Connecting your battery to your charger is pretty straight forward!
# 1 Plugs into any standard 110 volt household outlet
# 2 This connects the wall cord to the Charger block
# 3 After sliding the door open, the metal plug from the charger goes into the battery.
# 4 Once charged, the cord on the bicycle plugs into this port.
Note: While the plug from connection # 2 looks like it will fit into port # 4 on the battery, it is slightly different, and will not go in. Do NOT attempt to force this, as it would create a severe fire / explosion hazard!
