3D printer

Anyone here got/use one?

 

I'd like Lithium batteries in my Motorhome, but at nearly £800 a pop I'm giving them a swerve. I can buy the cells a hell of a lot cheaper but would need a 'carrier' to store the cells in. Anyone know about printers?

Yes, not so many of them are design for traveling though?

 

I was thinking something more like a milk crate.

Don’t know. We’ve reached the limit of my knowledge. It does happen.

Can’t you just buy one of those and put it in a milk crate?

I own few 3d printers and they are a nice hobby but it's not just buying one and making what ever you want to make. Usually I design and try different settings for few hours and the print itself takes 20mins. If those brackets are only thing you need I think it's better just buy those.

Wouldn't you need to spot weld the cells into banks and then join the banks in series? Then you need a battery management system to control charge and discharge

Yes, all of the above. I've been reading about balancing, and I'm out of my depth at the moment. More reading needed but I'm sure it's doable.

Each unit holds 20 - 18650 cells. Once assembled, these cell holders are very difficult to take apart. Trying to do so, you will...

 

 

and cut them to size, the BMS then has to link into each bank and see the voltage so it can equalise the banks.

 

It#s all new to me but I am looking at changing an obsolete electric bike with a brushed motor over to Lithimm phosphate  and a different controller.

 

Other thought is to use some 2.5Ah batteries from power tools.

I never knew such a thing existed, that's the sort of thing I was thinking of.
