I have been looking for a small SD data recorder with at least two ad channels, battery opperated to run for two days. I need 120 sps roughly and the resolution is not that important. I'll keep looking, but help plese. It will be for EEG. Most of that stuff is transmitter based.

Do you want to buy, or design one? I case you wanted to build something: I could add a PIC LOL to my SDcard based 12 V powered WAP54G wireless access point so it stores 120 samples of say 10 bits per second.
You're off by a factor of 1000.
There are things a bit like that around. Try
to start with. They may not do exactly what you want, but you'll get some useful search terms to google with, and an idea of what's available. If you can't find a radio based one directly, you could perhaps buy some other kind of module (a receiver) to connect to the datalogger.

You are right, 1150 hours, or 47.9 days. Cool.
Lascar only has slow interval rates. I did find a unit that will work, except its limited to battery life, something like 23 hours. This might work, don't know the cost. its specifically for what I want by CleveMed.
