Cold Weather and Outdoor Usage
Cold temperatures (below freezing) can impact the Vulcan’s battery capacity. If Vulcan will be
operated in sub-zero conditions, without its heating option, we recommend maintaining a
constant load to keep current flowing through the battery and BMS system to generate internal
heat from the electrochemical reaction within the battery cells. The BMS will shutdown battery
charging if the battery core temperature drops below 0ºC/32ºF.
When using the Vulcan outside, place it under cover and keep moisture from coming in direct
contact with the unit. Do not place the unit in standing water. Ensure adequate clearance of at
least 1 ft front and rear to guarantee proper ventilation to cool the unit. Following these
recommendations will help to maintain optimal unit life, keep the battery at its highest capacity,
and ensure the longest battery cycle and calendar life.
CAUTION
When operating in temperatures above 32ºC/90ºF, ensure there is adequate ventilation to allow for
airflow into and exhaust air out of the unit. Do not use it in a confined space that is void of ventilation
to the outside air. Refer to section Installation on page 34.
