Thanks woody for spotting them. I have emailed him a couple of times and he said they have been used once. Has anyone had any experience of these cells from this seller. I am very tempted to order a load to make up some packs. I can see a few chargers on the market for the A123 cells but based on experience can anyone recommend one? Tanglefoot is running on 2 X 750 Watt 36V motors so I am planning on using 2 packs of 10 cells. By using these cells it is the only way I am going to have any weight left over for amour.
