This is the Hobbico Digital Voltmeter Mk III battery tester.  This tests 4, 5, and 8 cell R/C batteries in a no-load or a simulated R/C load setting.  These are a must for all R/C pilots.  This can prevent a crash of your airplane or helicopter due to a dead battery.

FEATURES:

• Custom designed LCD shows voltage in clear 1/2" numerals, plus customized characters to easily determine the meter setting and condition of the battery under test
• The LCD not only displays the voltage, but the voltage mode, "OK" and "RECHARGE"
• Test 5 cell packs, in addition to 4- and 8-cell batteries
• Includes a common 9V internal battery, located inside an easy-access compartment
• Built-in simulated R/C load of 250mA for each setting
• Includes two input controls: a small pushbutton on the left side of the case, and a 3-position slide switch on the face of the meter
• Switch load OFF and use it as a true Digital Voltmeter
• Measures DC voltage up to 19.99V, making it versatile enough for any DC battery - transmitter/receiver packs, starter batteries, and
  glow starter batteries
• A 10 minute auto-timer shuts the unit OFF automatically if left ON by accident, to help prevent unwanted battery drain
• Rubber grip for no-slip handling
• Color coded banana jacks, compatible with most common test leads
• One year limited warranty.
