If I were you esp in a competition I would want a charger so I'm always getting full voltage. In the least I would bring a fully charged spare battery incase there's an emergency. I would hate to hear about a semi old battery slowly loosing it's charge and failing. These bikes suck alot of electrical power at full throttle.

Just because you run a 24v start isn't going to increase the longevity of the primary battery by much. No matter what route you follow 50 starts with only a very very short time to recharge is going to take a toll on your battery. I hope you disconnect the headlight during racing.
