Hi, all sold at the moment. Message me for how many you’re looking for and where you based and I’ll see if I can source them

Hi Guys. Sorry for such a late post. I came across 18650 packs, a lot of them. Selling them at R15 per pack of 100 packs. Or cheaper for more. For less would have to discuss but at R20 per pack. You can come see and pick up. They’re mostly dell/Lenovo/hp etc. Untested sealed still. Hit me up with a message if interested.

Hi

So I 3d printed cell holders for the Batterries, soldered on the fuses, hooked them together 7p, got a 24V cell meter balancer. And connected the terminals to the battery connection on the inverter. I’d say tested the cells and built the battery from scratch.

They’re still as laptop batteries. Sell them per laptop battery . The amount of cells depend on which battery it is

Hi Stok. On average , when I tested, I had usually all were good, or 4 were good, or all were bad per pack. Depends on the pack. The average Mah can vary, but I managed to make about 3x 24V packs with about 280 cells, all above 2000mah, some closer to 3000mah. I’d say a definite good yield of about 50% cells made it to my power wall.

Hi guys I came across more second hand laptop Batterries if anyone is interested. I can give them to you for R10-R15 a laptop battery, depending on how many you take. I’m based in midrand. They’re perfect for DIY powerwall and small projects! there is too many for me to add to my power wall.

Cool. PM sent

I’ve come across some used laptop Batterries for sale. Untested. Let me if you’re interested. Based in Gauteng.

Hi Guys Im not sure if its here to ask, but im planning to buy some panels, maybe a hybrid inverter which would be most of the costs for my system during this black Friday specials. But the one things that I would still require, is someone to do the installation for me. Can anyone refer me perhaps to someone who does this and that's reasonably priced? Ill need the system to get a CoC after the installation as well. Id really appreciate your feedback. Regards

Thanks for the info! Will do some reading up on the 3s layout to better understand. Ive managed to get this setup today,

Hi Guys, I'm planning with the sizing of my Li ion battery packs, and need to know how to limit the voltage of the cells to about 4.0V per cell, instead of 4.2V and also perhaps the discharged limit to about 3.1V - 3.0V. I plan on building a 4S 40P Li ion cell pack, to give around 1kwh pack, and part of the issue, is to control the upper and lower limits. Your recommendations would be highly appreciated. Regards

Ah I’m in sunninghill jhb! Hmm, yeah! Thanks for the great gesture! I may take you up on it in the future, let me do some ground work as well! Thanks

was contemplating getting a 3d printer for the printers, also to have the flexibility of customizing the holders like to allow for recessed bus bars and fuses, voltmeters, etc. I decided to think about it later and see how far I get for now. Ill take some pictures and start a thread to capture my progress in another section of the forum. Thanks for the welcome and input.
