Any other method can result in early plug degradation due to charging arc.
Using ANY Fast charger on your Onewheel WILL degrade your battery quicker. This is true for Future Motions fast charger as well. This charger does not degrade your battery any more or less than the Hyper Charger. To prolong the usable life of your battery, you should try to avoid using this charger as your main charger. This charger is best used when you are on the go and you should use your stock charger when charge time is not important.
