everything came well packed with no damages

So far So Good.

I'm using it as a 2nd battery in the trunk for my audio system and it's keeping the voltage steady/constant at or just below 14 volts.

Killer product

This is a great product and solved my voltage drop issues. Big Jeff's shipped very fast and had great customer service. They will definitely get my business in the future
