Brand new opened box.
Turns out this won't run on a 48V battery. I thought the settings were programmable, aside from their presets, and they are but they do not go to a high enough absorption voltage. I goofed. I need to buy a different charge controller.
Going to cost me $50 to ship it back through EBAY. Probably cheaper for me to mail it to you, if you want this controller.
Here's the link where I bought it, paid 323 for it two days ago.

I hooked it up to my batteries just to set up the Bluetooth to my phone. About an hour ago. that's how I realized the settings were not high enough.
Pictures in the next post.
