Clean board, came in with an X on the battery, replaced D7050 and the ISL, now battery is recognized and charges fine, but when the charger is disconnected the Mac runs for about 1-3 minutes then shuts down even with the battery holding a %50+ charge.
Resistance between pins 17/18 and 27/28 of U7100 were all correct, I checked that from the start, same with the known working battery, only thing that made a difference was reballing the SMC.
