Designing a DIY Battery pack
Many people have built battery packs out of both Nickel and Lithium based batteries for their own personal use. Maybe as a battery bank for a Solar system or for a smaller use case. I have been contemplating to build my own version of a standardised(ish) DIY battery pack. One that I could use for multiple applications.
I will be using 18650 Lithium-Ion batteries mostly harvested from disused laptop battery packs. If you have access to laptop batteries in chances are that you would be able to salvage at least some of their cells for this use. The challenge for the future in this respect will be the ever thinner laptops are using more custom battery cells than 18650 cells in order to become as thin as possible. Another source could be surplus battery packs for discontinued laptops and other battery operated appliances. These would then be available for purchase at sell-out prices.
