I've got 16x 100ah cells. Initially tried to parallel all of them and get them up to 3.6.
I only had a dinky 5amp CCCV gadget and at 3.3v it was pushing ~2 amps. I imagine it would have taken a year to top balance at that rate. It ran for 48 hours and the voltage didn't move at all.
So I broke them into packs of 4p. I also ordered the bench top supply that Will recommends.
Got the bench supply today. Read the book. Hooked it up to a small 12v pack I have to test it. Had it set on 13v and no current. Clipped it onto the pack, the leads got red hot, heard some popcorn, and released the magic smoke. (pictures attached)
Plan B.
I have some "20 amp" CCCV chinese gadgets. Tuned one to 3.6 volts and cranked up the current. Battery voltage is 3.31 - Only pushing 2 amps.
Are my expectations wrong?
