I would pass on the 'Battery Minder EZ Connector.
Those 12v SAE connectors, in my experience heat up greatly and wear out quickly. I used both 10AWG and 18AWG SAE connectors in the past, and had many outright fail and others heat up to the stinky plastic arean at just 20 amps of current. I have removed ALL of them in favor of anderson powerpoles
I'd use anderson 45 amp powerpoles with 10AWG. These are much more reliable and have much less resistance.
Mine regularly pass 40 amps without issue or excessive heating.
The 45's are not so easy to crimp without their special crimper. the 30 amp ones can be crimped with a simple dimple crimper but can only handle 12awg.
