OWNER’S MANUAL

Congratulations
Congratulations on your purchase of the POWV3.5 Battery Backup System! This product has been designed to provide you with peace of mind that you will always have a  reserve power source to start your vehicle in the event your main battery fails. Please read the directions that follow to familiarize yourself with the product to ensure you obtain the best results from your equipment.

Safety Precaution
The POWV3.5 contains a high-power battery that is not user-replaceable. No parts of the product are user-serviceable. Because the product requires direct connection to the vehicle’s electrical system, it is highly recommended that the POWV3.5 be installed by a qualified professional 12v installation technician. The POWV3.5 is to be installed inside of a vehicle’s cabin or trunk, and as such, it is important to use the proper gauge cable to maintain the current needed for the operation of the POWV3.5. It is also extremely important that the power cable is protected from being damaged or shorted in its run from the POWV3.5 to the vehicle’s battery. The POWV3.5 is designed with built-in protection circuitry to protect itself, but it will not prevent possible damage to the vehicle in which it is installed if the power lead from the vehicle’s battery to the POWV3.5 is shorted. If you have any questions or problems with your product, please contact a Voxx certified retailer, installer, or Voxx Technical Support at 1-800-645-4994.

Important Notice
Installation of the POWV3.5 requires careful planning and preparation. The POWV3.5 should be installed under a seat or in a trunk, in a location where the GO/Status button can be accessed, and the indicator LEDs are visible. It should not be installed in the engine compartment or any other location where it will be exposed to extreme temperatures.

Because the POWV3.5 is an auxiliary power source that provides a jump-start assist to a vehicle battery, it must be connected in parallel with the vehicle’s battery to operate. The ground connection should provide a low resistance path to the chassis (if the vehicle has a negatively grounded chassis) or a connection can be made directly to the vehicle’s negative battery terminal. Similarly, the positive connection should provide a low resistance electrical connection to the vehicle’s positive battery terminal. The gauge of cable to  be used is dependent on the distance from the POWV3.5 to the vehicle’s battery (See Installation Manual for Wire Gauge/Distance Guide). To allow high current amperage to flow freely once the POWV3.5 is engaged, no fuse should be used in the electrical path since most 12v fuses and/or circuit breakers are not designed to withstand high current amperage flow. This also requires special attention to wire routing so that no potential shorting of the power cable occurs.

Warnings
Do not place or store items near or on top of the POWV3.5 to avoid damage to the system.
The POWV3.5 is covered by multiple patents licensed to Voxx International.

Overview

The POWV3.5 is an onboard battery backup system to provide an emergency jump- start (boost) in the event the vehicle’s battery is too weak to start the vehicle. It is wired in parallel to the vehicle’s starter battery and self- regulates its charge while the engine is running so that it is always ready for use. When needed, the POWV3.5 can be activated by pressing the GO/STATUS button or by using the mobile app. Once activated, the POWV3.5 provides a short pre-charge to the vehicle battery for approximately 5 seconds, following which the vehicle may be started. The POWV3.5 will detect when the engine is running and will automatically deactivate itself.

Flashing Blue – Battery is cold. Multiple jump-start attempts may be required.

Operation

Once installed into a vehicle, the POWV3.5 wakes up and begins charging its internal battery when the vehicle is running to draw power from the alternator and not the vehicle battery. It continues to charge until it is fully charged, or the vehicle stops running and the unit goes into sleep mode. If charging is not complete when the vehicle stops running, it will continue charging the next time the vehicle is running. This process continues until the internal battery is fully charged. After the initial charge, the POWV3.5 will re-charge its internal battery as needed when the vehicle is running in order to sustain its full charge.
Waking the Unit
The POWV3.5 wakes automatically when the car starts running or when there is a failed vehicle start attempt. The unit may also be wakened manually by pressing the  GO/STATUS button once. When the unit wakes, all the LEDs flash once, and the status LED will slowly blink green indicating that the unit is ready to use if needed, unless the engine is running. The unit stays awake for 10 minutes after activation or continuously while the engine is running, and the internal battery is charging. While the unit is awake,  the Bluetooth radio is active allowing connection with a mobile device running the Voxx Power Systems mobile application.
Connecting with the Mobile App
While the unit is awake, the user can connect with the POWV3.5 using the Voxx Power Systems Mobile app by opening the VOXX Power Systems mobile app and selecting the  POWV3.5 attached to the user’s vehicle. (See Page 13)
Jump-Starting
Jump-starting a vehicle is a two-step process after the unit is activated; 1) pre-charging and 2) vehicle starting. The POWV3.5 is activated by pressing and holding the GO/STATUS button while the unit is awake, but engine is not running, as indicated by the STATUS indicator slowly flashing Green. The POWV3.5 may also be activated using the Voxx Power Systems mobile application running on a mobile device.
Pre-charging
First, the POWV3.5 is activated which starts a vehicle battery pre-charge interval that lasts for about 5 to 15 seconds. The pre-charge supplies a charge to the vehicle’s battery which greatly assists the jump-starting process. During the pre-charge interval, the POWV3.5 is connected electrically to the vehicle’s battery and the STATUS INDICATOR  blinks Yellow rapidly. While it is possible to start the vehicle during the pre-charge interval, it is recommended to wait until the interval is complete before attempting a start to ensure the greatest likelihood of success on the first attempt, especially in the most demanding circumstances such as extreme cold.

Vehicle Starting
When the pre-charge interval is complete, the status indicator will illuminate steady Green and you will have 30 seconds to attempt to start the vehicle. If no attempt is made, the  POWV3.5 will go back to the awake state, ready to be activated again. After completing a successful start, the unit will automatically deactivate. While the POWV3.5 can provide 10 to 20 jump starts when fully charged, the POWV3.5 may limit the number of jump-starts attempts to prevent the battery from overheating by de-activating the system. If that occurs, the TEMP INDICATOR will illuminate Red until the unit is ready to activate again.

Temperature Extremes
The POWV3.5 will operate under wide temperature ranges, however, jump-starting performance may be limited or restricted under certain circumstances. The TEMP indicator will provide information about the internal POWV3.5 battery temperature when the unit is activated. If the POWV3.5 battery is within the normal operating temperature range,  the TEMP indicator will be illuminated Green when the Go button is pressed on the POWV3.5 or the unit is activated using the mobile app. If the internal battery is below its ideal operating temperature, the TEMP indicator will flash Blue and The STATUS indicator will alternately flash Yellow and Blue until the internal battery heater warms the battery to the proper operating temperature. If the internal battery is above its maximum allowable temperature, the TEMP indicator will illuminate Red indicating it is too hot  to use.

Cold Weather Operation
The POWV3.5 can provide a jump-start down to -25C, however, below certain cold thresholds, the internal heater must warm the battery prior to use. Like all batteries, the internal battery efficiency decreases at low temperatures, but the POWV3.5 is equipped with an internal heater that will warm the battery to bring it up to proper operating temperatures prior to activating the pre- charge feature. While the internal battery is warming, the TEMP LED will flash Blue and the STATUS indicator will alternately flash  Yellow and Blue while the POWV3.5 remains disconnected from the vehicle battery. After the battery has reached a minimal operational temperature, the POWV3.5 will initiate the precharge feature for approximately 5 to 15 seconds and then the POWV3.5 is ready to provide jump-start assistance. Note, the internal battery heater will continue to warm the POWV3.5 battery during this time, increasing its efficiency since more than one start attempt may be required while the battery continues to heat.

Hot Weather Operation
The POWV3.5’s internal battery can be permanently damaged if it is used to jump-start a vehicle when its temperature is above 60C. Therefore, the POWV3.5 will prevent activation when its internal battery exceeds this temperature. This will be indicated by the TEMP indicator illuminating solid Red and the STATUS indicator flashing Red. If this situation arises, allow the POWV3.5 to cool by increasing air circulation around the unit. This can be achieved by opening doors, windows, the trunk, etc. and waiting until the POWV3.5’s internal temperature falls to a safe operational range that will be indicated by the TEMP indicator illuminating solid green upon activation.
