I am building an electric skateboard for college this summer and I need some help.
These are the parts I am using: -Turnigy sk3 245KV -Samsung 30Q (and two goups of LG HG2) cells in 10s3p configuration -10s BMS from Mboards.com https://www.mboards.co/collections/diy-supplies/products/10s-bms-battery-management-system -ESC from Mboards.com (comes with remote) https://www.mboards.co/collections/escs/products/single-belt-driven-motor-esc -Caliber II trucks -Abec 11 83mm flywheels -32" cruiser deck -36t wheel pulley -16t motor pulley
I completed my build today only to find that I could barely pick up any speed. I cannot even ride my board up my driveway. I am not using a sensored motor in my build, however it does start without a push. I am thinking maybe the ESC is not able to supply enough current to the motor but I am not sure, I realized after purchasing it that it’s a piece of crap from China. My batteries are soldered together with nickel strips and squished together inside my enclosure. Has anyone had similar problems? Is it my speed controller? Battery? I assume it’s not the motor since many people have reported going 20+ mph with the turnigy sk3 245kv. Also my board pretty much has no braking power. I can get going on flat surface to about 10mph but I can barley stop and I have to jump off the board. I am thinking my speed controller is crap but since I have never done this and Mboards isn’t responding to my emails I’m not sure what the problem is.
