If the batteries are in series the total voltage is the sum. If two equal batteries are connected in parallel the voltage will be the same as a single one. You have to be very careful though. If you connect a 5 Volt battery in parallel with a 1.5 Volt battery, they will get into an argument about which voltage to be at.
