Battery connectors

May 02, 2021 by Lukasz Kumanowski

My cry for help regarding proper adapters for connecting battery boxes with electrical cables resulted in a storm of ideas from my Dear Readers. Thank you!

Albert sent me a very neat solution which gave me idea of making my own adapters. I turned them in aluminium - maybe not the best material for this but that I had at hand. Thick cylinders match “+” & “ -” openings in aku clamps. M12 thread matches holes in battery box cables. Wide collar should maximise contact area.
The only thing which does not work is that I made the wrong thread! I cut is as M12x1 while common nuts are M12x1,75!

I’ll try buying matching fine-threaded nuts in Norrtälje. Anders gave me a tip that there is a shop in Görla with such uncommon stuff.
I could make them myself, too.
Otherwise I’ll re-thread them into proper thread or turn them into smaller, M10.

POSTSCRIPTUM

I finally decided to re-cut threads on these bolts into standard, coarse M12. There was enough meat left in M12x1 to yield healthy, proper threads.

I took Jim’s and Anders’ advice and visited Bremers in Görla. Well worth it!

Equipped with four A4-grade steel wing nuts I’m now ready to instal it on Meritaten. Thank you guys!
