Batteries in portable equipment

Recommended Posts

Not enough info, what is it? What voltage? What is the expected use and run time? How much current does it require, is it constant or erratic? Used inside or outside, in winter?

Hey,

here is more information:

The device will be a braille decoder to be used inside a classroom in school. It will send data via Bluetooth to a computer. Expected use is about 4 tot 8 hours a day.
Voltage is not yet determined as we have not set the specs yet of the device, it will either be:

3V8 and 3V3 => power supply 40mAh

or

3V6 to 4V9 and 5V continuous (for USB) => power suply 125mAh

I would go for a Li-Po since they are light weight and small for a handheld device like this. Perhaps it is a good idea to use a replacement battery for a cell phone, they are nice and compact. The one I have got in my cell is 6 x 39 x 65 mm 3.6Volts and 1200mAh 26g as an example. ;)
