[RE-wrenches] Battery interconnect cable length

[bob ellison]

Benn,

It's just one of the necessary evils we have to put up with.

Size it at least as large as the main leads, (2/0 or 4/0?) 

Sometimes we have to go around supports and vent fans and such in the boxes.

I like getting the cells and welding the straps onto them or bolting them
directly together, when possible. 

 

I like this, mind if I "liberate" it?

Subject: [RE-wrenches] Battery interconnect cable length

 

Since batteries seem to be a hot topic lately, I've got a question...

...in a single 48V string, (24 x 2V) if each interconnect cable  is
14"-4/0awg and one cable in the middle of the string must be longer (btwn
20"-24" total length)...

How detrimental will that be to the overall efficiency?

 

Should it be OK or should the awg size for the longer cable be larger?

What other factors should I consider?

 

Thanks,

benn
