Note that one of the ports has 4 pins that match the 4 hole connector on the battery.
See important note below for proper connection.
******************* !!!! IMPORTANT !!!! *******************
When you first plug in the battery & charger - all three (3) LED lights should turn red. Even if you just took it off the charger. This is normal.
Once the battery is fully charged - all three (3) LED lights will turn green.
Your SwiftPaws will work best on a fully charged battery.
If any LED does not turn green, your battery won't be fully charged and should be replaced.
Each cell holds a 3.7v charge - if one cell is not working, this will decrease the total charge of your battery.
