It is not common to use 24 volts for a race car It is common to use 2 12 volt batteries in parallel. If that does not work, you have other issues. Also I would have your present battery load cell tested to see if it is in good condition. 16 volt battery is another option and the rest of your electrical system should work without other changes. Optima batteries have gotten a bad reputation since the company moved their production out of the USA and quality suffered. Maybe borrow a known good battery and see if anything changes. Those AGM style batteries require a special charger is they get low on voltage, below 10.5.
