eSMART K-ART

Location sound cart dual battery power distribution system with universal fuel 
gauge

Version 1.2 Updated 14/10/2019

The 

AUDIOROOT eSMART K-ART

 is a low footprint power distribution box with a total of 

16 

direct DC power outputs

 and 

4 x USB 5V ground isolated outputs

. The K-ART includes 10 led 

illuminated pushbutton power switches, a main pushbutton power switch and 

2 battery fuel gauges

Like it’s little brother 

eSMART BG-DU

 the 

K-ART

 is fully compatible with 

any type of battery

 ranging 

from 9 to 18V. When used with our eSMART Li-xxWh or LiFe-xxxWh batteries the K-ART provides full 
battery informations without any calibration routine.

This product was designed for use on small to medium size 

location sound carts

. The power 

distributor can be connected to 2 batteries at once. The 2 batteries will discharge simultaneously thru an 
integrated ideal diode. These batteries can be of any type of chemistry

 

 (SLA, NI-MH or LI-ION) and the 2 

fuel gauges provide all the informations required to monitor the batteries state of charge (voltage, 
current, power, etc…).

The 

eSMART K-ART

 uses internal coulomb counters and a calibration routine to measure each 

battery’s true capacity and display it’s remaining capacity in real time. This power distributor is also fully 
compatible with our full line of smart batteries. When plugging an AUDIOROOT eSMART battery to the K-
ART the user will have access to all the battery’s information without the need to perform any type of 
calibration.

Key features :

10 switchable DC power paths

 via led illuminated push button switches (on/off state of each 

switch is stored and recalled automatically on each power up) 

1 main power

 illuminated push button switch 

12 x HRS 4

 DC power outputs (2 on the front, 10 on the rear of the unit, all Hirose outputs are 

switched on and off by pairs) 

4 x XLR 4

 DC power outputs (1 on the front, 3 on the rear of the unit). Each XLR 4 output has it’s 

own power switch 

4 ground isolated USB ports

 (allways on). 2 outputs are located on the front of the unit and 2 

outputs are located on the rear of the unit. The K-ART can source up to a total of 3Amps on the 4 
USB ports.

Real time SOC battery monitoring

  : remaining capacity (%), run time estimation, battery 

voltage, power consumption, power and coulomb counter 

Polyswitch 

2.5A

 resetable fuses on each 

output

 

Polyswitch 

8.0A

 resetable fuses on each 

battery input

 

blinking LED

 for each battery indicates when the battery capacity falls below 

10 %

 

Compatible with any battery ranging from 9 to 18V DC
