Here is my opinion about charging your race car. NO ONE has ever lost a race because the battery was charges....period. Why not charge between rounds, what else is going on? If you normally don't have to charge your battery all day, what happens when the battery gets weak, or the car takes longer than normal to cool-down. You wouldn't be the first person to lose because the car would not start.....
Charge your battery, be ready to race.................
