These are two of the battery checkers that I use most often. The small one, a CellLog 8S, fits easily into a pocket,
so I always have it on hand. The larger one, a MaxPro LCD- 6, stays in the charger case. Both show individual cell
voltages as well as the total battery voltage.
The Hardline Pro Solution 1500W Combo from ProgressiveRC is a high-powered charging rig, with lots of power
available for charging big batteries in parallel. This is the setup that I use regularly in the shop and at the field.
you need to, sticking with a 1C rate for routine
charging will help the batteries last longer.
Here’s the process that I go through every time
that I charge a battery of any size. Doing it the
same way every time as part of a routine helps
eliminate errors that might cause problems:
• Check the battery with a voltage meter to
make sure that it actually needs charging.
A battery checker that shows individual cell
voltages is best.
• Plug the power leads from the battery into the
• Plug the balance lead into the balancing port
• Confirm that the cell count shows up correctly
on the charger display.
• Set the charge current equal to the battery
capacity on the label for a 1C charge rate.
• Start the charge cycle.
• Verify that the voltage and current being
applied to the battery are appropriate.
• As the charge continues, monitor the process,
checking individual cell voltages. If something
doesn’t look right, stop charging and correct
the issue before continuing.
how Many watts Do you neeD?
To determine if a charger is suitable for your
application, you must perform this calculation
to determine the maximum amp rate the
charger can supply: Start by dividing the watts
of the charger by the voltage of the battery
pack. This will tell you the maximum amp rate
the charger can deliver (watts/voltage = amps).
For an example, we have a 6S LiPo battery
pack and a charger that delivers 100 watts
