AMPTRON 12V 150Ah / 175A 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 10 seconds.
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.
Under normal usage where the DOD is <80%, cycle life is expected to be up to 5000 cycles

Connecting Terminals Pos (+) & Neg (-)
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
