Please help me figure out these lithium pouches

Is it normal for the battery to take this long to charge? Going from 2.05v to 2.17v has taken roughly 4.5 hours @.3 -.5amps.

What "pack" configuration are you charging now ?
4 cells in series ? Or 4 in parallel, or just a single cell ?
Either way though, that 0.3 amps for 4 hrs is only 1+ Ahr into a 13 Ahr cell, so dont expect the voltage to move fast.

Single cell for right now. If it works on the one I will start doing 4+ at a time. Is there a better way of charging multiple batteries: Series vs Parallel?

I raised it to .6 and it seems to be moving a little faster and still staying cool to the touch.

What charger do you have ? When charging numbers aren't linear. It may take a long time to 4.1 volts, but after that it's off to the races 4.15 then 4.2 and it's gone like a rocket ( puff ). Just letting you know as soon as you get to far away things happen.
I have a voltsphere single cell lifepo4 charger stops at 3.6v 2 amp. I would hook 4 in parallel and put in barbeque. Check voltage. Let set and check voltage. Get rid of runts. Then put on charger. Not for kitchen table. Because you want to walk away don't you ?

I have the the IMAX professional. I think it is the real version..

Changed the charger from NiMH to NiCD and she is charging much faster. Up to 3.10v now.
