Unlike MTH, Lionel locomotives do not need batteries to operate. The ONLY function of a battery (or a BCR) in a Lionel loco is to provide power for the sound system during brief power interruptions and shut-down. Your Vanderbilt will function just fine without any battery at all.
Having said that, and as Dave mentioned above, you need a charging circuit if you want to use the BCR with Lionel. The photo you showed is of a stock Vanderbilt tender with RailSounds 2.5. If you have can post the instructions for the charging circuit, we might be able to figure-out how it gets wired into the tender.

Hello guys and gals......
I have a Sunset 3rd rail S.F large steamer and came with lionel railsound 4.0 which uses a 9 volt battery to keep the sounds running but the engine will run without the battery installed. I stored the engine with battery OUT.
