Cold Charging (LFP Only)
Under normal charger operation, if the battery temperature drops below 5°C/41°F while charging, the charger will
switch to 0.1C charging. If the temperature increases to 10°C/50°F, the charger will resume normal charging. If
the charger drops to 0°C/32°F, the charger will shut down, and it will restart 0.1C charging at 5°C/41°F. When the
charge cycle first starts up and immediately enters Cold Charger Off or 0.1C charging, the charger will lengthen the
charge cycle times to help ensure that the battery is warm enough to accept a charge current.
The 0.1C temperature setpoint and Cold Charger Off setpoint are adjustable with the optional LCD. The recovery
thresholds are always 5°C/41°F (Δ5°C/9°F) higher than the setpoint when the charge cycle starts above the 0.1C
temperature threshold. When the charger starts the charge cycle in 0.1C mode or Cold Charger Off mode, then the
recovery threshold between 0.1C charging and normal charging is 15°C/59°F (Δ15°C/27°F).
