Rossw What is the yellow battery for?
Answered already... The yellow and grey ones are identical specifications, just different cases. Not even sure why.
Just wondering why you have the batteries stacked on top of each other?
In one of the other pics I posted, shows the batteries stood on end, 2 banks deep (front/back) with terminals at the top.
Stacking them the "new" way makes them not protrude into the room quite so far, and prevents anything put on top of them (or falling onto them) from landing across terminals. Even uninsulated, I feel they're safer and more compact this way.
They look nice and do not take up unneeded room on the floor and should be easy to work on when needed.
Yes, I also like that it's much easier to just run along with a multimeter from time to time and measure the voltages.
I am going to build a power shed this summer and I like ithe idea of things off the floor.
Thats why I built that plinth. It's solid, and it brings the cells up to a nice, convenient work height. No bending to get cells in or out, or to check them etc.
As an idea I would try and find a small plastic cover for each bus bar connection.
I have covers. I hate them. They fall off when you want them to stay put. They stay on when you want them off. It makes running along a bank to check voltages a long, protracted, 3-pass exercise (remove, measure, replace).
I would be foolish enough to reach over them and use the terminels to rest something on and short everything. But that is me. Looks nice. Thirteen
With them mounted as they are, I tend not to come into contact with batteries at all. It's a low-traffic area, the only other two people that have access to the area know not to take anything metal in their - and that if they DO, contact with the batteries will KILL them.... and if the batteries don't, *I* will.
