Smart BMS with bluetooth

BMSBattery Q75

Q75 Front-driving High Speed E-Bike Hub Motor
Packing list:
A 36V Q75 motor.
Efficiency: 80%
Fork size: 100mm
Hall Sensor: Sensorless
Max. Torque: 40N.M
Power: 200Watts
reduction ratio: 13.4
rotor alnico number: 16

Weight: 1.2Kg
Note: Only S06P and LSW-675 controller fits this motor.

S06S controller: P1 = 214

I am using Q75 with LSW-675. Works great.

Re: Pairing Q75 motor with LSW-675 controller
WARNING: DO NOT USE S06P controller with Q75

Changed the S06P to LSW-675 and it works flawlessly with Q75.
BMS battery is making false claims that S06P is compatible with Q75!!!

• RPM 328
• RPM 201

328RPM version
• rotor RPM = 328 * 13.4 ~= 4400RPM
◇ eRPM = 4400 * (16 / 2) = 35200 eRPM

The maximum RPM when running with hall sensors is much higher, but at values
over 40,000 eRPM the commutation timing can be off and motor performance will
suffer.
