DC to DC Battery Charger™ by Wagan Tech®

1www.wagan.com

Thank you for purchasing the DC to DC Battery Charger™ by Wagan Tech®. With

normal care and proper treatment, it will provide years of reliable service. Please

read all operating instructions carefully before use.

The 25A and 40A DC to DC Battery Chargers are designed to provide the

optimal charging characteristics for your auxiliary battery from either your

alternator or external solar source. The solar controller is designed with

Maximum Power Point Tracking (MPPT) to maximize the power coming from your

solar panels up to the maximum rated output. The DC to DC chargers also allow

you to select either vehicle power or solar power priority and is programmable

for all common types of automotive lead acid batteries and LiFePO4 type starting

batteries.

CAUTION

• Do not charge a LiFePO4 battery when temperature is below 32ºF (0ºC).

• Do not operate the battery charger unless you have read and understood

this manual and the charger is installed as per these installation instructions.

We recommend that the charger be installed by a qualiﬁed person.

• The battery charger should not be used by persons (including children) with

reduced physical, sensory or mental capabilities, or lack of experience and

knowledge, unless they are supervised or have been instructed on how to

use the appliance by a person responsible for their safety.

• Do not alter or disassemble the Battery Charger under any circumstances.

• Only use the battery charger for charging 12V standard automotive lead

acid, Gel, AGM, Calcium or LiFePO4 type batteries.

• Check the manufacturer's data for your battery to ensure that the maximum

voltage of the proﬁle you select as shown in the "Charge Control" section

of this manual does not exceed the manufacturer's recommended max

charging voltage. If the max voltage is too high for your battery type,

please select another charging proﬁle.

• Check the mfg's data for your battery to ensure that the "Continuous

Current Rating" of the charger does not exceed the mfg's recommended

max charging current.

• When using the Battery charger to charge a Lithium Iron Phosphate battery,

only batteries that feature a built-in battery management system featuring

built-in under and over voltage protection and cell balancing are suitable.

This charger is NOT compatible with other lithium ion or metal battery

types.

• The battery charger is not intended to supply power to a low voltage

electrical system other than to charge a battery

• Cable and fuse sizes are speciﬁed by various codes and standards which

depend on the type of vehicle into which the Battery Charger is installed.

Selecting the wrong cable or fuse size could result in harm to the installer

or user and/or damage to the battery charger or other equipment installed

in the system. The installer is responsible for ensuring that the correct cable

and fuse sizes are used when installing this Battery Charger.

• Never smoke or allow a spark or ﬂame in the vicinity of the battery or

engine. this may cause the battery to explode.

• To assist with the safe operation and use of the Battery Charger when

connected to the battery:

• a) wear complete eye and clothing protection. Avoid touching eyes

while working near a battery.

• b) If battery acid contacts your skin or clothing, remove the affected

clothing and wash the affected area of skin immediately with soap

and water. If battery acid enters your eye, immediately ﬂood the

eye with running cold water for at least 10 min and seek medical

assistance immediately.

sWARNING: Risk of explosive gases: Working in the vicinity of a lead-acid

battery is dangerous. Batteries generate explosive gases during normal

operation. For this reason, you must follow the instructions when installing

and using the charger.

It is very important that all wire extensions are well connected, to ensure the

stable and reliable operation of the product. For your convenience, butt splice

connectors have been provided. After a secure connection is made, use the heat

shrinkable tubing or electrical tape to completely cover any exposed wiring to

prevent a short to surrounding metal.

Notes:

• Disconnect the negative battery cable (Earth) from the vehicle’s starting

battery before installation.

• If your vehicle has a ﬁxed voltage or temperature compensating alternator

(standard alternators) installed, leave the Ignition Override cable (BLUE

color) open. If your vehicle has a smart (variable voltage) alternator

installed, the Ignition Override cable must be connected to the vehicle’s

ignition. The Battery Charger will only operate when the vehicle’s ignition

is turned on.

All recommended fuses should be connected in series in circuit. Bolt down fuses

are preferred because they ensure a low resistance connection. Blade-type fuses

are not recommended as they can result in a high resistance connection which

causes excess heat and may damage the fuse holder and/or the wiring. Self-

resetting circuit breakers are not recommended as they may trip prematurely due

to the heat generated by the current ﬂowing through the wires.

FEATURES

The Battery Charger is speciﬁcally designed for charging auxiliary batteries. It

includes all the features needed to maintain an auxiliary battery at its optimum

condition and to prolong battery life.

Superior 3-Stage Charging

Using a high speed microcontroller and proprietary charging algorithm, the

Battery Charger delivers a sophisticated 3-stage charging process resulting

in a faster and more powerful charge, ideal for deep cycle batteries. The ﬁrst

stage, bulk (constant current), charges the battery faster while the second stage,

absorption (constant voltage), ensures the battery is thoroughly charged. The ﬁnal

stage, ﬂoat, maintains the battery at a safe voltage, allowing it to be maintained

and ready for use indeﬁnitely.

FloatAbsorptionBulk

Multi-Chemistry Support

The Battery Charger supports Standard Lead Acid, Gel, AGM, Calcium content

or LiFePO4 batteries. The LiFePO4 battery charging algorithm of this charger can

activate the lithium battery with BMS protection.

Switchmode Technology

The Battery Charger converts your vehicle’s 12V DC/24V DC alternator power to

a 12V system; allowing your batteries to be fully charged, prolonging battery life

and reliability. With the latest synchronous switching technology, the efﬁciency of

the Battery Charger is up to 95% at a typical full load condition.

Dual Input Operation

The Battery Charger allows two energy sources to power your auxiliary battery.

Solar input takes precedence if solar input power is strong enough. When solar

input cannot provide enough energy to charge the battery, the Battery Charger

will draw power from the alternator. It supports both 12V and 24V alternator

input, and also supports the Smart Alternator system input.

Solar Priority

The Solar Priority function allows for you to prioritize solar charging over

charging from your alternator. As long as the solar panels produce more than

25W (for 7410) or 50W (for 7411) of power, the unit will select charging by

solar. If the auxiliary battery decreases below a certain level, the unit will charge

by alternator regardless of solar input.

Solar MPPT Optimized Charging

The Battery Charger utilizes sophisticated MPPT (Maximum Power Point Tracking)

solar regulator technology. MPPT maximizes the power generated from the solar

panels to the auxiliary battery. The maximum power point tracking efﬁciency is

up to 95%, creating a maximum charging current of 25A/40A.

Remote Monitor (Optional)

An external remote monitor (Part. No. 7400) is available to show the status of the

charger. It shows how the auxiliary battery is charged by the alternator or the

solar panel, and other useful information.

SAFETY PROTECTIONS

Spark-Free Protection

The Battery Charger will not start charging the battery (no output) unless the

load is securely connected (except the LiFePO4 mode which allows 0 volt start). It

prevents the output leads from sparking due to accidental short circuit making the

charger safer to use around batteries.

Reverse Connection Protection

Reverse connection on input and output terminals does not damage Battery

Charger internal circuit. The Battery Charger will not charge if output connections

are reversed.

DC to DC Battery Charger™ by Wagan Tech®

13 www.wagan.com

Over and Under Voltage Protection

The charger will automatically shut down if there is an over voltage or under

voltage problem.

Over Temperature Protection

The charger will lower its output current if the temperature of the unit begins to

overheat.
