Running a Flipsky FSESC4.20 Plus with 13S battery

Hey everyone. I have a Flipsky FSESC4.20 Plus, it is rated to 60V and 100A. Is it possible to use this with a 13S battery, which has a max voltage output of 54.6V and 30A. According to the rating of the controller it should be fine, but after reading about other peoples experiences with this controller on this and other forums I am getting the impression that it is not going to hold out for very long.

Controller info:

  • Current:50A continuous/single, 100A continuous/dual ,burst 150A/single, burst 300A/dual
  • Voltage: 8V-60V (Cells: 3-13S LiPo,Safe for 3S to 12S LiPo, Voltage spikes may not exceed 60V!)

The part where it says ‘Cells: 3-13S LiPo,Safe for 3S to 12S LiPo’ is very confusing. It can take 13S, but it’s not safe? Why is it rated at 13S in that case?!

Thanks for anyone who can help!

No. 13s will blow it up. Many tried. The numbers is just saying its based on the rated voltages, but it cannot handle voltage spikes from 13s.

Thank you LeonCamero. Would you recommend running 12S or 10S with this controller?

10s for safety. I’ve read that 12s can cause it some issues. Not often, but its flipsky.

Thank you LeonCamero :+1:

They run 12s fine just keep the motor kV 170 and under.
