I feel like a good like to like comparison would be the density of battery + motors compared to the density of fuel tank, engine and drive train.

Even more like to like would be to compare the battery with a fuel tank + a turbo-generator.

For any kind of battery, there will be a power threshold over which a fuel tank + a turbo-generator will be smaller and lighter.

So a useful comparison would determine those power thresholds.
