to the drone. The drone needs to maintain about 40% throttle to stay aloft and I worry about the flight time (and weight) of the drone.I can't wait to try this out a second time, and a third, and beyond! The battery itself while not being used to fly my drones will absolutely work well on my large 2 meter wingspan FPV plane. It also works well as a larger power source to plug into my charger and use this to charge other batteries while out in the field. I even plan on getting a battery management system and using it with an inverter to run some of my other hobbies.

I've tested the capacity of these batteries and they fall a little short but not by much (they are 92% of stated capacity). I was able to put 4590mAh of into them. The internal resistance is low and consistent from cell to cell. I gave them 5 starts because the stated capacity was within 10% of actual capacity, which is better than most batteries out there. You could probably get 5000mAh if you charge and discharge at a lower rate. My testing was done at a 1C charge and discharge rate.My testing is as follows: I discharge the batteries to 50% charge (3.84V per cell) the fully charge the batteries to 4.20V per cell at a 1C charge rate. After charging, the voltage drifted down to ~4.18V per cell with no load.
