    Trouble Selling Cells

    Hi, I know this isn't the right place for sales, but I've tried selling my 18650 cells on the marketplace, facebook, and ebay but had no interest. Any tips on where to sell them? I've got 770 cells, mostly around 2200-2300 mAh cheers

    Around 700 18650 cells. Lincolnshire, UK.

    Hi Matt Thanks for your reply. The majority are well over 2000 mAh. I'd like 700 for the lot. I've got some exact numbers of cells and capacities (770 cells): (I've recently found a few more cells and have updated numbers) 2800-2899 mAh = 2 2600-2699 mAh = 24 2500-2599 mAh = 32 2400-2499 mAh...

    yes, that would have been sensible! It was more of an experiment with some bits and bobs that I had, so that I could learn from it. I plan to build a bigger system to power part of the house at some point.

    Hi, thanks for all your replies. When I went to put a diode on the panel side of the system, I realised that I'd already put one in ages ago! Doh! I think the logical explanation is that the inverter is draining the battery as suggested by Redpacket. I wanted the system to work so that I just...

    Although that solution worked, my battery is draining overnight. Do I just need to put a diode on positive feedback from solar panel?

    Thanks so much for your help, I will try that. Just waiting for it to cool down a little it's 31 degrees c here. Not used to it in the UK! That worked a treat, thanks very much for your help Korishan. Onwards and upwards!

    So I've finally got around to doing some troubleshooting. I've connected the battery straight to the inverter and plugged my LED strip lights into it. This works fine. I've measured 12.8v on the load output of the charge controller. If I connect the charge controller to the inverter it still...

    Hi, thanks for your replies. The inverter is rated at 1950w, although I was using a little 100w inverter that somebody gave me, and that did the same thing. There is a guage on the new inverter that reads 240v ish when unloaded. I've attached photos. I've been collecting 18650s for a while and...

    Hi, I'm having trouble with a small project I've been working on. I have a 10w solar panel going through a cheap chinese 12v/10a charge controller into a 12v/24ah lead acid battery. I then have a cheap chinese 12v to 220-240v inverter with 2x 36w LED strip lights connected via a standard (UK) 3...

    Powerwall Calculator

    Thanks, that's interested, but I'm thinking of something you can plug in your kwh/d load, and it will tell you your pack sizes based on 6v, 12v, 24v etc. Then will suggest inverter and charge controller size, and also solar panel sizing based on geographical location (sunlight hours per day)...

    Powerwall Calculator

    Hi, has anyone designed a powerwall calculator which calculates the whole system based on required load? This includes battery pack sizes, charge controller, inverter, solar panels etc etc. I know there are a lot of variables, but it would be very useful. I know Javier Camacho has made a basic...

    Take it easy, man. Exciting project! I've just had to have a break from my powerwall project too, but I'm back in the game with 50 laptop batteries to process!
