Thanks for the reply
Yes, but I moved the discussion to the (old) Nexus 7 forum when I discovered this is the forum for the 2013 Nexus 7. See this thread for updates: http://forum.xda-developers.com/show....php?t=2311799

From pictures it looks like the 2013 version also has a LiPo battery with about the same specs and wires, but I'm not sure.

I'm preparing a permanent install of a Nexus 7 (2012 but maybe 2013) in my '04 VW Polo without the battery in it. I'm worried about fluctuating temperatures and the heat inside the dash when the heater is on as the vents run through it.

After a couple of Google searches I came across this thread and was wondering if you have you discovered any more drawbacks to directly powering the tablet? If it's still running fine at 5v that is...

Check out this video for some ideas: https://www.youtube.com/watch?v=pTgH...e_gdata_player

The dude uses the inductive coil in the nexus 7 to charge it wirelessly and holds the tablet in place with neodinium magnets. Pretty cool setup!

Violence has its own economy. Therefore, be thoughtful and precise in your investment.

Same here. I've also experienced almost bricking the device when the battery went flat. Went through hell to make it charge the battery. Batteries don't work very well in cold temperatures, and up in the Norwegian mountains it often goes below -25 C (-13 F).

In case you missed it before. I posted in the wrong forum, so I haven't tested on the 2013 version of Nexus 7, but the first gen. Also I haven't had much time to test this, and only powered it by 5V for a few hours at the time. See the (old) Nexus 7 thread for how I got it connected to my computer again: http://forum.xda-developers.com/show....php?t=2311799
