48V 100Ah / 200A Continuous Discharge LiFePO4 Battery

AMPTRON® 48V 100Ah Lithium LiFePO4 Batteries are an alternative replacement (AR) for most applications currently using a deep cycle Gel, AGM or Flooded Lead Acid battery. The maximum continuous discharge current is 200A and peak discharge current 500A for 5 seconds.

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.

HEAVY DUTY – BUILT IN 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.
