Overview:
It's late in the afternoon, and you've been boating most of the day. The wind has finally subsided, and there's just enough time for one more run before the sun sets. You're ready; how about your batteries? With Expert's V300 Voltmeter, you'll know in seconds if it's safe to float or if it's time to recharge.

The Expert V-300 Voltmeter features an LED bar graph display. 10 LEDs (3 green, 4 yellow, and 3 red) are displayed in a bar graph for easy viewing on the current state of charge of your receiver battery pack. Each LED's color corresponds to that of a stoplight: green for go, yellow for warning, and red for stop-do not fly before recharging. Switch selectable, you can test both 4-cell and 5-cell receiver packs under a 300 mA current load to simulate the typical operating current.

Using the V-300 is very simple: Move the slide switch to correspond to the appropriate voltage level of the pack being tested (4.8V 4-cell or 6V 5-cell) and plug the V-300's universal connector into the charge jack. In 10 seconds you have an accurate and stable reading, so at a glance you know if you can safely go boating.

This is the VoltWatch2 on-board Receiver Battery Monitor for
4.8V and 6V NiCd and NiMH receiver packs.
This mounts on the outside of the airplane, so you can see at a glance
the status of the receiver battery mounted inside.

FEATURES: 7-LEDs provide instant, accurate battery voltage status of Low, Safe,
or Max. Only one LED glows at a time
Small switch to select 4.8V or 6V battery
Very lightweight, only .15oz (4.3g) unit can mount on the side
of the fuselage, or under the plane's canopy
Draws amazingly low current - from 4-34mA depending on the battery
voltage
Plugs into any open receiver channel using a Futaba J connector
One year warranty
