Batteries Plus or your local computer store maybe good places to find old
battery packs. Just ask the clerk if you have an old dead LiIon Battery Pack.
i just got an old HP Laptop battery pack and 4 of the 8 cells were good.
i got 4 good Sanyo 4UR18650-2-7 LiIon batteries out and charged them and now
i have a nice external 14.4VDC supply for my KX1 at 2.3 AmpHour.
The pack weight is only 6 oz.. The cells are 2.3 " x 0.75" each.
Do not exceed the 3.700 V charging voltage, Google your mfgr's spec sheet for
maximum charging voltage.
You may have to learn how to charge them.
They have NiCad's and NiMH's too...
