I was looking at getting the pack on this page (last pack at the bottom). It says it is a 5s2p pack good for 80A cont, 120A peak. I imagine they are made from the 4Ah 10C cells. If I look at the cell specs, it says they are rated for 5C continuous. That is only 40A for a 2p pack. Am I reading this wrong? If not, is that why the 5s2p pack is so cheap at $165?
