I bought these to use on the Eachine Wizard X220 that I ordered here on Banggood. The Wizard came with a 3s, but this 4s really unleashes it's full potential. There is a HUGE difference between running 3s & 4s on a quad, just make sure your's can handle the power output. I have put about 15 cycles through these and they are still holding up great. I keep a close eye on the Voltage and never run them too low, as all lipo's should be monitored. I shut them off when the cells reach 3.6 volts each and charge them until 4.20 volts. So far, the run time is remaining constant. Happy with these batteries
