BatteryShark UPS Battery Failures

Posted in Uncategorized on December 29, 2015 by brandon314

Fully charged 48 volt pack in an APC DLA3000RM2U. Individual measurements made on pack with light load. The two cells marked with “X” are failed badly and there is a 3rd weak cell. Weak/failed cells were moved to one series string upon discovery so that the UPS would pass a self-test without shutting completely down and risking system shutdown.

Batteries are <12mo old and have <5min of cumulative draw on them. Float charge voltage shown in last photo. System runs with 9-11% load.

Cell 1 – 12.20V

Elevation Profiles for Portland, OR (PDX) to Black Rock City, NV (BRC)

Posted in Uncategorized on December 10, 2012 by brandon314

For those of us who have naturally aspirated heavy vehicles, these graphs may be of some use.

Thanks to http://www.gpsvisualizer.com/elevation for the tool!

 

The standard route (I-5 South to Hwy 58 to Hwy 97 to K-Falls to Hwy 139 to Hwy 299 to Hwy 447 to Gerlach, NV) Shortest with most pre-elevation low-altitude driving (better MPG at lower altitudes).

Elevation 58 to 97

 

 

This route is very similar except travels up over 26 and directly onto 97 (lots of higher altitude driving and a fair amount of decent/climb. (Hwy 26 E to Hwy 97 to K-Falls to Hwy 139 to Hwy 299 to Hwy 447 to Gerlach, NV)

Elevation 26 to 97

 

This route is using Hwy 22 out of Salem. (I-5 South to Hwy 22 to Hwy 97 to K-Falls to Hwy 139 to Hwy 299 to Hwy 447 to Gerlach, NV) Not as much low altitude driving as the 58 route, but it does have a nicer climb profile.  I’ve done this route and it’s not too bad but you definitely notice running up around 3000-4000ft right off the freeway.

Elevation 22 to 97

 

This is the ever popular route that uses Hwy 58 but passes by SummerLake hot springs. (I-5 South to Hwy 58 to Hwy 97 to Hwy 31 to Hwy 395 to Hwy 299 to Hwy 447 to Gerlach, NV). The length is a bit longer than the K-falls route and has a few more random bumps with steep peaks along the way, but the SummerLake option is a nice one.

Elevation 58 to 31

Hope these are useful!
