1500w Brainpower motor controller for E-bike with handle bar with LCD screen

Perfect upgrade for any e-bike set up, particularly personalized bikes made by hobbyists such as myself. My hub motor kit came with a 1000w 48v hub and 48 volts nominal battery(52v max). Went 30mph with a 180lb adult. This will add 1500watts which increases torque(bottom end) by 33% which in WV hill climbing is part of life, so torque is more Important in my case than top speed. Voltage is probably the most expensive thing to add bc batteries determine that and anything larger than 52 V max is expensive. I’m asking 60$ for this almost brand new controller.
NOTE: check your brand and the wire configuration
