charging
Before charging your batteries, it is critical that you determine
the maximum allowable charge rate for your batteries. The X1 Pro
is capable of charging at high rates that may not be suitable or
safe for your particular batteries. For example, Lithium cells are
typically safe to charge at 1C, or the total mAh÷1000. A 1200mAh
battery would have a 1C charge rate of 1.2 amps. A 4200mAh bat-
tery would have a 1C charge rate of 4.2 amps. Some manufactur-
ers are offering Lithium cells that can be charged at greater than
1C but this should ALWAYS be verified before charging a Lithium
battery at rates higher than 1C. Voltage is just as critical as the
charging amperage rate and this is determined by the number of
cells in series, or “S”. For example, a 3S LiPo is rated at 11.1 volts (“S”
multiplied by a single LiPo cell with a nominal voltage of 3.7 volts
DC. 3 cells x 3.7 volts each equals 11.1 volts DC).
Connect the battery’s main leads to the charger output: red is
positive and black is negative. Keep in mind that the gauge or
thickness of your charging leads from the X1 Pro to your battery
must be of an acceptable current rating to handle the applied
