The car is for use in electric R/C stuff like cars and the like. It's not intended to help with the low power problem but rather the noise generated by electric motors. It acts as a noise filter, NOT as a voltage storage device. BAX has stated this in numerous threads in the past.
Yah, the more I read about it the more that became apparent. It also is sold in the car section on Horizon's site, not the air section.
They do show it as a means of protection from low voltage though:

The cap will store electrical energy and hopefully dampen the voltage fluctuations I suppose. I think so anyhow. Not sure if the effect would be enough to benefit on an aircraft system.
