Really need it compact and battery life for two days.
I could use a Wifi transmitter I guess.

Perhaps Bluetooth is enough.

You could also use various separate components and make your own - a
microcontroller with whatever A/D inputs you need, and a Flash socket
for recording. There are numerous library routines for writing to Flash
drives, or you can try a library that offers FAT-16 compliant storage if
you need to read it on your PC.
