Notes
This battery was constructed with four “A123 20 Ah” pouch cells in series. These cells were represented as genuine A123 but when received bore different markings than the verified A123s we have purchased in the past. They may have been genuine rejects or just plain fakes, either way they delivered 72% of their rated capacity. The genuine A123s often deliver more than rated capacity.
