Clearwater Voltage Sentry (CVS) Battery Monitoring Device
Many of our customers outfit their motorcycles with additional electric devices to optimize the enjoyment of riding. However, it is important to always monitor battery health, especially when touring. The Clearwater Voltage Sentry (CVS) Battery Monitoring Device ensures you are always informed of your motorcycle battery's charged state. With an accuracy better than 1/4 of a percent, the battery monitor features a simple green, yellow and green LED display system with six levels of battery voltage. To use, simply mount the monitor to the fairing and mount the LED indicator in riding view. With the Clearwater battery monitoring device, you'll always know your bike is good to go.
A simple two wire connection is all that is needed. One connects the unit directly to either constant power or switched power. A clever "power down" routine is designed into the device to eliminate any excessive power usage. The indicator LED is only illuminated when either the engine is running (thus indicating a charging system status) or for a short time period after the engine is turned off. After the device determines that the engine is now off, it initiates a timed sequence to display the battery voltage for short period (5 minutes). Then it shuts down the LED (saving what little power is used by an LED). The computer constantly checks for any change in voltage that would indicate a need for a "re-display" of voltage status. The computer uses only microamps of current to perform this "sentry" duty. Far more power is lost in the battery due to natural self discharge. So, when the engine is off, the sentry displays battery voltage. When the engine starts, it displays maximum system voltage. There is no need to make separate battery and alternator connections with our system. If you want to review the battery voltage, just turn on the key for a second and the computer will instantly wake up and light the correct color LED. Now you can monitor both without fear of draining the battery. The simple to mount CVS displays all three colors needed.
Wide temperature variations are common on outdoor vehicles and Clearwaters design is impervious to any "human" survivable temperature. From -40 degrees up to 200 degrees, Clearwaters CVS is dead solid accurate.
Without strapping a high quality Volt meter onto the triple clamp and monitoring voltages around town, the CVS allows instantaneous monitoring of your battery/alternator system. This system is the most accurate voltage monitoring device of its kind anywhere. Accuracy is better than 1/4 of a percent.
The Clearwater Voltage Sentry is a very useful and accurate tool to monitor voltage. If the light is green, you are good to go; yellow means there is a slight cause for attention. A red light conveys that your battery is definitely not charging; shut off accessories one at a time until you get a green or slow flashing green condition. If you are running a pair of Clearwater Krista Lights on your bike (total power usage 72 watts) you might only need to switch off your high beam to lower your power usage while stopped at a light. Once you get moving again (and spinning your alternator faster) you can switch back to high beam or the high setting on your heated garment.
You can very easily tell if additional accessories are drawing more power than your bike can supply. A simple Green/Yellow/Red LED displays 6 stages of battery voltage.
Flashing Red: Indicates Less than 11.5 volts. Not a good condition for any battery. Get a charger on this battery ASAP and check to see if it will come back to life. Chances are, it may need replacing.
Solid Red: Indicates between 11.6 and 12.0 volts. Weak battery, start and run the engine for a while or get it on a charger.
Solid Yellow: Indicates between 12.1 and 12.4 volts. Acceptable battery condition, Poor to weak charging condition.
Solid Green: Indicates between 12.5 and 13.1 volts. A good charging range.
Slow Flashing Green: Indicates between 13.2 and 14.6 volts. Excellent situation. Your alternator is doing it's job.
Fast Flashing Green: Indicates over 14.7 volts. Bad situation. The alternator is overcharging and may damage your battery. Have the alternator and or voltage regulator checked immediately.
All you have to remember is: "GREEN IS GOOD"
Vibration is not an issue as all of our parts are securely mounted directly on a high quality multi-layer PCB. To further improve reliability, each assembly is sealed in epoxy in an injection molded enclosure.
As this product is completely controlled by software, Clearwater can change all the parameters with code. If an application is needed for a different voltage indication range (say Li-ions in your new Tesla) Clearwater can easily make the change. Clearwater also have a voltage "map" for the new Li-Fe batteries such as the popular "Shorai" batteries.
