I just bought QTY1 for $440 shipped... that's one heck of a deal. Ha, I now have batteries from six different lithium vehicles . This is a standard (i.e. non-LTO) lithium cell. Rest assured I will give a full technical review once they come in. Using QTY2 18-cell packs and QTY1 12-cell pack yields 201.6 full charge voltage, which is an excellent drop-in replacement for the OEM system... note you'll almost certainly want a BMS, unless you like living dangerously.
