Did you follow a guide for this? Seems hard to find info online about doing this with that model and I would really like to

Nope, just looked at the UPS, found it's 24V battery pack of 12V x 2 serialized, found the UPS is using AWG 10 wire. Ran the calculation for maximum current (900W / 24V = 37.5A). Got appropriate connectors for 10 AWG wire and 37.5A current, got batteries, got caddies, got voltmeters, connectors crimpers and just assembled everything together.
