really appreciate your reply. But can you explain to me why not use cell phone batteries to power my car? I was thinking it was a pretty good idea, because I just had two batteries that were unused, and cell phone batteries are small, portable. I even have cleared the middle of the car for holding the batteries. My car is really not that big, It is just 15cm * 8cm * I don't know the height yet. Are there any ways that I can make use of those cell phones batteries?
Thanks.
