Audioroot eSMART ABE Active Battery Eliminator

Share

The Audioroot ABE is a small format battery eliminator which can be used to power smart battery-operated devices with an alternative DC source such as an AC/DC power supply, wall adapter or even another battery. A smart battery can also be connected to the ABE's power input connector to allow use of larger smart batteries to power devices that normally accept only small format batteries such as the Li-48neo or Li-49Wh.

Wiring of the TA4M input connector:

Pin 1: (-)
Pin 2: SMBus data*
Pin 3: SMBus clock*
Pin 4: (+)
_{*Wiring of pins 2 and 3 is not mandatory}

The ABE includes a smart battery emulation circuit to allow display of some information on Audioroot's smart current distributors when a simple DC power supply is connected to the ABE (i.e. pins 2 and 3 left unconnected). The ABE's smart battery emulator is compatible with the following devices:

• eSMART BG-DH MKII
• eSMART BG-DU
• eSMART BG-DU-REG
• eSMART K-ART

The following information are available when using the devices listed above with the ABE when smart battery emulation is active:

• Voltage
• Current
• Power
• Temperature

In this configuration (external DC power source and smart battery emulation ON), other values such as cycle count, capacity, and runtime are displayed with arbitrary values.

When should I enable the ABE’s internal smart battery emulator?

The switch enabling the ABE's internal smart battery emulator whould be set to ON when using the ABE to power a eSMART BG-DH MKII, BG-DU, BG-DU-REG or K-ART from a DC power source. The ABE's internal smart battery emulator should be set to OFF when a SMBus compatible battery is connected to the ABE's TA4M input connector using a 4 conductor cable (power + clock/data signals).
