The Amptron® 12V 200Ah LiFePO4 battery is the high-capacity workhorse of the Classic Series, purpose-built for Australians who need serious stored energy without the complexity of a full smart-comms system. At 2,560Wh of fully usable power in a compact 370 x 192 x 245mm package weighing just 22kg, it replaces the old four-battery AGM bank that used to take up half your battery compartment and still ran flat by day two. The 200A continuous and 400A peak discharge handles large inverters, compressor fridges, electric winches, water pumps, and anchor windlasses without hesitation. Bluetooth connectivity gives you live state of charge, voltage, temperature, and cell health from your phone via the Amptron Link App, and the built-in BMS manages everything else automatically. Rated for 5,000+ cycles at 80% DoD and backed by Amptron's 4-year Australian warranty, this is the battery that serious off-gridders, caravan tourers, and marine operators have been building their systems around.

These batteries are designed using only the highest quality components and are backed with our 4-year warranty. This includes the use of a robust Battery Management System (BMS), Aluminium encased prismatic cells, solid busbar connectors and internal protection to reduce movement and damaging vibrations. Our batteries can also be placed on their sides providing versatile installation options.

The integrated Battery Management System is designed to monitor, protect, and optimise each cell within the battery. The BMS maximises the performance of the battery by automatically balancing the cells and protecting them from over charging, over discharging, over temperature, and excessive charge or discharge currents. Our integrated BMS allows our batteries to be used as an alternative replacement for most applications requiring deep cycle batteries, however if the charging system does not support a Lithium charge profile, there are some compromises – please contact Amptron for more information.

Features

Heavy Duty – Built In BMS (Battery Management System)

AMPTRON® Lithium batteries use a built-in Battery Management System (BMS) designed to automatically disconnect the charging or discharging circuits to prevent damage to the cells and internal electronics from abnormal operation and helps to ensure safe and accurate operation of the battery.

THE BMS PROTECTION FEATURES INCLUDE:

• 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 maximum voltage.
• Short Circuit and Over Current Protection Switch – Automatically disconnects the discharge circuit if the load draws currents above 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.

CELL BALANCING

The BMS balances the cells through top-end balancing and will discharge cells that exceed 3.65V during charging.

INTERNAL CELL SAFETY

THERMAL FUSE: Our latest prismatic cell technology is manufactured with an internal thermal safety fuse between the anode and cathode that will break and disconnect in the unlikely event the cell would begin to overheat.

SAFETY VENT: Each cell has a high-pressure safety vent that will flip open to release energy and prevent explosion.

FLAME RETARDANT ELECTROLYTE: Our cells are manufactured with a flame retardant additive in our electrolyte.
