Description

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 maximizes 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 any application requiring durable, high quality, dependable and lightweight Lithium Batteries.​

  1. 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.
  2. CELL BALANCING
    The BPS 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.
  3. T​HERMAL 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.
  4. SAFETY VENT
    High pressure safety vent
    Each cell has a high pressure safety vent that will flip open to release energy and prevent explosion.
  5. ELECTROLYTE
    Flame Retardant Electrolyte
    Our cells are manufactured with our patented flame retardant additive in our electrolyte.
  6. EXPLOSION PROOF
    Explosion proof Nickel plated steel
    Every AMPTRON® cell is manufactured in our Nickel plated steel case.
