in system it show not installed, no orange light, not running from battery alone.
Checked the usual suspects R7051 - R7052 - R7021 - R7022 all seems fine, a bit stucked at this point.

Disconnect BIL and try again, also could be bad ISL or bad SMC, all this assuming you already tried other known good battery
