INSTALLED BATTERY BACKUP SYSTEM

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 cables, including those connecting the product to the vehicle’s electrical system must be protected from being damaged or

shorted. 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 which 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 connection can be made directly to the vehicle’s negative battery terminal with 4 AWG or larger copper cable. Similarly, the positive connection

should provide a low resistance electrical connection to the vehicle’s positive battery terminal with 4 AWG or larger copper cable. In order to allow high

current amperage to flow freely, no fuse should be used in the electrical path.

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 owned and/or licensed by Voxx International.

Overview

The POWV3.5 is an on-board battery backup system to provide 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.

Features

FEATURE

BENEFIT

Smart Charging

The POWV3.5 charges its internal battery when needed when the engine is running.

Dual Activation Methods

The POWV3.5 can be activated by pressing the GO/Status button on the system itself or by remotely accessing

the system using a mobile device with the Voxx Power System mobile app.

Auto awake

The POWV3.5 wakes itself up if a vehicle start was attempted, but the vehicle failed making it ready to provide

a jumpstart, and allowing it to be connected to a mobile device using the Voxx Power System mobile app.

Pre-charge vehicle battery

The POWV3.5 provides a pre-charge function that charges the vehicle battery prior to starting, which assists

the jump-start process and enables successful jump starts under circumstances where other jump-starters

would fail.

High voltage battery

The POWV3.5 uses a higher voltage battery than most jump-starters which provides for an effective pre-

charge of the vehicle battery and provides for a more powerful jump-start to start your vehicle when other

jump-starters would fail.

High-capacity battery

The POWV3.5 uses a high-capacity battery to provide the starting power to facilitate multiple start attempts

under the most demanding circumstances.

Battery heater

The POWV3.5 has an internal battery heater that automatically warms the internal battery allowing for

successful jump-starts at temperatures down to -25C.

Deep sleep mode

When the vehicle is idle, the POWV3.5 enters a deep sleep mode that allows the internal battery to stay

charged for > 6 months.

Short circuit protection

Triple redundant high-current and short-circuit protection safely prevents activation if the POWV3.5 is shorted

and de-activates the POWV3.5 if shorted after being activated.

IP67 Rating

The POWV3.5 has an IP67 environmental rating meaning it can stand up to the harshest vehicle environments

including being submerged in water for short periods of time

Mobile App

Allows for remote activation of the POWV3.5 without having to access the physical device.

Accessories

The POWV3.5 is supplied with two vinyl insulated barrel butt connectors to connect the systems power/ground leads to the vehicles electrical system.

NOTE: The POWV3.5 has 6 AWG power/ground leads coming from the device. The supplied barrel butt connectors accommodate 4 AWG cable for

extension runs to the vehicle’s battery.

The POWV3.5 is supplied with two 60mm Heat Shrink tubes (red and black) to protect the POWV3.5 6 AWG power/ground connections.

General Installation

Suggested POWV3.5 Mounting Locations:

Because the product requires direct connection to the vehicle’s electrical system, it should be installed by a qualified professional installer. Installation

of battery backup systems require 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 would be exposed to extreme temperatures or physical damage.

Figure 1- Under Seat Figure 2 SUV- Luggage Area Figure 3- Trunk Area

NOTE: The POWV3.5 system has 6 gauge Positive and Negative leads coming from the unit (8” length). These leads will need to be extended and

connected directly to the vehicle’s battery. The unit releases a massive current to the vehicles battery when activated. Depending on where the system will

be installed in relation to the vehicles battery, you will need to determine the proper cable gauge needed based on the length of the run.

POWV3.5 Cable Routing:

Basic electrical wiring precautions should be taken when routing cables from the POWV3.5 to the vehicle’s battery. When routing cables under carpet,

along door sills, and through firewalls, precaution should be taken to NOT crush, slice, puncture, or damage cables in any way. Make sure that wires

routed through a vehicle firewall or trunk are passed through a grommeted opening and are protected in wire loom.

POW3.5 Battery Connection

Because the POWV3.5 is an auxiliary power source to provide a jump-start assist, it must be connected parallel with the vehicle’s battery to operate.

The ground connection should provide a low resistance path to the negative terminal on the vehicle’s battery. Similarly, the positive connection should

provide a low resistance electrical connection to the positive vehicle terminal of the vehicle’s battery. Because high currents will pass from the POWV3.5
