Maast

I dunno yet, it's in the line to be tortured next. I've got a GFB277 on the tester now and at .5C I only get 6 cycles per day so it takes a looooOOOOOOOoong time (weeks and weeks) to do enough cycles to get enough data to extrapolate lifecycle. So far all I've done to the cell model the OP bought is initial capacity testing and charge voltage holding, which it passed.so the cells just perform well Maast ? how many cycles ? how many months / years ? any problems ?
For what was paid for them though I do have to wonder if its a B or a C cell. Or did I just get ripped off. The quickest test of a quality of a cell after capacity is how well it holds a charge after its been charged up to 3.65v per cell. It should drop quickly (hours) to roughly 3.5 but then hold that for at least a week before dropping below 3.5 or 3.45 at worst. Capacity and charge holding capability is the first test from the factory to differentiate an A from a B from a C cell.
I hope the OP tests the snot out of his and posts the results, I'm super curious and at that price point if they're decent cells I'll be upping the number of cells I'll be buying myself from them. I got mine from a completely different vendor.
