Right off the bat it appears I overcharged it for roughly 30 minutes. No swelling occurred but I'm attempting to try and understand the current voltage drop from my discharging. I believe I possibly damaged it permanently via overcharging, but so far I'm not sure if the 2.74v discharge at 10a right now is damage, needs recharging due to overcharging, or really the voltage drop

As you can see the charging for over 4 hours at 4.1v x 10 amps... this is the most I could constantly pull out of my DC supply without the voltage bouncing around.

Discharge charts will be up in a few hours once the testing is completed... Results are not looking so great at 0.25C as far as voltage drop

As I posted yesterday... the voltage drop is significant even when only draining at 10 amps of current out.... this is PRIOR to the overcharging sin I committed (battery was charged to about 20% capacity at this point)
