This is likely some issue with a sensor checking in. This is almost always the case after a battery repair. It’s possible the new battery is defective. Or the battery connector on the board sustained some damage during the repair. The data pins in particular are prone to bend.

Can you post a copy of the full panic report? Or at least screenshots of the first page or so?

@store0667 The panic you posted indicates pretty much what I expected. There is a battery sensor (TG0B) which the iPad is not getting communication from. The issue is going to most likely be the new battery, or damage to one of the pins on the battery connector. I would recommend taking the board out to inspect the underside of the battery connector.

How did you disconnect the battery before disconnecting the screens? Or what did you use? Does as mentioned before sound like damaged pins on the board. A pain but remove the board completely and take a look for damage.
