So what should I be paying for? Weight? $/lb value? $/Ah value? I am hoping at least for directed opinion.
Has anyone ever bought one of these? Are these manufacturers all full of beans because they are not Deka, Gates,Enersys, Hawker, or Concorde? I thought they all come from just a few source factories? Is there a reason not to buy a lower weight one for less $ and what appears to be a better value point? It is certain that none of these is a better choice than the others? They are all equal? Seems like the pertinent metric is $/Ah, unless you have a particular need for more Ah, then the "lesser" cells are a more valuable purchase.
