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 page 29 .
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).
