Hi, I am doing some research to ev-convert my Yamaha xmax250. I want to install a 12kW DC brushless motor running at 72V. From what I've read good options may be Agni143, LMC-LEM200, PERM PMG132 or PMS150. Also ME0913 and Goldenmotor as more economic options. What would you suggest as a best balance in terms of cost and performance? Thanks!
