The AMPTRON? battery monitor is a high precision current type battery capacity meter (also known as a coulometer) designed to monitor the performance of battery systems. The unit continuously measures voltage, charge and discharge current, energy consumed and remaining battery capacity (State of Charge). This information leads to more efficient use of the battery system.

The product can monitor most battery types, include Lithium ion, Lithium Iron Phosphate, Lead Acid and Nickel-metal Hydride batteries with a working voltage from 8V to 80V.

The monitor can monitor large continuous current flows of up to 100A continuous, and up to 150A for 10s.

The combo system is easy to install DIY. The meter is suitable for use in mobile and portable powerpacks and equipment; cars; boats; recreational vehicles; Offroad and 4×4 vehicles; e-bikes etc.
