Is it okay to stack ring terminals on top of one another when placing them on the battery terminal?

I noticed some people saying they needed to buy separate battery terminals, I'm not sure if that's because their ring terminal won't fit, or because you're not supposed to stack.

Any help would be great

Thanks

I would say because they had no more room...It does not hurt to stack terminals as long as you can get the screws or whatever tight to hold them all...

Hey, I'm actually gonna have some time soon to do the Big 3.
I was wondering if anyone know a good place online to buy wire.
And what type of wire would be the best?

if it's be discussed in the past, sorry.

I like the Knu wire...a bit pricey but good shit.

i know

pos from alt to pos on battery
neg on battery to chassis

i am not sure on the third one. I have seen chassis to engine and neg battery to engine as well.
What one am I supposed to do or are they both the same?


So could I either do
Strut tower to engine
or
Neg terminal to engine?

Instead of trying to remember what 3 you need to do it's more helpful to know exactly why you're doing each one.

1. Alt pos to battery pos -- the only positive run for the big 3 and is necessary to supply current to the rest of your system.
2. Vehicle chassis to battery neg -- your vehicle's chassis/frame needs to be grounded as that's what multiple electrical components both factory and aftermarket use.
3. Alt casing/Engine block to battery neg -- in order for your alternator to charge it needs a grounding point. The casing on the alt is used as a ground. Most people will attach a wire to the engine block because the alt is bolted onto the engine block. For minimum resistance, find a bolt that is NOT the alternator positive terminal, and attach it there.

Just adding it should be fine. I hope you're either getting a shit load of batteries or a HO alt for that much power
