Description
Blue Sea 7601 Mini ACR | Boat Supply Store
For boaters operating with dual battery configurations and alternators up to 65 Amps, this device automatically manages charging between banks, preventing parasitic drain and ensuring both batteries remain charged. It intelligently senses charging voltage, combining banks at 13.0V DC after 30 seconds and separating them at 12.75V DC after 30 seconds. The unit features a compact design for versatile mounting and offers robust protection with an under-voltage lockout at 9.5V DC.
Key Features
- Automates dual battery charging, eliminating manual switching.

Common Concerns Answered
Will the terminal studs accommodate thick cable lugs?
While the 5/8" stud length is standard for many marine applications, users with exceptionally thick cable lugs may find them somewhat short. Ensuring proper crimping and terminal selection is key.
I'm confused about the specific voltage thresholds. Can you clarify?
The relay automatically combines batteries when the charging voltage reaches 13.0V DC and sustains for 30 seconds, and it separates them when the voltage drops to 12.75V DC and sustains for 30 seconds, ensuring efficient charging cycles.
What if my alternator output is higher than 65 Amps?
For vessels with alternators exceeding 65 Amps or requiring faster charging of larger battery banks, a higher-rated ACR such as the Blue Sea Systems 7610 (120 Amp) may be a more suitable option to avoid potential strain on the relay.
Frequently Asked Questions
How does the Blue Sea 7601 DC Mini ACR automatically manage battery charging?
The ACR automatically senses the voltage from the alternator. When the voltage on one battery reaches a specific combining threshold (13.0V DC after 30 seconds), it connects the two battery banks together for charging. When the voltage drops below a separating threshold (12.75V DC after 30 seconds), it disconnects them to prevent discharging the primary battery.
What is the continuous amperage rating of the Blue Sea 7601 DC Mini ACR?
The Blue Sea 7601 DC Mini ACR has a continuous amperage rating of 65 Amps, suitable for alternators up to this capacity.
Can the Blue Sea 7601 DC Mini ACR be mounted on a panel?
Yes, the unit features a compact case design that allows for both surface mounting and panel mounting.
What is the voltage lockout for the Blue Sea 7601 DC Mini ACR?
The Blue Sea 7601 DC Mini ACR features an under-voltage lockout at 9.5V DC to protect batteries from over-discharge.
What is the maximum cable size supported by the Blue Sea 7601 DC Mini ACR?
The unit supports a maximum cable size of 1/0 AWG, ensuring robust electrical connections for its rated amperage.
