Operation Guide
Thank You for purchasing another quality GSL Product. This Micro Controlled Booster Charger has been designed to
overcome the limitations of most auxiliary charging systems.
The NGBC1222 is a Next Generation full 3 stage 22Amp Charger which will operate from voltages as low as 11.5Volts up
to 15.5Volts whilst still providing optimal charge to a variety of lead acid and lithium battery chemistries. Feature rich unit
incorporates revolutionary new concepts in battery charging.
Featuring:
Optional:
• Automatic Start Assist - Using a solenoid (Sold Separately on NGBC1222-1) will automatically jumpstart from an axilliary battery.
• Constant Output Power Limiting - Giving you more charging current when auxilliary battery is low (Up to 25A output)
• Thermal Compensation - Via optional external LM series sensor. (For Lead Based Batteries Only)
• Automatic voltage drop compensation - calculates and overcomes voltage drop on long wire runs.
• Polymer Encapsulation - Weatherproof convection cooled aluminum construction.
• High Operating Temperatures - Safely work up to 70°C. Full power output to 45°C with gradual power degrading to 70°C

The remote LED indicator can be installed where it will provide a simple visual indication of the system status.
The LED anode (+) should be connected to the YELLOW wire and the cathode (-) to the vehicle chassis or the battery negative.
ON : Auxiliary battery charging
Flashing : Auxiliary battery charging at low voltage
Blinking : Automatic Start Assist operated. This is a latched alarm indicating that there is a serious issue with the main battery or
cabling. Please check your main battery for issues. Refer to Automatic Start Assist section for more information.
To reset from latched alarm: the ignition is required to be turned off and on.
OFF: Unit not working or not in operation.

Notes:
• Before installation the user shall determine the suitability of the product to ensure correct application.
• Check with your battery manufacturer for the suitablity of the charger for your installation.
• Where Lithium battery banks are invovled ensure your BMS system is compatible with our charger.
• A large spark can sometimes be generated during connection, due to the current required to charge the capacitors in the
charger.
• Do not short output when enabled and operational as this may cause damage to the unit.
The following connection sequence is to be followed: Ground (BLACK), Input (RED), Output (BROWN), Chemistry
(ORANGE) & Control (BLUE).
1. Disconnect the battery supply.
2. Choose a mounting position - Select a position with good ventilation where air can pass freely around the unit.
3. Avoid locations such as fuel lines or where external heat is produced e.g. exhaust system or where the batteries are
located.

Follow connections for ORANGE, BLUE & YELLOW as per Fig.1 or Fig.2 where
applicable.
Important: If Optional Start Assist Pack is not purchased with kit then
make sure that the solenoid is capable of at least 100A.
Cabling used in the start assist bypass (ASSIST Wire and RED) will
need to be suitable for high current stresses for starting the vehicle.
This optional extra enables the automatic use of the energy stored in the auxiliary battery to start a vehicle with a faulty or
discharged main battery.
When using this option a high current solenoid is activated for approx. 30 seconds following an ignition attempt where the main
battery drops below 7V.
, and no auxiliary
battery charge will take place, to insure the main battery is replenished as soon as possible, until the next ignition attempt.
Temperature Compensation :
Temperature compensation of the battery charging voltage extends the battery life and improves the charging process.
Fixed charging voltage can result in either undercharging the battery at low temperatures or overcharging it at high temperatures.
of the battery operating temperature.
The NGBC1222 applies a small negative coefficent to the programmed voltage (Approx. -5mV/°C) to compensate for the variation
Attach supplied Thermal sensor to the smaller Black and Red wires (Not the Main and Auxiliary wires) and mount the sensor near
the battery to measure ambient temperatures at the charging/auxilary battery
.
(This feature is for lead based chemistries only.)
