Both Dogman and dnmun responded to your assertion that these were 'dumped' telling you they were genuine cells so the above is not true.
However, this doesn't help mickk.
There are plenty of quality batteries to choose from that are plug and play.
Ping and cell_man have proven reliability and good reputations on this forum for LiFePO4 of different quality. One is low C-rate, the other high C-rate. The All Cell batteries apparently don't have the cycle life of LiFePO4.
There is a Dow Kokam NMC thread which should last 15 years and at least 3,000 cycles but you would have to build the pack yourself.
Don't purchase anything too hastily. Read up and ask others what their experiences have been of certain batteries and vendors. Best of luck.
