If the battery technology (standardization and price, obviously performance is already here) were here, I'd absolutely consider an electric re-power for my 318 Satellite.
Our son has had a tesla model 3 for about 2 years and has (on my request) kept track of his electric bills, including a pre-tesla average.
He reports (with the optional 30A/240V charger) it costs less than $25 per month to operate.
That is real world savings including electric generating consumption.
The battery life cycle, disposal, and cost issue however, is also real.
