A DIY USB power bank made from an old laptop battery @ DoItYourselfGadgets: A situation many can relate to: an empty smartphone battery and no outlet around! That’s exactly why I recycled an old laptop battery into an USB power bank. This article will show you the basic powerbank circuit consisting of Lithium cell charging circuit, […]
Disconnect circuit for 12 volt lead acid and lithium batteries
https://www.electronics-lab.com/50967-2/
KA7OEI designed a circuit that disconnects the battery when it over-discharges. He writes: The avoidance of overcharging is usually pretty easy to avoid: Just use the appropriate charging system – but overdischarge is a bit more difficult, particularly if the battery packs in question don’t have a “protection board” with them. Lead acid batteries (almost) […]
