I don't get putting batteries in parrell direction.... wouldent the second betterys connection make the first battery short curcuit? Need info fast because project is due tomarrow and i need to see if i can get it to be more powerful!

Connecting in Series When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours). This might be used in a scooter, Power Wheels kids vehicle, or other applications. Just use a jumper wire between the negative of the first battery and the positive of the second battery. Run your negative wire off of the open connector from the first battery and your positive off of the open connector on your second battery. Connecting in Parallel When connecting in Parallel you are doubling the capacity (amp hours) of the battery while maintaining the voltage of one of the individual batteries. This would be used in applications such as laptop batteries, some scooters, some ups backups, etc. Use a jumper wire between the positives of both batteries and another jumper wire between the negatives of both batteries. Connect your positive and negative wires to the same battery to run to your application.

Batteries are not connected internally. There is a substance called a dielectric (or insulator) that keeps the positive and negative sides of a battery from being in contact. Therefore you can hook up as many batteries as you want in parallel and you will never short your circuit. Hope this helps.

Merely connecting two batteries in parallel does NOT make a circuit. If the batteries are any good then they want to shoot electrons out one end and collect them at the other. However, connecting them in parallel won't get you more power; it will get you more endurance. If it's power in the terms of volt-amps you seek, then series is the way to go. Wiring batteries in parallel won't increase your voltage, and amp-draw has more to do with the resistance of the circuit than with the batteries. All wiring batteries in parallel does is net more amp-hours; the same amp-draw for more hours.
