MEP-831A - battery tray & tie down

[uniquify]

I recently picked up an 831 that is missing the battery and some related items. I've read about guys using a pair of commonly available motorcycle batteries in series instead of the stock 24v battery. I'm curious if anyone has had luck sourcing or improvising the battery tray and tie down bracket.

Ended up finding a pair of 20HL AGM batteries on sale. The local Advance Auto Parts store had a universal battery hold down that fit over the pair of batteries. It came with a small bracket that worked for the left side, and it had plenty of holes on the right side to facilitate a pair of J-bolts. The batteries aren't going anywhere.
