In Safety Charging Mode, the charger detects that at least one cell is seriously out of bal-
ance, and automatically lowers charge current to 0.5A.

attempts at charging, the pack is damaged. Treat damaged packs with caution. Do not
charge them on a ammable surface, and do not charge them unattended.
In Cold Weather Balancing Mode, charging automatically stops at 4.10V/cell when tem-
perature is below 55°F to prevent cell damage.
WARNING
Once the charger starts charging, NEVER connect additional packs or make any changes to
the charger’s external connections—including connecting or disconnecting discharge wires or
node connectors. When charging begins, the charger can no longer check for possible wiring
problems. Changes to the external wiring during charging will probably damage the charger
and/or packs, and is not covered by the warranty.
If the charger detects a problem, it will stop charging and display a safety code. If this happens:
1. Press the Mode button to reset the charger.
2. Reconnect the battery properly.
3. Press the Start/Stop button to continue charging.
