Building a lithium battery system can quickly become confusing when you're trying to work out which battery, charger and accessories you need.
Trolltek™ Lithium Battery Bundle Deals make the process easier by combining compatible LiFePO4 lithium batteries with charging equipment and selected accessories in one convenient package.
Whether you're upgrading a 4WD, setting up a boat, fitting out a caravan or building an off-grid power system, choosing a bundle can help simplify your setup while also offering better value than purchasing components individually.
Trolltek currently offers bundle options across 12V, 24V and 36V battery systems, with both 240V AC charging and DC/DC charging options available.
A battery is only one part of a complete power system.
You also need to consider how the battery will be charged, how it will be installed and whether the charging equipment is suitable for the battery voltage and chemistry.
A Trolltek™ bundle helps take some of the guesswork out of this process by combining products designed to work together.
Depending on the bundle selected, your setup may include:
Trolltek™ LiFePO4 lithium battery
Compatible AC or DC/DC lithium battery charger
Battery cables and connections
Voltage Sensitive Relay (VSR) where applicable
Battery securing accessories
Bluetooth battery monitoring
All Trolltek™ lithium battery bundles include access to Bluetooth battery monitoring through the Trolltek app for compatible iPhone and Android devices.
One of the biggest advantages of choosing a battery bundle is value.
Rather than purchasing a battery and charging components separately, Trolltek™ bundles combine key components at a reduced package price.
For example, the current Trolltek range includes 12V, 24V and 36V AC and DC battery bundles, alongside a dedicated DC/DC Charger and VSR package.
This makes a bundle particularly attractive when you're starting a new installation or replacing an older battery system.
One of the first decisions is how you intend to charge your lithium battery.
Trolltek™ bundles are available with two main charging options:
An AC lithium battery bundle is designed for users who have access to mains power and want to recharge their battery from a 240V power source.
This type of setup can be well suited to:
Boats stored at home
Caravans connected to mains power
Camper trailers
Workshop applications
Portable battery systems
Trolling motor batteries
Batteries that are charged between trips
Simply connect the appropriate Trolltek™ AC lithium charger to a suitable 240V power source and recharge the battery according to the charger and battery instructions.
Current Trolltek AC bundle options include 12V, 24V and 36V systems, including a 12V slimline battery package.
A DC/DC lithium battery bundle is designed for applications where the auxiliary battery needs to recharge from a vehicle or engine charging system.
This makes DC bundles particularly useful for:
4WD touring
Dual battery systems
Camper trailers
Caravans
Boats
Touring vehicles
Mobile off-grid setups
A DC/DC charger manages the charging process between the starting battery or alternator system and the Trolltek™ lithium auxiliary battery.
For a 4WD setup, this can allow the battery to recharge while you're driving between campsites.
For marine applications, a suitable DC charging arrangement can allow an auxiliary or trolling battery to recharge from the vessel's charging system where the installation is designed appropriately.
Trolltek currently offers 12V, 24V and 36V DC lithium battery bundles, along with a 12V slimline DC bundle.
A 12V lithium battery bundle is a versatile choice for many common touring and recreational applications.
12V systems are commonly used for:
4WD fridges
Camping lights
Water pumps
USB charging
Caravan accessories
Marine electronics
12V appliances
Small inverter systems
General auxiliary power
Trolltek™ offers both conventional-case and slimline 12V lithium battery bundles, with AC or DC charging options.
This gives customers the flexibility to choose a battery style that better suits the available installation space.
Space can be at a premium in a 4WD, canopy, caravan or camper.
A slimline lithium battery can make better use of narrow installation areas such as:
Behind vehicle seats
Along canopy walls
Behind drawer systems
Inside compact electrical compartments
Against caravan or camper walls
Trolltek™ currently offers both AC and DC bundle options using its 12V slimline lithium battery, making it easier to build a compact system without having to source the charger separately.
For equipment designed to operate at 24V, Trolltek™ offers dedicated 24V lithium battery bundles.
These can be particularly useful for applications such as:
24V trolling motors
Marine systems
Electric equipment
Higher-voltage off-grid systems
Specialist recreational applications
Choosing a purpose-built 24V battery and compatible charger can also simplify the installation compared with building a 24V bank from multiple 12V batteries.
Both AC and DC 24V bundle options are currently available.
Higher-voltage systems are often used for larger trolling motors and other equipment specifically designed for 36V operation.
Trolltek™ offers 36V lithium battery bundles with either AC or DC charging, giving users the option of charging from mains power or incorporating the battery into a suitable mobile charging system.
Using a dedicated 36V battery can also eliminate the need to create a 36V battery bank using three separate 12V batteries, potentially reducing wiring complexity and the number of individual battery connections.
Not every customer needs a new battery.
If you already have a suitable battery and are upgrading the charging side of your system, Trolltek™ also offers a DC/DC Charger & Voltage Sensitive Relay (VSR) Bundle.
A VSR can form part of a dual-battery charging arrangement by helping control the connection between the starting battery and auxiliary charging system.
This type of bundle can be useful for:
Boats
Older vehicles
Dual battery upgrades
Custom electrical installations
The correct charging layout will depend on the vehicle, alternator and electrical system, so always follow the relevant wiring instructions.
A major advantage of Trolltek™ lithium batteries is integrated Bluetooth monitoring.
Rather than guessing how much battery capacity remains, you can use the Trolltek app to monitor battery information from your phone.
Depending on the battery model, you can view information such as:
State of charge
Battery voltage
Charging current
Discharge current
Remaining battery capacity
Battery temperature
Battery Management System information
Trolltek's current lithium range promotes Bluetooth connectivity across its batteries, allowing users to monitor battery health, performance and status through the app.
This is particularly useful when travelling, boating or camping away from mains power.
The easiest way to narrow down your options is to answer three questions.
Start with the equipment you're trying to power.
If it requires 12V, choose a 12V system.
If you have a 24V or 36V trolling motor or other specialist equipment, select the matching battery voltage.
Never choose battery voltage based solely on capacity or price.
ChooseAC charging if you mainly recharge the battery from 240V mains power.
Choose DC/DC charging if you want the battery to recharge while travelling or from an appropriate engine charging system.
Some larger touring systems may ultimately use multiple charging sources, such as:
DC/DC charging
Solar
240V AC charging
The best setup depends on how and where you use the battery.
Measure your installation area before purchasing.
A standard battery case may be ideal for:
Boats
Battery boxes
Caravans
Dedicated electrical compartments
A slimline battery may be better for:
4WDs
Canopies
Behind-seat installations
Narrow storage areas
Choosing the right physical battery format can make the finished installation considerably cleaner and easier.
A good battery system is about more than choosing a battery with a large Ah rating.
The battery, charger, wiring and electrical protection all need to work together.
Choosing a Trolltek™ bundle gives you a strong starting point by pairing the lithium battery with suitable charging equipment and available accessories.
It also makes it easier to understand what you need to get your system up and running.
Whether you're upgrading your 4WD for touring, fitting a new trolling motor battery to your boat or adding lithium power to a caravan, a Trolltek™ Lithium Battery Bundle can make choosing your equipment simpler.
With 12V, 24V and 36V battery bundles, AC and DC charging options, slimline configurations and Bluetooth battery monitoring, there's a solution for a wide range of touring, marine and recreational applications.
Bundle your battery and charger, simplify your setup and save with Trolltek™.
