Size maxx for LIPO on CRT.5 Pro conversion

[rexasso]

In fact my HV ESC has burnt, so when I say HV 5.5 it is for the motor only.
HV Pro 5.5 motor is a 36x72mm with 3700kv motor, so I think it could take place of a medusa 36-70.
For sure it will be a lot of power, but I planned to use exponential parameter for curve on my 3PM radio
About the ESC, I think I will try the HobyCity 100A
It will be in 3s 5000mah lipoly.
Should I use 2s ?

What do you think with this configuration ?
