Greenworks vs Toyota
Mass: 3.6 kg * 10 / 5 kg = 7x
Volume: 2 L * 10 / 10 L = 2x
Cost: ?
A battery designed for 3.5 kWh could certainly do better than using 10 of these smaller batteries, with their redundant systems. Also we should include the balance of plant for the hydrogen system since this cartridge is apparently just a tank (?). Fuel cells have notoriously low power density, whereas the power density of these batteries is excellent. So the batteries could come out well ahead, depending on the power requirements.
