Trolltek™ has expanded its lithium battery range with the release of the 12V 100Ah Super Slimline LiFePO4 Lithium Battery with Bluetooth – a compact, high-performance battery designed for installations where space is at a premium.
At just 55mm thick, the new Super Slimline battery provides 100Ah / 1280Wh of lithium capacity in a low-profile format ideal for 4WDs, canopies, caravans, campers, marine applications and custom auxiliary power systems.
Whether you're building a new touring setup or upgrading an existing auxiliary battery system, the Trolltek™ Super Slimline provides a practical way to add serious battery capacity without sacrificing valuable storage space.

The standout feature of the new Trolltek™ battery is its remarkably slim design.
Measuring approximately:
525mm (L) x 270mm (310mm including feet) (W) x just 55mm (H)
and weighing approximately 15kg, the Super Slimline format opens up installation possibilities that simply aren't practical with a conventional battery case.
Depending on your vehicle or setup, it may be suitable for installation:
Behind vehicle seats
Against canopy walls
Beside drawer systems
Inside compact caravan compartments
In camper trailer electrical systems
In custom marine installations
Wherever conventional battery dimensions are difficult to accommodate
For 4WD touring builds in particular, making better use of otherwise wasted space can be extremely valuable.
Despite its ultra-slim dimensions, the Trolltek™ Super Slimline delivers:
12V | 100Ah | 1280Wh
This makes it a highly versatile auxiliary battery for powering common touring, camping and marine accessories such as:
12V fridge/freezers
Camp lighting
Water pumps
USB chargers
Phones and tablets
Marine electronics
Caravan accessories
Communications equipment
Selected inverter applications
LiFePO4 battery technology also offers strong usable capacity, low weight and excellent cycle performance compared with traditional lead-acid battery technologies.
Knowing what's happening inside your battery is much easier with integrated Bluetooth monitoring.
The Super Slimline includes a Bluetooth-enabled Battery Management System and connects to the free Trolltek app for iPhone and Android, with no subscription fees or advertising.
From your phone, you can monitor important battery information such as:
State of charge
Battery voltage
Charging status
Discharge current
Remaining battery capacity
Battery performance
BMS information
This is particularly useful when you're camping, touring or boating away from mains power.
Instead of guessing how much battery capacity remains, you can check the battery directly from your phone.
Inside the Super Slimline is an integratedBattery Management System (BMS) designed to protect the battery and help maintain reliable operation.
Protection includes functions for:
Low voltage
High voltage
Over temperature
Short circuit protection
Cell balancing
The battery supports up to 100A continuous charging, 100A continuous discharge and a 280A maximum pulse current, making it suitable for a wide variety of demanding auxiliary power applications when correctly installed and matched to the load.
The Trolltek™ Super Slimline has been designed with installation flexibility in mind.
In addition to its M6 terminals, it features:
1 x 50A Anderson connection
1 x 120A Anderson connection
This provides convenient options for connecting compatible chargers, accessories and electrical equipment without requiring every connection to be made directly to the main battery terminals.
For touring builds where equipment may need to be removed, upgraded or reconfigured, quality plug-style connections can make the system considerably easier to work with.
Space and weight are always important considerations in a 4WD.
Once you've installed a fridge, drawers, recovery equipment, tools, camping gear and water storage, finding room for a conventional auxiliary battery can become difficult.
The 55mm Super Slimline design allows the battery to make use of narrow areas within a touring setup.
Combined with a suitable Trolltek™ DC/DC charger, it can form the heart of an auxiliary power system for:
Fridge/freezers
Lighting
Camping accessories
USB charging
Water pumps
Communications equipment
Other 12V accessories
For vehicles where every centimetre of cargo space counts, the Super Slimline format can make a significant difference.
The same compact dimensions also make the battery well suited to caravans and camper trailers.
Electrical compartments can quickly become crowded once chargers, fuses, solar equipment and other electrical components are installed.
A slimline battery provides greater flexibility when designing the system and may allow valuable storage areas to remain available for other equipment.
With 100Ah of capacity, the Super Slimline can provide auxiliary power for common caravan and camper loads including lighting, refrigeration, water pumps and device charging.
The Trolltek™ Super Slimline can also provide a compact auxiliary battery solution for appropriate marine installations.
Potential applications include supplying power to:
Fish finders
GPS equipment
Marine lighting
Radios
Pumps
General onboard electronics
Other compatible 12V equipment
As with any marine battery installation, ensure the battery is installed in a suitable location and that all cabling, protection and charging equipment is correctly specified for the environment.
Trolltek™ lithium batteries use new UL-certified cells and reinforced internal construction designed for demanding environments.
The Super Slimline is rated for an operating range of -20°C to 60°C, although charging below 0°C is not recommended. The battery carries an IP43 enclosure rating and is specifically noted as not recommended for under-bonnet installation.
For most 4WD installations, this makes locations such as a canopy, cargo area, behind-seat mounting position or other protected auxiliary battery location the better option.
LiFePO4 technology is well known for its cycling capability.
The Trolltek™ Super Slimline uses new UL-certified pouch cells and is specified as capable of6,500+ cycles based on 50% depth of discharge, while Trolltek states approximately 80% capacity retention at 3,000 cycles under recommended conditions.
For users who regularly discharge and recharge their auxiliary battery, this can provide a major advantage compared with traditional lead-acid battery technologies.
Need more capacity or a higher-voltage system?
The Super Slimline supports battery bank configurations including:
Parallel connection: Multiple batteries can be combined to increase total Ah capacity while keeping the system at 12V.
Series connection: Up to four compatible batteries can be connected in series to create systems up to 48V, subject to Trolltek's installation requirements.
For example:
2 x 12V 100Ah in parallel = 12V 200Ah
or
2 x 12V 100Ah in series = 24V 100Ah
Always ensure batteries are appropriately matched and follow the correct series or parallel connection procedures.
The Super Slimline is also available as part of Trolltek™ battery bundle configurations.
Depending on how you use the battery, you can pair it with suitable charging equipment for:
240V AC charging
DC/DC charging while travelling
Solar charging as part of a compatible system
Choosing a battery and charger bundle can make it easier to put together a matched lithium power system without sourcing each component individually.
The Trolltek™ 12V Super Slimline Lithium Battery is backed by a 5-year warranty, providing additional confidence for customers investing in a long-term auxiliary power system.
The new battery brings together several of the features customers look for in a modern auxiliary lithium battery:
Super slim 55mm profile
100Ah / 1280Wh capacity
Only approximately 15kg
Bluetooth monitoring
Heavy-duty integrated BMS
100A continuous charge capability
100A continuous discharge capability
280A peak current
