Key Features
Benefits
Modular Design
1, 2, 3 & 4 x 48 V string configurations possible with up to
16 x 12 V monoblocs per cabinet.
Flexible sizing for different power and energy requirements.
Plug ‘n’ Play Solution
Available pre-installed or pre-wired for integration on-site,
depending on site accessibility.
Reduce onsite labour and accelerate installation time.
Small Footprint
Offering 20 kW power at the 1 hour discharge rate in a
1 m x 0.6 m footprint.
Passive Thermal Design
Maximizes battery life by channelling airflows to promote
operation within optimum temperature bands.
Indoor and outdoor version available.
UltraBattery Monitoring
A monitor on each UltraBattery provides access to State of
Charge and other vital information to assist with operating
the system within its optimal performance range.
Over-current Protection
Protect the system from excessive current and faults.
High power available in a small footprint means fewer
batteries, so space on site is optimised.
Maximizes your business case and return on investment
by reducing diverging effects of temperature on the
UltraBattery cells.
To suit different application scenarios and operating
environments – including indoor or outdoor installations.
Use monitoring data to manage the UltraBattery system
to achieve greatest longevity. Monitor each individual
monobloc remotely to diagnose issues before going to site.
Maximise the safety and longevity of your system with
application-specific rated breakers or switch fuses.
The breakers can also be tripped by the battery control
system to make sure the batteries are operated within
performance limits.

Behind the Scenes
UltraBattery® Technology in
Partial State of Charge Use
UltraBattery is a new dimension in lead-acid technology: a hybrid, long-life lead-acid energy
storage device containing both an ultracapacitor and a battery in a common electrolyte.

UltraBattery is a hybrid, long-life lead-acid energy storage device. It combines the fast
charging rates and longevity of an ultracapacitor technology with the energy storage
potential of a lead-acid battery technology in a hybrid device with a single common
electrolyte.
UltraBattery is highly efficient in a continuous partial state of charge (PSoC) operation:
neither totally full, nor totally empty.
UltraFlex with optional outdoor enclosure
Conventional valve-regulated lead-acid
(VRLA) batteries, when used for renewable
support, are typically operated in a top of
range cycling pattern and can prematurely
fail if operated in the PSoC range for
extended periods. UltraBattery® technology
was created to exploit the performance
benefits of the partial state of charge
(PSoC) band.
During lead-acid battery operation,
lead sulphate crystals grow on the
negative electrode during discharging
and fully dissolve at full charge. In PSoC
some crystals can become permanent,
increasing the battery’s internal resistance,
and decreasing its power, capacity and
efficiency. UltraBattery® chemistry inhibits
the sulfation allowing the battery to operate
with high efficiency in a PSoC.
The outcome: UltraBattery outperforms
and processes more energy in PSoC
applications.
UltraBattery is a new player in the leadacid family. Lead-acid batteries are
the world’s most ubiquitous chemical
storage chemistry, favoured for its reliable
performance in demanding conditions and
its ability to deliver high power and energy.
As the world’s most sustainable industry,
processes developed over the last century
support the closed loop recycling of old
batteries into new batteries.
Every UltraBattery is fully monitored with browser-based reporting
With UltraBattery, lead-acid becomes a
fully-monitored, fast-cycling, partial charge
technology suited to almost every any
energy-storage application.
