[RE-wrenches] Older iCel System Lithium Ion Batteries

[Darryl Thayer]

Gary I have been told that below a certain voltage the LI-ion cells suffer
a permanent death.  I believe these batteries are small cells in
parallel.strings  and then series connected strings. to make the
voltage.can you use a lab power supply to start the charge?  I purchased
one for about 60 to 90 $ that allows me to adjust the voltage and limit the
current until the battery gets up to voltage IF it ever does..
