20kW Ecoult UltraFlex 48V Deka UltraBattery Energy Storage System
SKU Ecoult UltraFlex 4 x 48 V
Ecoult UltraFlex 48V Deka UltraBattery 20kW Energy Storage System
With 17 kWh of usable energy storage at 60% range of charge and 20 kW of peak power, the high‑cycling, energy-efficient Ecoult™ UltraFlex™ 48 V system is safe and simple to deploy, operate, and maintain using state-of-the-art Deka UltraBattery energy storage technology.
The Deka UltraBattery is a hybrid, long-life lead-acid energy storage device. It combines the fast charging rates of ultracapacitor technology with the energy storage potential of a lead-acid battery in a single hybrid device. The UltraBattery is used for partial-state-of-charge (PSoC) applications where batteries may need to charge and discharge rapidly and frequently.
Due to the UltraFlex system's high-power, high-cycling and high-energy capabilities, it is the plug ’n’ play energy storage device of choice for a range of applications and environments.
The UltraFlex Energy Storage System is used for:
- Residential battery backup energy shifting
- Small & medium commercial energy storage systems
- Distributed infrastructure
- Mobile telecoms
- Utility grid modernization
- Rugged & remote locations
Each Ecoult UltraFlex 48V System Includes:
- 16X Deka® UltraBattery® 12V monoblocs
w/ integrated monitors - System monitoring and control
- Over-current protection on each string

Ecoult UltraFlex 48 V UltraBattery Energy Storage System Review
UltraFlex UltraBattery System Applications
Flexible uses of the UltraFlex energy storage system include remote off-grid hybrid energy systems, telecom, microgrids, renewable energy smoothing and energy shifting for residential and commercial environments.
Renewables Integration
• Smoothing: Smoothing of renewable energy power sources
• Feed-in management and ramp-rate control: Distributed management of renewable energy sources feeding into the electricity grid
Diesel and Off-Grid
• Hybrid energy systems: Downsizing of diesel/fossil-fuel generators and reduction of generator use greatly lowers costs and fuel consumption reducing CO2 and other emissions
• Remote-area power supply: Reliable off-grid renewable power solutions
Energy Shifting/Cost Control
• Peak lopping/peak demand management: Shifting of energy availability to cover demand peaks
• Energy arbitrage: Storage of off-peak energy for use during peak charge times
Revenue Generation
• Frequency regulation: Provision of distributed grid ancillary services or demand response
