Panasonic Lithium Ion

       Remove this ad - become a site supporter!
Hey guys. Would these batteries have any practical use for electric flight. They're 3.7v 2550mah capacity and 46gram each. I pulled them from a laptop pack. The pack had 3 deal cells but the other 6 showed 3.75v(good according to the Panasonic battery site). Could I use 2 cells to replace a 7.2 nicad or 7.4v lipo. How about charging? Will a lipo charger handle these? Thanx in advance..

Low C rate

The cells may be alright in a low C application, say 5 to 8. The ones that you feel are toast may also come back if charge at a very low rate say 100 mah. The pack in the PC probably got out of balance as they don't utilize balanced charging, at least not any any laptop old enough to end up in the scrap bins at work. I've salvaged a few batteries over the years, but don't forget to keep them in a fire resistant location while checking them out and charging them (Terracotta planters etc.)
