Ultra Safe
The advanced Battery Management Safety System provides comprehensive protection to the battery with high precision configurable protection and monitoring features, that protect the battery and carefully manages the safe long-term performance of each individual cell and the battery pack (or a bank of inter-connected batteries).
THE BMS PROTECTION
-
-
Low Voltage Protection Switch – Automatically disconnects the discharge circuit to prevent damage to the cells if the battery drains below a pre-set voltage.
-
Over Voltage Protection Switch – Automatically disconnects the charging circuit to prevent damage to the cells if the battery is being charged above a pre-set voltage.
-
Short Circuit and Over Current Protection Switch – Automatically disconnects the discharge circuit if the discharge current exceeds pre-set limits.
-
Reverse Polarity Protection Switch – Automatically disconnects the charge and discharge circuits if a reverse polarity condition is detected.
-
Thermal protection – Built-in thermal sensors will automatically disconnect the charge and discharge circuits when excessive temperatures are detected.
The system will also report any alarm and protection statuses through its communication interfaces to allow the user to trouble shoot and identify any issues.
The batteries are independently tested to comply with the IEC62619 safety standard, is 3 certified, and also comply with the requirements of the AS/NZS 3001.2:2022 Connectable electrical installations and supply arrangements standard. giving you peace of mind for the safe, reliable, and compliant performance of the batteries.
Really Smart Communication
The sophisticated Battery Management System (BMS) not only takes care of the safe performance of the batteries, it also gathers detailed information on the battery, such as the Running State, State of Charge (SOC), Voltage, Current, Temperature, individual cell voltages, Alarm / Protection statuses etc. This information can then be accessed externally via Bluetooth with the Android or iOS app, or via the CANBUS and RS485 communication ports for integrated systems. In addition, several models can also consolidate the information of a bank of batteries through inter-connected links, allowing a single “host” battery to act as the communication gateway to the entire bank.
The CANBUS interface is compatible with various inverters, chargers and communication gateways, such as the Victron Multiplus and GX devices to provide enhanced integration.
Dry contact relay outputs are also available on some models, which can trigger an external signal in the event of an alarm condition in the batteries.
For professional installers requiring more advanced integration, the batteries can be connected to a PC via an RS485 communication port, allowing monitoring from PC based software with the ability to make certain advanced adjustments to the BMS parameters, or to develop customised integration via the RS485 communications protocol. The software and communication adapters are available from Amptron to qualified customers.
External Colour Display
An optional colour screen display can be added to the battery system to display battery information. The display will connect to the batteries via the RS485 port and will visually display all key battery parameters to the user.
The display will also have an embedded audible alarm, that will be triggered in the event of a fault/alarm condition. This can be also used to comply with the new marine AS/NZS 3004.2:2014 standard for Lithium-Ion batteries.
Long Life & Warranty
The cell cycle life has been enhanced by newer prismatic cell designs and improved cell management by the new BMS to maximise battery life. Depending on the model, these batteries offer a very long cycle life of between 4000 to 6000 cycles at 100% Depth of Discharge.
The BluEdge series is backed by an Australian based 5-year warranty.
Robust Tough Design
Enhanced shock and vibration protection is provided via enhanced framing around the cell packs to prevent internal movement of the cells and/or electronics that may result in failures or metal fatigue over time. This makes these models very suitable for applications in rough offroad conditions, marine environments, and industrial applications where a robust construction is required. Amptron takes steps to ensure that all internal wiring is protected, and high-quality internal connectors and bus bars are used so intermittent failure modes are not introduced in harsh environments.
Uncompromised Waterproofing
Amptron has designed a unique triple-layered moisture protection on all models with ABS cases. The triple-layered design provides three barriers against potential moisture ingress:
- A method to inject the sealing adhesives in all seams to minimise the probability of small gaps/air pockets that may allow some moisture or moist air entering the battery case.
- A second sealed layer is installed inside the battery case above the cells and electronics. Should any moisture find a way to penetrate the seams of the outer casing, then this sealed layer provides a second barrier to prevent moisture reaching the cells and electronics.
- Additionally, the whole cell pack and electronics are wrapped in a sealed membrane. Even if any moisture finds a way to penetrate the above two barriers, or if any condensation should form internally in the battery case, then the membrane would protect moisture getting in contact with the cells or electronics.

Use Cases
The Amptron® BluEdge 12V 105Ah Blade Battery was designed for one specific problem: installations where standard battery height — even the Slimline — is still too tall. Its revolutionary 60mm profile opens up an entirely new class of fitment opportunities.
1. Under-Floor Caravan & RV Battery Trays
Most Australian caravans come pre-fitted with AGM battery trays under the chassis floor. The Blade drops straight in.
-
Zero-Modification Install: The Blade's footprint mirrors standard deep-cycle AGM batteries, meaning your existing tray, holddown brackets, and wiring need no changes — just swap and connect.
-
Weight Reduction: At 14kg versus 28–32kg for an equivalent AGM, the Blade significantly reduces chassis stress and improves tow vehicle fuel economy on long hauls.
-
AS/NZS 3001.2:2022 Compliant: Fully legal for Australian caravan electrical installations — no need to modify your compliance plate.
2. 4x4 Under-Seat & Flat-Floor Canopy Installs
Perfect for dual-cab utes with under-seat storage or sliding canopy floors where vertical clearance is under 70mm.
-
Fits Where No Other Lithium Fits: A 60mm-height restriction rules out virtually every other 100Ah+ lithium battery on the market. The Blade is the exception.
-
Horizontal Mounting Flexibility: Designed to lie flat — ideal for tray-style installations where the battery sits beneath a drawer system.
-
Smart Charging via DCDC: Full CANbus compatibility with DC-DC chargers allows intelligent split-charging without the complexity of manual battery settings.
3. Marine Under-Sole & Bilge Compartments
Many trailer boats and small cruisers have shallow bilge or under-sole compartments that are only accessible to flat-profile batteries.
-
Corrosion-Resistant Aluminium-Style Design: The conformally coated electronics protect against bilge humidity and condensation in these low-ventilation spaces.
-
All-Day Accessory Power: 105Ah is sufficient to power sonar, chart plotter, VHF, nav lights, and a live bait system for a full day's fishing.
-
AS/NZS 3004.2:2014 Compliant: Add the optional RS485 display for full marine audible alarm compliance.
4. Solar Storage in Tight Off-Grid Enclosures
For compact off-grid enclosures in remote cabins, sheds, or telecommunications huts where rack space is at a premium.
-
Horizontal Stacking: Multiple Blade batteries can be mounted horizontally in shallow enclosures, building 200–300Ah banks in spaces too tight for standard batteries.
-
Bluetooth Remote Health Check: Monitor each battery's SOC and cell voltages remotely without opening the enclosure.
-
4000+ Cycles in Testing: Long service life significantly reduces the cost and logistics of battery replacement in remote, hard-to-access installations.
5. Mobility & Medical Equipment
Electric wheelchairs, powered scooters, and mobile medical platforms often have fixed battery cavities sized for specific AGM profiles.
-
Like-for-Like Replacement: Replaces existing AGM cells in mobility scooters and power chairs that share the standard battery tray footprint, doubling or tripling range.
-
Vibration Tolerance: The reinforced internal cell framing handles the constant vibration of powered mobility devices, rough footpaths, and indoor obstacles.
-
Zero Maintenance: No electrolyte top-ups, no acid corrosion, no terminal cleaning — a critical advantage in medical and mobility contexts.
