Abyss Battery User Manual

Description

This is a fully automatic DC-DC charger that charges both your starting battery and 36V Trolling Motor Battery from your outboard engine's alternator, a power supply system designed for RVs, campers, and Boats, etc.

DC-DC charging: refers to charging your Auxiliary battery through an alternator / generator and starting battery.

1. While underway, the alternator from your outboard can quickly charge the 36-Volt trolling motor battery through the full power of the Abyss Battery DC-DC charger.
2. The charger can charge the main battery according to the specified voltage and current by boosting or reducing the voltage to ensure that the main battery is in accordance with the standard operating requirements.

Features

1. Fully automatic charging: The controller can always be connected to the starting battery to continuously charge the battery. When charging energy stops, the battery will not discharge in reverse when you stop or are stationary on your boat.
2. Stable output voltage is 43.8V.
3. ACC control port can turn off the output voltage.
4. Intelligent chip with voltage wake-up function.
5. 100% full rated power.
6. 100% full stable output Current.
7. 100% burn-in-test.
8. IP67 waterproof Epoxy potting, Anti-vibration, Dust proof.
9. Cooling by free air convection.
10. Under voltage protection: Identifies the starting voltage of the car and wakes up the charger.
11. Overshoot protection.
12. Over temperature protection: the operating temperature range of the shell is -40~85℃.

Installation Steps

1. Turn off all power and load switches.
2. Connect the OUTPUT “+” to the positive pole of the load device or auxiliary battery. Connect the OUTPUT “-” to the negative pole of the load device or auxiliary battery.
3. Connect the INPUT “+” to the main battery or generator positive pole and the INPUT “-” to the main battery or generator negative pole.
4. Turn on the power and load switch, and the converter works normally.

Connection Diagram

A diagram shows the connections for the DC-DC charger. It illustrates the ACC, INPUT (+ and -), and OUTPUT (+ and -) terminals. Wires are shown connecting from a 'Generator' to the INPUT terminals and to a 'Main Battery' from the OUTPUT terminals. A label indicates 'Ignition or Switch' connected to the ACC terminal.

Notes on Connection

1. Wires: 16 square wires are used to connect the input, and 4 square wires at the output end.
2. If your wiring connection is more than 2 meters, a thicker gauge wire is recommended.
3. The Input Voltage should equal or more than 40A.
4. ACC: The charger starts to work only after the control voltage is applied to the control terminal, and the voltage range can be 3V~36V (Can directly connected to the 12V input terminal if No additional control is necessary.)
5. Make sure all polarities are correct before wiring; reverse connection will burn out the converter.
6. DO NOT connect input and output in reverse.
7. Make sure the battery capacity is large enough to provide enough power. If the input energy is insufficient, the voltage will automatically decrease.
8. Ensure that the installation environment is well ventilated to avoid over temperature protection and limit current output.
9. Cables need to be fitted with large current lugs and securely attached.
10. Please install the charger as close to the main battery as possible, and keep the surroundings clean, tidy and ventilated.

Output Current Curve

A graph illustrates the output current curve over time. It shows three phases: 'Bulk', 'Absorption', and a final stage where 'Voltage remains constant'. The graph plots Voltage (U/V) and Current (I/A) against time (t).
