The car is currently powered by 12 -12 Volt Hawker Odyssey AGM batteries (144 volt -105ah). I have plans to replace these with a Li-ion battery pack which will have twice the capacity and be a third of the weight. With the current configuration it has about a 35 mile range on a 3 hour charge. Max calculated speed is 170mph. So far I have only had it up to 85mph, but there was plenty of power to keep going.
