Where?
#1
Hi everyone. very new here.

I've checked the FAQs and all of the sticky'd posts, but cannot find the most basic. You all speak of these readily available cells, but I am in rural QLD and know of nowhere to get hold of any used batteries.

I've been checking out purchasing either new 18650's or lifepo4's since i need about 5KwH's to replace my current Trojan 48V setup. The new and used lithium battery industry seems rife with scammers and just a lot of thieves, but I'm hoping that you guys can offer some suggestions (something that will not require selling my children)


Thanks
Dave

Hi and welcome in the forum!

I had newer such experience! In Switzerland it easy, you go to a E-Bike Shop, ask for old Batteries, take them home, open and test them and voila.
You could also go to Shops which sell Laptops and ask for old Batteries.

Thanks for the reply.

No such thing as an E-Bike shop in this place. The only computer shop of any size is about an hours drive away and he has a contract to dispose of all of his Lithium Ion batteries.

Hospitals or Medical facilities. They have to replace their battery packs ever 2-3 yrs or so.

Find yourself a written off BEV, you dont have to use those tiny, time consuming format cells.

Hi Sean.
I don't know where you are from, but here in rural Australia, my town has about 2000 people and the nearest larger town about an hour away has about 30,000 people. I have never even seen an electric vehicle. They're pretty much useless with the distances required in this state. Maybe in the  big smoke they may have some.

Thanks for the suggestion anyway.

Ive messaged the other guy on ebay. Ill see what comes from that.

I'd guess that even rural Australia has an effective transportation system for large items, and item not available locally.

Well, you say that, but actually that's not true at all. I'm not in a rural area at all but quite the opposite instead. It's a rather densely populated metropolitan area and there are no readily available cells here. Given all the time and money I'd have to invest to get cells I'd rather buy new cells. This has been discussed over and over again, for many people buying new cells is the way to go. Prices for new cells are falling constantly while prices for used cells have been and still are going up. This story of tons of cells available for free is a very rare occurrence for most people. And while you're at it you can get larger format cells which further reduce the effort of making a battery.

I know that this doesn't meet the expectations of some people being able to reclaim cells to do something for the environment. But what can you do, this is what happens when people and companies are trying to make a business out of this.

So, if you can't find free cells locally, don't despair, you're in good company. Just buy new ones.

Yep, there's a few other expectations that perhaps those of us aware of lifes realities might need to point out more often - perhaps including .....

Building energy storage devices isn't easy to do quickly, safely and reliably.

There are no exact recipes available specifically for your requirements here so dont expect to be spoon fed the ingredients.

If someone tells you that building something complex is easy then they are likely just ignorant of what's really required (if they do make such caims proof and evidence should accompany their claim)

If you value your time purchasing a ready built commercial product will likely help you achieve your goals far quicker.

Dont expect building any of the systems outlined on this site to be financially beneficial (even in the very long term)

I'm sure theres plenty more  Smile
