fresh water available to wash and clean any contact with battery acid.
Uses insulated tools and avoid placing metal objects near the batteries.
Explosive battery gasses may be present during charging. Be certain there
is sufficient ventilation to release the gasses.
Avoid direct sunlight for outdoor use.
Loose power connections and/or corroded wires may result in resistive
connections that melt wire insulation, burn surrounding materials, or even
cause fire. Ensure tight connections and use cable clamps to secure cables
and prevent them from swaying in mobile applications.
Use with Gel, Sealed or Flooded batteries only.

controller to allow for cooling. If mounted in an
enclosure, ventilation is highly recommended.
