DIY external laptop battery from recycled cells.Easy project but you need a specialized Li-ion charger.I use IMAX B6 , with balancing and works fine. This pack is a 5 cell in series for around 19V 2.5AH..like 45Wh..and it can be used like a power supply for laptop, soldering iron, even amplifiers or WIFI...cameras..anything working in between 16-21V.I charge it from my solar panels via IMAX, consider a recycle green project.
