Designed for Real-World Touring

Whether you're running a caravan air conditioner through an inverter, powering a large off-grid electrical system, or simply wanting longer runtimes between charges, the Alpha Series 300Ah battery provides the storage capacity needed for demanding applications.

Its compact design helps maximise available storage space while integrated rope handles make installation and handling significantly easier.

Smart Monitoring at Your Fingertips

The integrated Bluetooth-enabled JBD Battery Management System allows you to monitor battery performance directly from your smartphone.

Using the Exotronic Alpha Series Battery App, you can view:

• State of charge

• Battery voltage

• Charge and discharge current

• Individual cell voltages

• Battery temperature

• BMS alarms and protection status

Having real-time visibility of your battery system helps eliminate guesswork and provides confidence when travelling off-grid.

Built-In Pre-Trip Low Battery Alarm

One of the standout features of the Alpha Series range is the integrated pre-trip warning system.

When battery state of charge falls to 10%, the battery activates a visual and audible alarm for up to 60 seconds, helping alert users before power becomes critically low.

This simple feature can help avoid unexpected power loss and allows charging to be arranged before the battery reaches shutdown protection.

Its IP67-rated enclosure provides excellent protection against dust, water and harsh operating conditions, making it ideal for:

• Caravans

• Camper trailers

• Motorhomes

• Marine installations

• Commercial vehicles

• Off-grid power systems

The sealed design helps protect internal components from moisture, dust and vibration commonly encountered during travel.

Advanced Battery Protection

At the heart of the battery is a 300A JBD Battery Management System featuring comprehensive protection against:

• Overcharge

• Over-discharge

• Short circuit

• Excessive charge current

• Excessive discharge current

• High and low temperature conditions

The battery also features active cell balancing to help maintain long-term performance and maximise cell lifespan.

Premium Internal Components

The Alpha Series uses high-quality aluminium-cased prismatic LiFePO₄ cells featuring integrated safety rupture discs and IEC 62619 certification.

Combined with solid brass terminals and low-resistance connections, these components help improve efficiency, reduce voltage drop and support long-term reliability.

Expandable Power Capacity

For larger systems, multiple batteries can be connected together to increase storage capacity.

The Alpha Series supports:

• Up to 4 batteries in parallel

• Up to 4 batteries in series

allowing system configurations of up to 16 batteries where required.

Simple On / Off / Reset Function

The integrated control button makes operation straightforward:

• Press once to turn the battery on

• Press again to turn the battery off

• Press twice to reset after a protection event

Alternatively, a suitable lithium charger with dark-start capability can be used to reactivate the battery.

Suitable Applications

The Exotronic 300Ah Alpha Series battery is ideal for:

• Caravans and RVs

• 4WD touring vehicles

• Marine applications

• Tiny homes

• Off-grid solar systems

• Backup power systems

• Commercial service vehicles

Please note this battery is not designed for engine starting or under-bonnet installation.

The combination of IP67 protection, Bluetooth monitoring, active balancing, integrated low-battery alarm and premium prismatic LiFePO₄ cells makes the Alpha Series one of the most feature-rich lithium batteries available for serious off-grid power systems.
