These batteries have good voltage but they have some swelling. Only one left at the moment. Great if you need a replacement cell.

This is a great overall cell for many applications.

This calculation also takes into consideration the maximum continuous amp ratings of the cells.

M6 bolts are not included but the Headway bolts fit these if you need some we have them for a few cents per bolt. Often times customers use thicker busbars and order their own bolts at the length they need. The headway bolts would work if you are using up to 1/4" thick busbars.
