Does anyone know the technicalities of using a coiled spring connected to an electrical motor as a "battery"?

I guess it would be larger, but would it be able to do the job, if for some reason clunkiness is not a problem?

Just posted a battery status logger for Eco-worthy Bluetooth LiFePo4 batteries. There was a good sale on these during the holiday. This program, for a Raspberry Pi or similar, will connect to the battery and log volts, amps, watts, SOC, and cell voltages to a CSV file. Can even trigger events on high or low SOC. #solar #battery #batteryhacks

Long shot, but does anyone know if the Lithium Ion battery inside a #PS4 #Dualshock4 (I know there are two different connectors) has charge protection circuit built-in or does the controller handle all that.
I am toying (sic) with the idea of fitting a non standard replacement battery.
I may bodge a couple of throw away vape cells together.
