dnmun said:don't cut the battery pack open, just cut the plastic sleeve that is on the BMS lengthwise on the backside from one end to the other in the middle so you can fold it back over the BMS later.
that BMS is the same as the hi current signalab without the leds. you measure the first cell voltage between B- spot and the first pin on the sense wire plug, where the pins are soldered to the BMS. put the black probe on one pin and the red probe on the next higher pin, measure to .01V using the 20V scale and post them up so we can tell you what to do next.
I'm going to wait a few days before I decide whether or not to cut into it, btw there is no obvious bulge or anything on any of the surfaces of this brick...if there had been I would already be there.
The brick is in fact gaining almost .1v after a nights charging.
