Batteries look great and work well, unfortunately I only recieved 3 of the 4 Batteries I ordered. The company replied back right away that the shipment got separated during transit and assured it was still in route. The missing battery was delivered a few days later.

Thought this would be a great upgrade to my used RV. SO DISAPPOINTED. Charged both batteries with a new 55amp charger. At the end of 12 hours, they were giving two different voltages. Went to put in the coach and only one battery would fit. Started there. Swapped in new charger. Added a kill switch to isolate it from alternator. It's not charging and dies. What a waste of my money.
