I picked up a used Emerson Liebert Vertiv GXT4 Double-Conversion UPS a little while back to better handle the dirty power coming from my portable generator, while feeding my server cabinet at the house. The internal batteries work fine, but I wanted to wire in some additional batteries for extra runtime before the generator would actually be needed. Unfortunately, it seems the external battery pack cable is exceedingly hard to find.<\/p>\n\n\n\n
As my UPS is a 48V battery pack model, I believe the right cable for mine would be model number GXT3CABLE48V1, unfortunately, that proved to be effectively impossible to reasonably source. I did find some GXT3CABLE144V1 model cables that in the pictures looked essentially identical, so I took a gamble and ordered one.<\/p>\n\n\n\n
I’ve found that the cables are effectively the same, but the plugs are keyed differently. So, all I needed to do was shave off the keying on the cable, and it worked fine in my UPS. Below is a photo of the shaved version above, and the stock version below. Hopefully someone else finds that helpful as well.<\/p>\n\n\n
