Build your own USB Powerbank from reclaimed 18650 cells that you can recharge with a USB phone charger. I can accommodate complete beginners as well as those with experience of Lithium batteries and LEDs. Charge mobile phones and power LED lighting in the field!
Laptop batteries, medical devices, modern power tools, cordless home appliances and more recently vaping devices contain 4.2V Lithium Cells. These are often of a particular size: approximately 18mm wide by 65mm long, thus the name 18650.
There are lots of 18650s out there as well as many other form factors of reclaimable and useful rechargeable Lithium cells. Lithium cells are much longer lasting than traditional Lead-Acid cells and often outlive the cheap disposable devices they are inside. Lithium battery packs sometimes get thrown away if one cell in a pack dies, as the whole pack may become useless even though the rest of the cells are fine.
If you bring any of these lithium battery packs or cells, we can test to see if any of the cells can be reclaimed. If you don’t have these, I will provide you with 4 x 18650 cells reclaimed from portable medical devices.
Sign up for this course in person on either Thursday or Friday at Radical Bakers Summer Gathering by talking to me. There are 6 places with first-come, first-served.
Included in the course are:
4 x reclaimed 18650 Lithium cells and a 3D printed holder
1 x 2A QC PD 5V Powerbank Module PCB
Consumables: solder, Nickel strip, Copper cable, Heatshrink.
I will be asking for a donation of £10 to cover the materials if you can afford it.
I will also have lots of low voltage components and 12V Gadgets for sale in the Camp Market including: LED strips, bulbs, fittings and dimmers, Battery management systems, 12V timers, Sensors, Switches, fuses and fuse holders, solar connectors and cable, solar panels, lithium cells and more. Interesting things for people doing their own DC wiring and off-grid electrics.
Blake from Green Dragon runs his stage at events from solar panels and battery power. He has been wiring up small scale DC systems for the last 15 years. Solar panels are cheaper now and easily in reach of anyone who wants power off-grid. Green Dragon is powering the whole site including kitchen blenders and site lighting.
