Mounting the Batteries

I am going for a 60 volt system, 5 12 volt 22NF AGM batteries, model UB12550 specifically. Each weighs about 40 lbs, resulting in a 200lb pack. Oof.

I found a source in Louisianna via EBay that sells 2 at a time. I am starting out with 2 until its definitely all working. I also have a digital charger now via Target, thanks to my car battery dying when I was out of town for 2 weeks.

I went with plated L channel material (1.25 x 1.25 16 gauge) with predrilled holes, allowing me to go "erector set" to build a box in which to hang the batteries. I am concerned about the bolt heads getting in the way, I might need to get screws and/or rounded heads.

I predict I will be adding much cross strapping when the full 200lbs
of batteries is installed. I am also concerned about the battery terminals accidentally contacting the box frame.
