To be clear - this is 55lbs for 5kwh of power in a 22v nominal pack. You will need more than one to get to 20 miles of range in an aftermarket conversion, and you will still have to add 100+lbs of motor on top, in addition to cooling/wiring/electronics. I see this system coming in around 300lbs on the low side. Again - the battery is not the system, and this is still 100lbs of battery to get to 20m of range in an aftermarket conversion.
