You could do-it-yourself. The theory is simple! You waste lots of energies
through frictions that can't be avoided in order to brake effectively. Now
there is a device that allows you to avoid those frictions, and this device
will add a strong friction back when you brake, automatically. It becomes a
5th brake to slow down your engine, a frictionless alternator and a normal
alternator. 3 modes in 1 automatically controlled by you and a device
algorithm. Voltage is easy to control, Current is not. That's why you need
this device, when you brake, it stores extra high current into your battery.
You can feel the torque after each brake or each deceleration consistently:
