making custom battery terminals


Recommended Posts

I'm thinking of making my own battery terminals and was wondering what you guys suggest to use as far as the metal for them. Ill either drill a hole and slot to squeeze the terminal or I could just bolt it to the battery. I'm gonna make the terminals pretty simple at first. Figure 3/4" think by 2" wide and 3-4" long. and I'm making them to hold ring terminals. I was thinking copper at first but that would corrode pretty quickly. And I'm not sure steel would be good for flowing current. Any suggestions guys?

ya that makes sense. im wondering if i should thread the block or put a bolt thru with a nut on one end. i dont wanna strip out the block and aluminums kinda soft. depending on what i use to the bolts to hold the rings that is.

I've used quite a bit of copper and I've never had corrosion. The pieces under my hood have been untouched and abused with current for over a year and they are still pretty. My only issue with it is price.

Aluminum is not as soft as you think. There are quite a few guys on here who tap aluminum. I personally drill slotted holes without tapping and screw down to the batteries.

I've had great results with both. My max width I've used is 3/8". Anything bigger than that is almost a waste. I think 3/4" bussbars is overdoing it.

Need an install? Hit me up.
