Hello everyone. I have a query about a very economical configuration that I have made. I have an 8" mountainboard and I have mounted an Esc + a 7s 1p battery that I had from a old skate with a hub motor. It is a Esc very similar to the ones sold in Diyeboard. To have more power I have added 4 units in series. 18650, total 11s1p, the engine is a 6368 190 kv sensored and the pulleys are 60-20 teeth, and I get a speed of about 25 km / h on the flat.The problem comes when there is an inclination, even if it is small, with a road of 3% inclination the speed is reduced to 10 Km/h and I do not know what would be the solution to obtain high speeds in mountainous or with high inclinations
I have tried other configurations of pulleys, 60-15 and 60-12 but the speed and torque is even lower.
What solution would you do? Thank you very much and sorry for my English.
