    For those who don't have the chance of having hot weather all year long to ride your bike....You need to store your bike for the winter. Here are 3 simple tips:[/COLOR]
    • Don't store the pack fully charged!!! Store your pack at around 40-50% charge. What is 40-50% charge on a 36V/48V/52V....? Well it's about 3.8V per cell so multiply this by the amount of cells you have on your pack (ex: 52V = 14s pack, 14x3.8V= 53.2V /////// and 48V = 13Sx3.8V= 49V//// and 36V is about 38V ). To test the voltage, wait an hour after use (or charge) before measuring with a proper DMM (digital multi meter)
    • Leave it in a dry place and unplugged from the bike and charger of course.
    • Keep the temperature above freezing, we recommend 40 degrees F (4 deg Celsius) but if your garage is heated you can go up to 58 degree F (15 deg Celsius)
    • VERY important: Unplug your battery from the controller and the charger even if not plugged to the wall outlet.


    I would even go so far as to encourage anyone with an ebike to put their battery onto a smart-charger once a month to a 50% charge to ensure it doesn't get low.
    When using the pack again, you will need to put it through the same sort of break-in you would do on a new pack: several cycles where you charge it to 100% so it can do balancing.
