Understanding the Cellpro 10XP Charger
Auto Charging vs. Manual Current Settings
When balance charging Li batteries, you can set the Cellpro 10XP Charger’s charge rate to one of three
AUTO modes—1.0C, 2.0C or 3.0C—as appropriate for the pack(s) being charged. When one of these
rates is selected, the charger determines the pack’s capacity (over time) and automatically sets the
correct output current using FMA’s advanced Fuel Gauging technology. The accuracy of AUTO
charging depends on how well your battery’s charge curve matches up with the fuel table being used by
the CP10XP. Six different fuel tables are available to support different Li battery chemistries and may
be assigned to individual presets using the Charge Control software. Factory presets for LiPo batteries
are set up for a generic, 15C battery profile. AUTO charging using the default presets may or may not
be accurate for your batteries. The advantage to using AUTO charging is that you do not need to think
about or even know the true capacity of your batteries. You can charge different capacity batteries at
different times without having to adjust the charge rate setting and the charge will automatically adjust
to choose the appropriate charge rate. You just tell the CP10XP how fast you want to charge, and it
does the work for you. For safety reasons, AUTO charging current is capped at 6A, regardless of the
size of the pack being charged. You can also manually set charge current to any value between 0.1A
and 15A in 0.1A increments. Finally, you can select Storage Charge mode which automatically charges
or discharges to the appropriate per-cell storage voltage for LiPo or A123 batteries.

Continuous Input (Watts) Continuous Output (Watts)
When one pack is connected to the charger, the pack is initially charged at the selected charge rate (or
the maximum charge rate possible). Using Ohm’s law, the maximum charge rate (Amps) is derived
from the maximum power (Watts) the charger can produce without overheating.
Maximum output power will normally reach approximately 605W when charging a 10s LiPo battery
using a 30V DC input power source, and assuming the input source can deliver a maximum of 720W of
