Battery voltage boost step-up converter

This voltage boost step-up converter is very cheap (15€) and can be useful to:
• supply a higher voltage to the motor controller and motor than the one available on the battery pack
◇ may be good to test your system with an higher voltage, before you decide to buy/build an higher voltage battery
• the output current may be limited starting from 0.5A to the max possible value, so it can be used to test your system almost like using a lab power supply
• higher currents output: various units can be wired in parallel to sum up the output current

Disadvantages
• efficiency is listed as 95%, so at least 5% of power will be lost but this value can be even higher in worst conditions
• no regen: will not be possible to use ebrake/regen when using a direct drive motor

A DC-DC boost converter(example) can be used between the battery and controller to step up the battery voltage to present a higher voltage to the controller. (A 36V battery can be used to drive a controller&motor with 48V.)

But, those boost converters also have the possibility of supply their output voltage (settable to any voltage higher than the input up to some limit (80v in the case of the unit linked above) at a preset constant current from 0.5A up to their maximum (20A above). My random thought was that if during testing the firmware with a new version, you fed it via the boost converter, you could preset the current available to the controller to some low value initially and then once things appear to be working okay gradually step it up, thus protecting the controller output stages.

The booster simply won't let the controller draw more current than the value you preset, and if it attempts to, automatically falls back to some low value -- 5A is mentioned the linked modules blurb. That way, if anything goes wrong in the logic and the controller attempts to draw big current, you would get a heads up and avoid blowing your FETS.
