3.3 Controller battery

The C550c controller has a lithium-ion (Li-ion) rechargeable battery.
Li-ion batteries have excellent power to weight ratios and can offer very long lifetimes. Some simple
steps to prolong the life of your Li-ion battery are outlined below.
Battery care

Do not discharge the battery too much; do not charge the battery too much.
Try not to discharge below 10%, or charge above 90%. This will dramatically increase the number of
charge and discharge cycles that the battery can achieve.

Only charge your battery at temperatures of 10-40°C (50-104°F). See below for more details.

Keep the power socket clean and dry at all times. Keep the main connection panel closed when the
controller is not in use. See the image on
Temperature
Battery life is affected by the temperature while charging the battery. At lower temperatures (below 50°F
or 10°C), chargers will lower the charging rate to reduce battery degradation. CUES therefore
recommends that you only charge the battery at temperatures of 50-104°F (10-40°C).
