Mini akkumulátor-kiegészítő készlet – 65 A

The Mini Add-A-Battery Blue Sea 65A kit is designed to simplify charge management in dual-battery systems. It allows charging two batteries from a single alternator (up to 65A) while ensuring their isolation to prevent one battery from discharging the other.

The Mini Add-A-Battery 65A kit includes two main components:

An automatic charging relay (ACR) m-Series 7601. A Dual Circuit Plus™ battery switch m-Series 6011.

This kit is designed for alternators with a capacity up to 65 amperes.

The automatic charge relay (ACR) m-Series 7601 automatically combines batteries when a load is applied (e.g., by the alternator) and isolates them when batteries discharge or during engine start. This function protects the starter battery from accidental discharge.

Yes, both components in the kit are ignition-protected. The m-Series 7601 automatic charge relay (ACR) meets the external ignition protection requirements of ISO 8846 and SAE J1171. The m-Series 6011 Dual Circuit Plus™ battery switch is also compliant with UL1500 and SAE J1171.

The automatic charge relay (ACR) m-Series 7601 is rated IP67, meaning it is protected against temporary immersion up to 1 meter for 30 minutes. The Dual Circuit Plus™ m-Series 6011 battery switch is rated IP66, protecting it against powerful water jets.

The "COMBINE BATTERIES" function of the Dual Circuit Plus™ m-Series 6011 battery switch allows you to parallel the two battery banks in case of a weak battery, providing an emergency start option.

For a 12V system, the automatic charging relay (ACR) combines batteries when voltage reaches 13.6V for 30 seconds or 13.0V for 2 minutes.

For a 12V system, the automatic charging relay (ACR) isolates the batteries when the voltage drops to 12.35V for 10 seconds or 12.75V for 30 seconds.

The automatic charge relay (ACR) includes overvoltage protection at 16.0V DC. For undervoltage, it has a lockout at 9.5V DC for 12V systems and a reset at 10.0V DC for 12V systems.

Yes, the automatic charge relay (ACR) m-Series 7601 is compatible with 12V and 24V DC systems. The Dual Circuit Plus™ m-Series 6011 battery switch has a maximum operating voltage of 32 Volts, making it also compatible with both systems.

For the automatic charge relay (ACR) 7601, the minimum recommended cable sizes to comply with nominal currents are:

For ≤30A: #10 AWG (6 mm²)
For ≤50A: #8 AWG (10 mm²)
For ≤65A: #6 AWG (16 mm²)
Larger cable cross-sections may be required to minimize voltage drop over long distances.

For the Dual Circuit Plus™ 6011 battery switch, the recommended cable size to meet nominal currents is 4/0 AWG (120mm²) per terminal.

To prevent corrosion of wires and connection terminals, it is recommended to install the ACR in a dry and protected location if possible. Avoid locations directly above battery banks.

The Dual Circuit Plus™ battery isolator must be installed in an easily accessible location close to the batteries.

Before starting the installation, it is imperative to disconnect all battery connections for safety reasons.

Minimum connections for ACR operation are:

Connect the positive terminal of one battery bank to one of the 1/4"-20 terminals.Connect the positive terminal of the other battery bank to the other 1/4"-20 terminal.These two positive connections must be made through appropriately sized circuit protection.Connect the quick-connect terminal marked GND (ground) to the DC system ground using a 1 amp inline fuse.

To activate the start-isolation (SI) option, connect a wire from the quick-connect terminal marked SI to the terminal or wire running from the ignition switch to the starter solenoid. This connection must be made via an inline fuse rated 1 to 10 amps and must be positive only during engine cranking.

The recommended tightening torque for the 1/4"-20 (M6) terminals of the automatic charging relay (ACR) is 60 in-lbs (6.8 Nm).

The recommended tightening torque for the 3/8"-16 (M10) terminals on the Dual Circuit Plus™ battery switch is 120 in-lbs (13.56 Nm).
