HOW TO Charge LiPo Batteries
to the charging port (keep in mind that a 100-watt charger with two
charging ports might only deliver 50 watts per port). Divide 100 watts by
22.2 volts ( 6 cells) and you get 4. 5 amps. This means that the charger can
supply a maximum of 4. 5 amps to a 22.2-volt 6S battery.
Of course, the charging amp rate would gradually reduce as the battery
voltage increases during the charge cycle. In this example, you could only
charge a 6S 4500mAh battery at a 1C charging rate. Any battery larger
than that would be charged at less than the 1C rate, which means it might
take a little longer depending on the discharge of your battery.
With today’s balancing-charger designs, charging a LiPo battery can be a
safe and stress-free process. Just remember to read the battery label and
keep in mind that a 1C rate is usually a safe bet.
Here is the i Charger 306B display showing individual cell voltages as the charge
progresses. When these get to 4.2 volts, the charge process is complete.
Here is the iCharger 306B display before the charge begins. It shows the charging
method in the top line and the selected charge current, battery voltage, and cell
count in the bottom.
Here is the iCharger 306B display after the charging process starts. There’s a lot of
information there, including charge current and pack voltage up top with accumulated charge in mAh and elapsed time at the bottom.
