Audioroot 14.4V 48Wh smart lithium battery with embedded OLED display

This all new model has a built-in OLED display which allows real time display of the battery’s state of charge information. This helps users get precise information about a battery’s voltage, current draw, run time, etc… when connected to any type of equipment. This is very useful when connecting the battery to a piece of equipment or DC current distributor which is not SMBUS enabled.

Operation of the embedded OLED display is fully automatic. When the battery is disconnected the OLED can be activated by shaking the battery allowing to check battery capacity, cycle count and pack temperature. When powering a device from the battery the OLED display turns on and displays real time state of charge information. Once the device is shut down or disconnected from the pack the OLED display shuts off.

When the battery is connected to a fully compatible SMBUS device the OLED will stay to save power and keep the SMBUS lines free.

MAIN FEATURES :

High energy density rechargeable li-ion battery

SMBUS compatible Impedance Track™ fuel gauge

Embedded OLED display

Industry standard 5 pin connector
