It starts fine once warm, so is that a case of more ampere hours or amps needed to turn it for a longer period?

Does anyone know what the largest battery battery is that can fit in the bike. The battery in there is sold as a scooter battery, and perhaps I should be getting something bigger as long as the physical dimensions fit ok.
