i have to say that i am in love with your bm3. only reason why i don't make one is lacking of founds. I have a few questions about its design.
i noticed that Roboteq cd controller. is placed under the seat.
what happens if with cd controller if somebody fails or god forbid roll over, also what happens with battery cells.
to cells and controller fell apart to million pieces or can somebody help you to get back in chair and drive away like nothing happened.
I manage to fail several time with my wheelchair and my scooter.
