Is there a battery replacement for my L4 that will give me a longer running time?
There isn't room onboad for bigger batteries. But you can cheat by constructing a two wheeled trailer just big enough to hold two more batteries they can be as big as you want. When the on-board batteries get low flip a switch and your running on out-board batteries. Be sure the trailor is conntructed to be as lite weight as possible. you can buy trailers for scooter. I did it the lazy way, I wired my external batteries directly to my internal battery terminals due to amp loading.If they are lets say 50amp to your 15amp on- board batteries you are going to go way more miles than with15amp batteries. WARNING this setup you don't hook fully charged big batteries into discharged small. batteries. I don't let my on-board batteries get to discharged. I've spliced into the main battery terminal lines..so that they are thick enough to handle the amp load which are 12 gage. I also have a 50 amp connector between the external scooter and the trailer for quick disconnect

When I drive forward and move the joystick to center the chair is still moving for the few fit before stops.
If the brake is applied by electromagnetism, power must be supplied to the coils by either manual or electronic switching.
I suggest you investigate the circuit to discover how the power should be supplied to the brake coils and then it will be easier to trace the fault.
As a matter of not unrelated interest, it is fairly usual to arrange the wiring/switching so when power isn't being supplied to a low voltage DC motor the motor terminals are shorted. When being pushed the motor becomes a generator and the input becomes and output and so shorting that output makes the motor self-braking to some extent - this is why car windscreen wipers are able to stop almost instantly...
