AMPTRON® 12V 100Ah Lithium LiFePO4 Batteries are an alternative replacement (AR) for any application currently using a deep cycle Gel, AGM or Flooded Lead Acid battery. The maximum continuous discharge current is 175A and peak discharge current 320A for 3 seconds.





Our batteries come with a 4 year warranty and are designed using only the highest quality components. This includes the use of a robust Battery Protection System (BPS), aluminum encased prismatic cells, solid busbar connectors and a solid frame to reduce movement and damaging vibrations.  AMPTRON® batteries can also be placed on its sides without the risk of components coming loose or loss of usable capacity.

Our Lithium batteries use a high quality robust integrated Battery Protection System (BPS) and is designed to manage and control all the battery protection requirements. The BPS maximises the performance of the battery by automatically balancing the cells and protecting them from being over charged or over discharged. Our integrated BPS design is what allows our batteries to be used as an AR "Alternative Replacement" for many applications requiring durable, high quality, dependable and lightweight Lithium Batteries.​

Heavy Duty - Built in Battery Protection System


AMPTRON® lithium batteries have a built-in Battery Protection System (BPS) designed to prevent damage to the cells from almost any external accidental occurrence that would normally cause damage. The internal BPS will automatically disconnect to prevent damage to the cells if the battery drains below 10 volts. It will automatically reconnect when the charger is turned on. This protects the battery from over-discharging and damaging the cells. This technology also protects the battery from overcharge, short circuit and reverse polarity.


  • Low Voltage Protection Switch - Automatically disconnects around 10V
  • Over Voltage Protection Switch - Automatically disconnects around 14.8V
  • Short Circuit Protection Switch - Automatically disconnects
  • Reverse Polarity Protection Switch - Automatically disconnects
  • Internal cell balancing   - Automatically balances cells
  • Charge Balancing - Independent balancing for multiple batteries connected in parallel or in series.
  • This Battery Protection System is designed to last throughout the life of the battery and provide reliable power for thousands of cycles.

CELL BALANCING - The BMS balances the cells by sending more current through the length way circuit boards and into cells with a lower voltage. The BMS will also discharge cells that exceed 3.65V during charging. ​

THERMAL FUSE - Internal Cell Safety Fuse
Our latest cell technology is manufactured with a 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 - High pressure safety vent
Each cell has a high pressure safety vent that will flip open to release energy and prevent explosion.
ELECTROLYTE - Flame Retardant Electrolyte
Our cells are manufactured with our patented flame retardant additive in our electrolyte.
EXPLOSION PROOF - Explosion proof Nickel plated steel
Every AMPTRON® cell is manufactured in our explosion proof Nickel plated steel Prismatic case.

Are Lithium batteries safe?

Lithium Iron Phosphate (LiFePO4) batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The cathode material in LiFePO4 batteries is not hazardous, and so poses no negative health hazards or environmental hazards. Due to the oxygen being bonded tightly to the molecule, there is no danger of the battery erupting into flames like there is with Lithium-Ion. The chemistry is so stable that LiFePO4 batteries will accept a charge from a Lead Acid configured charger.


Can I use AMPTRON® LiFePO4 batteries as a replacement for Lead Acid batteries?

AMPTRON® Lithium LiFePO4 batteries are a Plug and Play replacement for any application currently using deep cycle Gel, AGM or Flooded Lead Acid batteries. Q> What is the life expectancy of a Lithium battery? The typical estimated life of the AMPTRON® Lithium Iron Phosphate (LiFePO4) battery is 5-15 years, or 2000 to 5000 charge cycles.


Do Lithium batteries have a memory?

Unlike NiCad batteries, Lithium LiFePO4 batteries do not have a charge memory. That means carefully controlled deep-discharge cycles are not required, and partial-discharge cycles has no negative effect on the batteries.


Why are Lithium Iron Phosphate LiFePO4 batteries better?

LiFePO4 (also known as Lithium Iron Phosphate) batteries are a huge improvement over Lead Acid batteries in weight, capacity and life cycles. The LiFePO4 batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The stability of the chemistry also gives these batteries exceptionally long life.

When should I charge my Lithium battery?

Lithium Iron Phosphate (LiFePO4) batteries can be left or cycled in a partially discharged state for long periods with few or no adverse effects, such as sulphation. AMPTRON® lithium batteries have a builtin Battery Protection System (BPS), that will automatically disconnect when the low voltage cut-off is reached, protecting the batteries from excessive discharge. These batteries also do not have a charge memory. All of this means that the batteries can be charged at any point. However, to maximize the battery life, it is recommended to recharge the batteries when they reach 20% State of Charge or higher.
