New Key Features

Data Recovery

Data Recovery Not Dependent on Battery Voltage. Our Interface Box contains a power injection feature to allow data download even with a completely dead battery. .


User Configurable Logging Intervals and Sleep Modes. The onboard 8MB of memory can be configured by the user to ensure optimal usage depending on how many hours the battery will be used in its application.  The user can also configure how the gauge goes into sleep mode so that memory is not needlessly used when the battery is not discharging.

Customized Battery Cables

Connection to the battery is accomplished by a cable from the Interface Box, and the cable can be customized to attach to the battery even while in the battery barrel.
