At first, the two Power Packs look the same. They are the same size and weight. The difference is that the PRO Power Pack uses more advanced battery cells, with a higher energy density. This means you get 40% extra range. Also, the PRO Power Pack comes with a useful inbuilt light.
Based on using the Swytch Kit on Medium power, and adding your own pedalling power too, the ECO kit gets 35km average range and the PRO kits gets 50km average range.
The amount of range varies based on a number of external factors. This article explains how much range you can expect under different riding conditions.
Both Swytch batteries can be re-charged at least 1,000 times before you notice a drop in performance or range. This means it should easily last you 3 years before needing to be replaced.
See below for more technical details about the different Power Packs.
ECO battery capacity: 180W (36V 5Ah)
PRO battery capacity: 250W (36V 7Ah)
