Using the Boyer version, it’s basically like adding a capacitor but all built into the one box, you just disconnect the fuse to the battery and run the bike. The bike will perform just as if the battery was connected and working fine.

If you do fit one of these, I’d suggest fitting a fuse to it also. (Although in your case I’d do that even with the standard unit, then if you do start it again you should only pop the fuse)

Now let’s all have a beer beerchug
