XUBA batteries arrived

[joeExotic]

XUBA 120ah batteries arrived today. Took about two months to arrive. There's a button to push and it shows 13.3V. I kind of want to open them and look inside but not sure how to do that. The packaging was heavily padded. No nuts and bolts in the box can anyone recommend some good ones maybe on Amazon. They threw in 3 pairs of cables.

I sure would be interested in seeing some capacity test on those.

It is ok to wire these LiFePO4 Batteries in parallel?

 

[ArthurEld]

I think it is ok to connect the batteries parallel.
Check the box carefully for nuts and bolts.

If you don't find them buy stainless from ACE or some other home improvement store.

 

[joeExotic]

No nuts and bolts only 3 batteries and 3 pairs of cables. What size nuts and bolts?

No nuts and bolts only 3 batteries and 3 pairs of cables. What size nuts and bolts?

They are probably M6 or M8. Buy both and return the ones that don't work.
It is strongest to use headless screws and nuts.
But if your terminals have deep threads, screws work too.

Maybe read the book of words that came with them

 

[joeExotic]

No book just 3 batteries and 3 pairs of wires

 

[Bob B]

Generally wiring in parallel is not going to be a problem .... wiring in series is sometimes a problem because of the BMS used.

Contact XUBA and as them the size and that you also need to know the depth of the hole.

 

[joeExotic]

Ok I'll send them a message

 

[joeExotic]

Hole: M8

 

[joeExotic]

Is zinc plated ok?

 

[ArthurEld]

Is zinc plated ok?

Probably. Use antioxidant like Noalox

 

[joeExotic]

These are the right size, but nobody had stainless steel so I'm going to call a bunch of hardware stores to find them now.

 

[ArthurEld]

Stainless is better. ACE is good. Home Depot and Lowes probably have them too.

 

[joeExotic]

Is it a good idea to put a split washer on the bottom then the wire then another regular washer then the hex bolt?

 

[ArthurEld]

It is not good to put a washer under the connector.
The copper lug has to go against the terminal.

 

[joeExotic]

so first the wire then regular washer then the hex bolt?

 

[joeExotic]

So I drew a diagram of what my set up is going to be. Should I upgrade the fuse to 40A? what else should I do?
