Lithium terminals

[Busman]

One probably for T1.
Building a new battery for the solar system going in in a couple of weeks, 48v x 400 Ah Winstons

T1, did you ever find a way to clean the battery terminals before assembly. I have strapped them in the box already so difficult to run a file across the top, any other suggestions ?

Got to get this assembled before a total knee replacement early next week.

Cheers

Bill when I had them I just used 400 grit emery on the end of a finger on the terminal & similar on the straps. Don't take any off really...... more like polish them. Good wipe over with clean cloth & then a very fine smear of paste. The paste is really only to fill any minute scratches on either. I learnt years ago that too much paste on computer CPU's is a good way to fry them. I admit on CPU's it's about heat dissipation & not electrical conduction. All these big words..... got no idea what they mean!

Thanks Bruce, will give it a go.

All done ready for the solar system

Looks good!!
How far do you need to shift it to? Guess you have a fork lift handy though.
Bill I put a fuse on each sensor wire "just in case" & it did save me a few times.
I still have a fist full of 1A if you want? I used those block of 8 fuse blocks.

It is on heavy gate wheels Bruce, it will slide under the switchboard, 1800 x 600 whiuch will be on its side to take the three Victron Multiplus's.
I have the wires on the battery in VP fused, will get to these in time, had tp get it finished before knee op.

In the old PMG days in the battery room we used to buy a new untouched by human hands wire brush and brush the terminals to a clean finish to remove any oxidization and the same on the busbars or cables with a thin layer of paste.

Yehh ..... I remember that, those Brass Wire brushes were a treasured keeper.
The battery room was a thing of power unlimited with 2 banks of batteries that could melt a 5x1" busbar in a flash, saw it done, and the ensuing panic as the exchange went Offline.

I have used solid bar drilled to take bolts at the right places 25 x 3.2mm. I have always used this and had no problems and way cheaper than the flexible ones. I am wanting to get a top on the battery before someone drops something on there !!!!

Clear perspex. Can drill it & see the mouse nests thru it.
