Do you think that this would be ok? Hi I am Making on of these for a school project but I can not find the Inverter that you used but I can get one that is a 47 uF.

There is a graph on the datasheet that is Input Voltage versus Output/Load Current. That indicates the inductor to use. Actually I just found my own answer, but please feel free to add to it.

I don't have any laying around and not overly familiar with them. The datasheet says to use 68uH, but yours looks like 56uH. Is that just "in the ball park" component?

Be sure to try to find a charger that uses a switching regulator. Many of the cheaper ones use linear regulators, which waste most of your battery's power in heat. Sounds like fun.

I added a thermistor to the pack to help the charger detect when the pack is fully charged. The pack and the charger came from batteryspace.com.

It's not hard to generate those voltages (just four resistors), but most older chargers don't do it, because when they were made, it wasn't necessary.

I decided on a 12 V sealed lead acid battery. I will take a 4AH and a 7 AH battery with me and use a car adapter. I am doing testing now, but it looks good. I dont plan to use the phone but I will be able to take video, stills, and listen to music. Hey Dave
