Well. Fuck.
Been looking into battery options, and the general internet consensus being that even 8D batteries won't run this bitch, and if they do they won't live very long. It wouldn't even bother me to drag a cord, but where you gonna get a 36 volt 15kw power supply? CV power source from a mig welded mounted on the ROPS? It's too much cobbling for what it's worth. If it was free, or less than $1000 I might.
If it was in my town I'd work on it to prove the batteries can hold some kind of charge, but it's not, and I'm slowly learning that my time is worth more than nothing...
Called the guy back and reneged on my agreement, and I feel like shit about it.
Sceep's right, the thing is scrap.
