Hi! Sorry if this is the wrong section of the forum but I thought it was both mechanical and electric. But it also concerns the whole thing because I’m not sure about a few things. I’m also new to the forums and have a very basic knowledge of the engineering behind a lot of it.
So these are the base components at the moment. (Unfortunately I can’t link all the parts)
Longboard: Krown Krex 2 Bamboo (41 inches long) with 83mm wheels
Charger: IMAX B6AC V2 Professional Balance Charger Discharger
ESC: http://www.hobbyking.com/hobbyking/store/__28224__HobbyKing_120A_Boat_ESC_4A_UBEC.html
Batteries: (In parallel) 2x http://www.hobbyking.com/hobbyking/store/__15521__Turnigy_5000mAh_4S1P_14_8v_20C_Hardcase_Pack.html
Now to the motor, I would either be using a 400kv @ 1820watt or a 600kv @1030Watts. My question is whether or not the 600kv motor will have the needed torque with the 14.8V 4S 20C batteries I would be using.
I calculated a gear ratio of 1:3.33 @ 8,800 RPM on the 600kv motor with a top speed of 25 MPH.
Obviously this isn’t a full build and I’m missing a few parts, but purely to start with, I’m curious whether I can use this 600kv motor and the batteries in parallel or if I would need more voltage. Also, what kind of range I would be getting with this setup is a complete unknown to me. Electrical engineering is not really my area of expertise, haha.
Thanks for reading and any advice/criticism is much appreciated.
