hey guys. I have a toy Lamborghini Gallardo car, and it has a 7.2V Rechargable Ni-Cd battery pack. what i want to do it add an extra AA battery do hopefully give it more power. what i need to know is, what connects the all the batteries with the wire that you plug in to the other wire that connects to the car and the battery charger? whats on the batteries that conducts the electric charge to all 6 AA batteries?
NiCd or Nickel Cadmium batteries are rechargeable but doing it using your battery pack is not viable since a single recharge takes about 12 hours to complete. A better option is to buy an NiCd battery charger from your local store, which can charge upto 6 batteries within 2 hours. Make sure you completely drain out thebatteries before you recharge them because if you don't the residual electrodes get converted into a stone like substance which becomes unusable, thereby shortening your battery life and battery charge.
take two battery packs hook the 1 red wire from one and one black wire from the other together, Then hook the left over wires to the car like normal. (you will have to cut and splice some wires. this will give you twice the power.
