Which MOSFET to use for battery voltage measurement?

Hello all,

I'm currently building a buoy with a string of sensors that measures temperatures at different dephts. I'll be making a blog or Something Else later.

The thing is, I want to measure the voltage of the battery (Li-Po) to be able to predict when it needs to be charged since the system will operate "out-there-in-the-middle-of-nowhere".

Super Cooler Code

Hi guys as some of you know I've been working on code for a project I have in mind, it not a new idea, lots of folks are doing it http://freeaire.com/ , I just want to put my take on it, and perhaps save some store owners some money and make a little myself.

 I live in Maine USA, winters are pretty cold here, lots of small stores have walk in coolers for keeping beer and soda code, so why not when its suitable use that cold air to cool the walk ins, a typical 8' by 20' walking cooler costs $250 or more a month in electricity to operate.
