V6 PCB: 233718 FU-Dyson-BMS compatible?

[Boysolder]

Greetings enthusiasts, great inspirational read for a novice like myself...,well outside my comfort zone and loving it. V6 battery on last legs, but still working albeit briefly, looking at upgrading stock VTC4 cells with HJ2, and if that goes well will update the firmware. Case opened successfully, removed 1 cell and PCB 233718 "not listed" (looks very similar to 188002) or SVxx! Pictures attached, if BMS firmware is compatible will grab a PICKit 3.5 and dive in head first. Thank you in advance. Cheers Boysolder!
