Hi Everyone

Hi Everyone!

I have been lurking here a while, but decided it is time for me to start partiicipating.

I have learned a lot from Pete's videos as well as AverageJoe and Nerdville.  Thank you very much to each of you for the fantastic videos!

I have just started my own 18650 adventure with 2 battery packs opened.
One pack had 2 cells and one had 8.

I am planning on starting out small with a few USB powerbanks.

The 2 cells were charged before the pack was dismantled, and they seem to be holding charge, but the 8 cells are close to zero volts.

So far I have bought a few 18650 cell holders, some TP4056 modules and some zb2l3 for capacity testing and a few empty usb powerbanks (2,4 and 6 cell) for 18650 cells.

I am not sure what next after the USB power banks.  Maybe an ebike conversion.

I like the idea of a decent size powerwall or possibly even an EV car, but have to see how things go.

My young daughter is very excited about the idea of participating in recycling and that is what made me take the step from thinking "That is an interesting idea" to "I am going to give it a go".

She got hold of the multimeter today and checked the voltages of each of the cells.

Thanks to those who have put this community together and everyone who participates here.

James.

Welcome!

Perhaps convert some toys to 18650 based ones? Just beware of and handle the safety concerns when dealing with 2nd hand cells in such devices and keep up the work!

Thank you!

Thank you Pete too!  (not sure why your quote is not here)....

Hmm.  We dont really have many battery powered toys.

My youngest daughter (4th grade) would probably get much more of a kick out of something like "running the fridge from batterys charged from solar panels" than from any type of toys.  Maybe this will be a first attempt at a powerwall type thing?  Possibly the load from the fridge is a lot to start with?  Maybe I will start with the light on our aquarium?
She would probably like an 18650 powered night light for her room too.
I'll have to ask her to come up with some ideas.

She wants to have a business which helps the environment.  She sat down with 2 other friends at school to do a business plan after my wife told her a business needs a business plan.
They decided on a business name, that the business is about "we recycle everything" and they wrote a long list of possible products.  I was pretty impressed with what they came up with considering they dont know what a business plan really is.
It was seeing her page full of work that made me decide to show her what I could with the laptop cells.

The 18650 holders arrived in the mail today, and she was really excited.  She asked about the "little square things for charging" (tp4056)  and when they would arrive.

I put one of the charged cellls into one of the holders and showed her the tiny sparks that happen when the wires are shorted.  I asked her "What do you think the sparks can do?"  and she said "Start a fire".
I explained that she cannot do anything without asking, and me supervising.

I suspect my older daughter will be less enthusiastic, but will be interested and learn plenty too.

Ahh! Smile

If its an older fridge that one will take alot of umph to start and its not something you start up with just a few cells. Everything with motors need to considered to take atleast 5 times or more during startup unless you know otherwise.

best is to start with lamps. For instance night-lamps is perfect! Charged during day and used during night!

Welcome - it sounds like your little one has a great head on her shoulders - the key to our planet's future is all about our kids!   I love that you are getting her involved and enthusiastic early.

re the fridge, I was thinking it would be at the "big, but not quite whole house/grid tied" end of the size of possible projects.

Thanks all, for the words of encouragement!

Its been quite a while, but it is time for an update.
Since I started extracting cells, I made a few USB powerbanks, but I was having quite a few sanyo heaters, a few zero volt packs and not able to source a lot of packs to open, so things were very slow.
However, recently I found a good source of 18650 cells!
Things are looking good for getting a decent size powerwall project going!

Another update.

So far I have extracted over 550 cells and I am hoping that the majority of the cells will be good.
Only a very small number have had low voltage. The vast majority are between 3.6 and 4 volts.
I have not sorted out what my test process will be yet.
I have a few hw586 (similar to zb2l3) testers, but over the last few days I have done some repeated testing of 1 cell, with the same charger and capacity tester and the results seem a bit inconsistent.
