INPUT POWER

AC Input: For indoor use, this charger includes a built-in switching AC power supply that delivers power by connecting 
the AC power cord to a common 110V AC outlet.

DC Input: This charger can be powered by a portable 12V DC power source for use at the track. On the left side of the 
charger, connect the DC power cord’s alligator clips directly to the output terminals on the 12V DC power source. Always 
match polarities (red lead to red “+” terminal, black lead to black “-” terminal). To utilize the charger’s 

absolute maximum

 

power capabilities the DC power source must be capable of delivering at least 7.5 amps while maintaining 12 volts DC. 

WARNING! Never accidentally short together the positive (+) and negative (-) input connections when 
connected to 12V DC power. Failure to do so could result in permanent damage to the power source and 
the charger.

The charger is rated for a maximum output power of 50 watts. Depending on certain conditions (if charge current is set 
to maximum, the maximum number of cells are connected to the output, and input voltage is low), the actual current 
delivered to the battery might be slightly less than the setting. This is normal.

The charger will be on at all times when connected to input power. Disconnect the charger from input power when not 
in use.
