Microprocessor Controlled Lithium 12V/14V/16V Automatic Battery Chargers
The Li Charger series is a group of advanced battery chargers designed specifically for high performance 12V, 14V or
16V lithium ion batteries. These chargers combine the reliability of a High Frequency MOSFET rectified assembly with an
advanced microprocessor control board to create a battery charger that can rapidly and safely recharge 12V, 14V and 16V
lithium ion batteries in several sizes.
Voltage Monitoring
The battery’s terminal voltage is measured every five minutes by the on-board microprocessors and this information is
analyzed in addition to the elapsed time to dynamically control the battery charger for optimum charging performance.
Automatic Computer Analysis/Auto Shutdown
The microprocessors will analyze the battery when connected. If the battery’s voltage is below 4V the charger may not
recognize the battery is connected and will not begin charging. Likewise, if the battery will not come up to the correct voltage
in a ten-hour period the microprocessor control board will automatically shut the charger off.
UL Approved Battery Cables
Six feet of durable battery cables are provided that are resistant to cuts and abrasion. The copper plated battery clamps are
compact and custom designed easy connections. All clamp connections are soldered for maximum current flow.
Internal Cooling Fan
A cooling fan automatically operates during charging to keep the circuit and other internal components at a constant safe
temperature.
▪ Important Safety Instructions
The Li Charger series generates a low DC voltage and high DC current to the battery being charged. Operating the
charger incorrectly or misusing it may damage the charger or create hazardous conditions for the user.
WARNING: EXPLOSION HAZARD
• The Li Charger series is designed to charge 12V, 14V and 16V llithium ion batteries. Do not attempt to use with batteries
with voltages not matching the chargers specified voltage.
• Do not use this product where there are flammable fumes or gases.
• Do not use this product in an enclosure containing lead-acid batteries. These batteries vent explosive hydrogen gas, which
can be ignited by sparks from electrical connections.
• Never attempt to charge a frozen battery.
• Do not connect DC clamps to the carburetor, fuel lines, or sheet metal body parts.
• Do not leave unattended while charging.
