Re: Disposing of old lithium batteries

There was some company who recycles old EV cells and found that new cells made from recycled lithium (and the other stuff) outperformed "virgin" material made cells

Re: Tesla model x motors

In the description of the video they mention that software needs to be changed before their control would work and it can't be done remotely. So unless someone in Australia does the hard work as well, these front motors are basically useless (for now anyway). I guess the rear motor could be used wit...

Re: Brendon_m Moke

I've managed to finish up one of my packs and squeezed it into place. I'm thinking I should call this build "project snug" because there isn't a lot of clearance... anywhere. I had to lift the back end in half way, then the front and slide it forward and then the back the rest of the way. All while ...

Re: Hyundai Sales Tactics

Like putting an electric car in the oven to dry the paint. Im sure the batteries would love that. There are basic training courses for panel beaters to take so they can know how to safely work on EVs (how to isolate etc). Really anyone in an automotive trade should go on one before touching an EV an...

I'd say find an aftermarket replacement to the gearbox because using it is a pain, on the other hand I never found a reasonable cost alternative.

Re: Nissan Australia Leaf 1.0 battery replacement

BTW: I'm not sure if the US price is change-over though. I'd guess so. Nissan seems to have a strong desire to keep their packs out of the hands of us lowly commoners. I have heard of deals with 2nd life companies that buy the packs for home storage so there are probably contacts that force Nissan ...

The aluminum doesn't care if its at 25Deg or 300Deg.
True, but to heat aluminium to 300 degrees takes energy, and that energy is coming from the pack.
Although my experience of aluminium is you look at it with an angle grinder in your hand and it instantly jumps to 1000000°c

Yeah, I was a bit disappointed in the lack of intricate details but its not an in depth channel, more just a catalogue of cool/funny things. I was expecting more from the other contributors maybe they'll release their own videos with more nitty gritty on the build down the line. But that being said,...

Re: Battery interconnect sizing

A lot of the cells are in parallel so each cell only sees a small portion of the current. Each of your cells will see 1/2 the total current but from 1 pair of cells to next will be the whole kabootle Got it, thanks for clarifying! Just to clarify further it's not exactly half because you have diffe...

18A is the DC output at 140.4v DC. The AC input current on 240VAC is 20A.
Probably mistaking 240v for 110v.

Aluminum has 61 percent of the conductivity of copper
2/3 vs 61%.

Re: Battery interconnect sizing

Is the plan to have a square on the bottom that's 2 holes x2 holes and strips that bend up and down across the top that are 4x1?
Or maybe 4x1 strips along the bottom with 2x1s on top joining 2 10ah cells and separate one for 15ah cells?

After, soft seal would get in the way or making good contact.
For full disclosure, I have just finished making up my bus bars and due to the way my pack will be and I'm going to double stack the bars I had to flatten 52x 300mm bars and drill 312 holes. I don't wish that on anyone.

Re: Battery interconnect sizing

Copper doesn't need to be tinned, that just helps with stopping corrosion.
Im just going to use copper pipe from bunnings, squashed flat and drilled. I'll be using dielectric grease and soft seal to stop corrosion
