[RE-wrenches] Older iCel System Lithium Ion Batteries

[Gary Rochlin]

Yes they are – I took one of the packs apart and each battery is made up of 7 packs of 16 Panasonic CGR1865D Panasonic LI Batteries.  I think if we do a test charge and see if we can get the voltage to increase it will be an indication the battery is still good. Thank you for your Input.

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..

Does anyone have any information or specifications for an older circa 2010-2012 iCel System Lithium Ion Battery.  We are doing a repair on an older 48V Lithium Ion system consisting of 3-6 ICel batteries wired in parallel and 1 Xantrex 6848 and 2 Xantrex Conext MPPT 60 150 Solar Charge controllers.  Via a surge from SCE system shut down and sat before we were called in.  Batteries are sitting at 6.67V and the charge controller will not turn on unless the batteries are at 40V since at the time they were made for lead acid batteries.  I’m looking at finding the way to charge the iCel  batteries or goose the charge controller into thinking 40V are coming from the batteries.  I think I’m making sense here.
