45a controller 60a battery

What is the average life expectancy of a Chinese made battery like this?

I was wondering why and how the controllers on scooters are so small in comparison to a ebike controller if a similar watt. My 500w ebike controller is 50%+ bigger then my 1200w controller. Just curious
