are many ways to drain the battery down to safe levels. I have heard the
lipos are 'safe' anywhere below 2V per cell, however, I figure as long as
I have something draining them, I just leave them on the load until they are
basically 'dead'.</span></font></p>

anything up to 3 cells, I use an automobile tail light bulb. Just solder
2 leads onto the bulb at the 2 contact points and clip the other ends onto the
battery leads. For a 5 cell pack, I would use 2 bulbs in series.
Put them in a safe area, clip the bulbs on and leave them for a couple
days. Check the voltage from time to time and when it gets down to about
zero, just throw the battery in the trash.</span></font></p>

the salt water bath approach and it didn't do anything for me. After a

work. A large resistor, light bulb, old brushed motor, etc.</span></font></p>
