Been messing with this bike some more. I ended up swapping it over to another frame because I absolutely couldn't stand that one it came with. Also switched over to narrower rims so I could use tires that weren't stupid wide. Next up, I'm going to replace the batteries in one of the packs and see how it does from there. The ones it came with were toast. Won't be hard at all though. It's just some huge sealed lead acids inside a plastic case.
