ALLiON batteries’ Lithium Iron Phosphate (LiFePO4) cells provide superior thermal and chemical stability compared to other lithium technologies.
Their wide operating temperature range also ensures ALLiON batteries deliver reliable power every time, making them the perfect adventuring companion for RVs, motorhomes and caravans.

ALLiON Lithium Batteries have been designed to provide market leading performance and safety. Using LiFePO4 technology, these batteries deliver several key advantages compared to existing lead acid battery technology.

Thermally and chemically stable LiFePO4 technology is safe and durable, delivering many years of reliable operation. The superior cycle life lowers the cost of ownership by reducing the number of battery replacements and the high discharge/recharge rates mean ALLiON
batteries can deliver more power, more often to power your adventure.



ALLiON batteries’ high energy density delivers around 60% weight reduction compared to equivalent AGM lead acid batteries. The lower weight means safer manual handling and a lower overall weight of your energy storage system.

Safe & Stable LiFePO4 technology

LiFePO4 technology is well regarded for its thermal and chemical stability. ALLiON batteries are safe and durable, fully capable of delivering many years of reliable operation. Unlike lead acid batteries which need external ventilation to prevent explosive gases accumulating, LiFePO4 does not vent any gas during operation. Full sealed in this way, ALLiON batteries can also be safely mounted on their side
and installed in compact spaces without having to worry about venting.

Partial State of Charge (PSoC)

Lead acid batteries are happiest when they are fully charged (100% SoC). Operating at PSoC increases the rate of sulphation which directly reduces battery performance
and cycle life. Sulphation is not an issue for LiFePO4 technology so performance and cycle life is not affected when operating at a PSoC. This means ALLiON batteries will
still deliver all of their benefits in applications where they are being charged by variable energy sources like wind and solar.

Onboard Battery Management System

The Onboard Battery Management System within ALLiON Batteries protects the battery if voltage, current or temperature vary outside the designed operating range.

Excellent Cycle Life (2,000 to 4,000 cycles)

ALLiON batteries are rated for 2,000 to 4,000 cycles depending on the Depth of Discharge (DoD). This means even with deep discharging, an ALLiON battery will deliver
2,000 cycles whereas a deeply discharged lead acid battery equivalent will deliver around 300 cycles. This huge increase in cycle life means less battery replacements, reducing the overall cost of ownership.

Fast Recharge with Overcharge Protection

ALLiON batteries’ flat discharge curve delivers full power for an extended period of time. The higher charge acceptance of LiFePO4 technology means that even a deeply discharged battery can be charged safely & efficiently in less than 3 hours.






AS/NZS 3001.2  | New regulation requirements:

The new regulations for lithium batteries require a few considerations when installing in caravans as of 15.11.2023. It is therefore recommended to take the following recommendation into consideration when installing:


Lithium batteries shall:

  • Be installed externally, ie. Behind a wall, compartment or barrier that prevents the egress of gases into the habitable area; and
  • Not enter the habitable area of the structure


In order to meet these requirements, it is recommended that lithium batteries be installed as follows:

  • Open to the environment, taking into account a suitable IP rating and mechanical protection.


  • Located in a battery compartment that is sealed to the enclosed habitable space of the recreational vehicle.


A battery compartment that opens to the exterior should

  • Open outward (to the exterior of the connectable electrical installation) and
  • Be accessed from the exterior of the recreational vehicle


If access to the battery compartment is obtained from within the habitable space of the recreational vehicle the compartment must have the following:

  • Fitted with openings that maintain a full seal from the enclosed habitable space of the recreational vehicle when in the closed/stored position
  • Access to the compartment must only be possible by removing screws or using a prescribed tool.
  • An adequate seal from the enclosed habitable space of the recreational vehicle must be restored and maintained after removal and replacement of the compartment opening.


Sealing of a battery compartment from the habitable space of the recreational vehicle must ensure the following:

  • The construction of the compartment must prevent the ingress of any fumes or gases from entering the enclosed space of the habitable area.
  • Any cable penetrations into the battery compartment must be sealed with suitable cable glands bulkhead posts or another form of non-combustible sealing.


  • An annex is considered a habitable space of a recreational vehicle. Battery compartment openings should be located outside the expected enclosed space of an annex.


Note the definition of a recreational vehicle by Cambridge university is:

a large motor vehicle in which you can sleep and often cook, used for traveling and camping

This would include Caravan’s, motorhomes, camping trailers.
