Bests & Worsts Reviews from Amazon

I've had this battery in operation for only a week, but as I've put it through its paces it has more than lived up to my hopes. After my purchase, I received an invitation from Chins, the manufacturer, through Amazon for any questions I might have. I've had a few casual operational questions which I submitted through Amazon and the company has come back overnight with thorough answers. They obviously are very customer driven. I wanted 200 ah of power for my home built RV and purchased this unit instead of two 100 ah units because of the cost savings and, importantly for me, the avoidance of having to deal with connecting two units together. The product has rope handles on each side, M8 bolts for connections on the top, and a solid appearance. It was a cinch to install--even at close to 50 lbs. Its worth noting that the cost savings are even more substantial if one needs 300 ah of power and can fit Chins' 300 ah unit in your available space. The cost per ah is dramatically lower than anything else I've seen from other suppliers. They say their lower prices reflect the fact that they are the manufacturer and sell direct. So far, I can recommend their products without reservation.
