What you are describing on your racing setup sounds more like an umbilical type setup. We use something similar with our really small race batteries on grand Prix bikes. The batteries only run ignition and data -- starters are not on board. When the data engineer needs to plug in to download data or upload new maps, an umbilical is plugged in so the tiny race battery is not drained.
The important thing to remember with Lithium batteries--ALL lithium batteries, regardless of manufacturer-- is not to over discharge them. If they get below 10.5 volts they typically cannot be resurrected and become a paper weight. This is one advantage of lead acid, they are very robust when it comes to an over discharge state and can sometimes be saved.
