I can now repair most lithium batteries which use 18650 cells, as most do. Including: laptops, power tools, ebikes, vacuums (including Dyson), etc.
Also upgrade nicad/nimh batteries to lithium.
I’m working on a conversion system to allow interchangeable ‘standard’ batteries within the same voltage (ie. 12, 14, 18, 36v).
I’m happy to take any old lithium battery packs for recycling.
And I’d gratefully receive any assistance in the project including crowd funding potential.
Have a perfect genius day
