Czech Sports Cruiser PS28 Factory Build with twin D1000 FMDs - Location of SV-BAT-320

[Vincent Barnes]

Does anyone have a diagram of the cockpit panel for factory-built Czech Sports Cruisers with twin Dynon D1000 MFDs? I need to replace the left SV-BAT-320 backup battery and want to understand where it is located. The Czech Sports manuals have no such pictures. Thanks!
