you can see by the name of each jpg that they both refer to a 48v20ah battery.
Sorry Gary, but unfortunately they don't.
The file name used for the 36V 15Ah duct tape battery was originally "LiFePO4 Pack.jpg" but when uploading the file to the web, the process of uploading files uses
FTP, which does not like empty spaces and replaces them with "%20" instead.
The file name should really appear as "LiFePO4%20Pack.jpg", but for some reason the "%" symbol does not appear in the attachment description.
Well at least now you know the reason for the confusion, but I somehow suspect that you wish you didn't!
