BDSv5 SMART
The BDSv5 SMART is the next generaon of the Remote Audio BDS, the
standard in power management systems for ENG audio bags. It is a 12V
nominal compact DC power distribuon system that now features dual
power inputs that allow for baery hot swapping as well as input priority
and load sharing for higher current draw condions. It incorporates
System Management Bus (SMBus) communicaons and a built in 0.95”
color OLED display for detailed usage and runme stascs when using
smart baeries equipped with internal Baery Management Systems
(BMS) such as Remote Audio’s HI-Q 49Wh and 98Wh baeries.
Addionally, the BDSv5 SMART has been expanded from 6 to 8 outputs
and is available with 2 output connector variants: Standard (5.5mm barrel jack) and Hirose (4-pin).
Inputs: The BDSv5 SMART’s dual TA4-pin inputs can accept various types of baeries and DC input sources ranging from
9-18 Volts DC. The dual inputs feature an integrated power path controller meaning you no longer need to shut down
crical gear when it comes me to change out a depleted baery pack. Simply remove one of the baeries from its
corresponding baery cup and pop in a fresh one while the other baery will maintain an uninterrupted* output. The
power path’s interconnected ideal diode controllers prevent reverse current ow from one baery into the other.
*The total load on the BDS must be less than a single baery’s rated max discharge current to perform hot swaps.
Priority Input: A new feature to the BDSv5 is input priority. When enabled in the sengs menu, the BDS will priorize
drawing power from Input #1 while Input #2 goes into standby. This allows you to priorize using say an AC to 12V DC
adapted power supply plugged into Input #1 while conserving a 14.4V smart
baery plugged into input #2. If the voltage of Input #1 falls below a threshold,
the BDSv5 will automacally failover to the second input for uninterrupted
power output. Once power is restored to Input #1, it resumes its priority role for
powering the load and Input #2 will go back into standby. It should be noted that
a baery in standby will sll have a very small current draw on it from the
baery communicaons and microprocessor of the BDSv5 so it is normal to see a
baery in standby discharge slowly over me.
Load Sharing: Another new feature of the BDSv5 is a load sharing funcon
between two baeries whereby you can power loads that draw more current than a single baery pack is capable of
supplying by itself. For example, two HI-Q 49Wh, 3.4Ah baeries could supply up to 6.8Amps when load sharing, and two
HI-Q 98Wh, 6.8Ah baeries could supply up to the BDS’s limit of 12 Amps total current when load sharing. To enable load
sharing, you must turn o the Priority #1 seng in the sengs menu. For best performance when load sharing, it is
recommended to always use two baeries of equal capacity and similar states of charge. These features greatly expand
the BDSv5’s useability from ENG bags of all sizes to small and even mid-sized cart systems.
Output Current Limit: Since the BDSv5 can accept mulple baery capacies and DC sources, the BDSv5 Smart employs
a dynamic current limit and warning system. The maximum total load current handling of the BDSv5 is 12 Amps.
However, depending on what the input source type is or whether you have just one input acve, a lower current
limitaon and warning could be imposed. By default, any non-smart baery or DC input source is limited to 6 Amps (per
TA-4 input). Smart baeries capable of BMS communicaons will be limited to a 1C maximum discharge rate for safety.
1C is a rate of 1 mes the baery’s capacity so for a 49Wh baery with a capacity of 3.4 Amp hours, it would be limited
