Key Features 

 
Here are a few of the features of the eLogger: 
 

 

Logs pack current to +/- 100 amps (150 amps with MPRV4-LEADS-150) and voltage from about 5 volts to 80 
volts  

 

Current is measured with a true Hall Effects Sensor - NOT a power robbing resistance shunt  

 

Adjustable logging rate (from 50 samples per second to one sample every 5 minutes) 

 

16 times the logging space of the standard eLogger V3, and lossless data compression.     Typically logs all 
available sensors for about four hours, at 10Hz. 

 

All data are logged to permanent memory, which retains the data even when the power is removed 

 

Fully compatible with our OSD Pro expander 

 

Includes Y cable for throttle position logging 

 

Great for bench monitoring of battery charging also!  

 

Supports the PowerPanel LCD Display 

 

Accepts optional inexpensive sensors for  three Temperatures,  RPM (brushless, magnetic or optical), Airspeed, 
Altitude, GPS, Servo Current, and more 

 

Software computes Wattage, mAH, etc. for complete e-flight data.  

 

Fully Compatible with Windows 7 (32 and 64 bit), Vista, 98SE, ME, Win2K and XP™ 

 

Weighs about 0.8 oz (22 grams). Versions with Wire Leads may weigh slightly more. 

 

Comes with our state of the art Windows virtual playback display and graphing software 

 

Powerful Graphing software has advanced charting features, such as amps vs. volts 

 

Internet Updatable firmware - as we add new features or (heaven forbid) have a firmware bug, the update is just a 
download away! No need to ship hardware back and forth. 

 

Full support for English and Metric units.   

 

Software has built in English, German and Chinese languages.
