Help me Configure my Flipsky 4.20 Plus

Running Samsung 30Q in 10s5p. Flipsky 4.20 Plus

Flipsky 6374 190KV motors.

*also running Charge only BMS I think 50amps or 40amps.

If my math is correct 15amp (per cell) x 5=75 amps for Battery Current Max. Am I right?

Yes correct 75 amps for battery should work fine.
