820-00923 crashes on battery, on charger all fine

Client had repaired liquid damage in some other shop.
They replaced battery and on the board I can see liquid damage around:
UB600, J5260, QV300, UB300

When on battery there are random restarts with kernel panic.
"*** Panic Report ***
panic(cpu 0 caller 0xffffff801f342836): nvme: "AppleS3XController. Loss of MMIO space. Write. ID=0xffffffff ARG1=0xffffffff ARG2=0xffffffff ARG3=0xffffffff EDD0=0xffffffff EDD1=0xffffffff EDD2=0xffffffff EDD3=0xffffffff EDD4=0xffffffff EDD5=0xffffffff EDD6=0xffffffff EDD7=0xffffffff NANDV=0x2, DRAMV=0x1, SSDC=256G.\n" @IONVMeController.cpp:6053
Panicked task 0xffffff854c2516a0: 188 threads: pid 0: kernel_task"

When on charger then all works fine even during CPU stress test.

Tried with know battery and got the same issue.

Any idea?

Any error pops up starting in diagnostic mode (battery connected)?
The best option is testing with known good ORIGINAL battery (even old one).

No error in diagnostic mode (battery connected).

Tested with original used battery and same issue.

One thing which is not right and dont know if it will be related:
J3300/47 USBC_XA_D2R_P<2>in diode mode 0.004 and should be around 0.330

D3326 is the first suspect; remove it and check again.
If still short, bad U2800.
