Recharging an RC car with NonRechargeable Batteries
I got my little sister these little rc cars made by tomy. they have infrared to avoid obstacles and navigate themselves (pretty cool) but they burn through batteries very quick. it uses 2 x AA non rechargeable batteries so i want to make them rechargeable. Here is my problems with current ideas, and the pictures really help explain everything so please look there.
1 normal rechargeable batteries --- will have to remove battery door every time and it is too much hassle
2 use rechargeable battery pack for wii like below -- not as common and expensive
3 heres the one that might work
incorporate a 3v rechargeable power source with a dc charger port and 2 indicator leds, all in an enclosed 2 x AA battery holder HOW???
please help --- i just want to make it work out but i really dont care if i have to change the batteries or anything like that also, i need to make 2 of these so cheap please!!!
and maybe add another led for the car to have a glow like pic 4?
