On-line ordering, panic buying, and vaccine distribution are all increasing the need for cold-chain technology. Temperature-controlled supply chain is more important than ever during the Covid-19 pandemic. SAFEFlex enables 100% uptime and utilization of material handling equipment in cold storage and sub-zero environments. SAFEFlex is a drop-in replacement lithium-ion battery for lead acid battery power for electric material handling equipment. Click here to download our free whitepaper titled โBest Practices for Using Lithium-Ion in Cold Storage Facilitiesโ.
SAFEFlex provides material handling equipment crucial benefits, including:
There is no cold-temperature capacity loss with integrated battery heaters.
One-hour fast charging is enabled within the cold storage area (to -40 degrees).
Forklifts will never leave the freezer, and palletjacks can be charged in refrigerated trailers, so risksfrom condensation are minimized.
A permanently installed battery can support 24/7 continuous operation with an opportunity charging regime.
Maintenance is minimal, unlike lead acid batteries.
Cycle-life enables a useful product life of up to ten years
SAFEFlex batteries increase the velocity of distribution businesses with existing fleets of MH equipment including Walkie Pallet Jacks, End Riders, Narrow Aisle Forklifts, 3-4 Wheel Counterbalance Trucks, large Turrets, and other equipment. When compared to traditional lead-acid batteries, lithium batteries charge faster, last longer, and deliver more usable energy with each discharge. Batteries donโt need to be swapped, watered, or equalized at room temperature, streamlining operations and increasing efficiency at cold storage facilities.

Designers Can Easily Combine Bravo ECI or TSI Modular Inverter Systems with
Green Cubeโs DC Power Systems for Complete AC and DC Power Solutions
July 14, 2020 (Coral Springs, FL) โ Green Cubes (formerly branded as UNIPOWER) LLC, a world-leading supplier of industrial AC and DC power systems, announces its new family of Bravo modular inverter systems that provide customers with a highly efficient and modular AC or DC power solution. The Bravo inverters offer a modular and fully scalable solution using hot-swap inverter modules at 2.5kVA 120VAC or 3kVA 230VAC.
The Bravo ECI and TSI models are compact 2U (3.5 inch-high) rackmount inverters that can be configured with up to four 2.5kVA modules totaling 10kVA in a single 2U shelf. Units can be connected in parallel to increase the overall output of the inverter system and the hot-swappable modules can also be configured with N+1 redundancy. Moreover, the Bravo models provide extra AC input to ensure a high overall efficiency that results in a reduction of energy loss and heat dissipation.
โOur new Bravo ECI and TSI inverters offer a high level of modularity, reliability, efficiency, compactness and cost savings which perfectly align with our product commitment to our customers,โ said John Ely, vice president of marketing for Green Cubes. โWeโre very pleased to offer the Bravo line that provides a flexible and scalable power solution for a variety of telecom, utility and industrial applications.โ
Both Bravo inverter models convert 48VDC into a pure sine wave with an output of 120VAC or 230VAC. Outputs can be configured to deliver single-, dual- or three-phase AC power. The Bravo ECI technology eliminates all single points of failure with full scalability up to 32 modules in parallel and high efficiency of up to 96 percent in AC/AC conversion and above 93.5 percent in DC/AC conversion to minimize operating costs. Multiple Bravo ECI systems can be paralleled to reach up to 96kVA. The Bravo TSI models can scale from 2.5kVA up to 80kVA with a minimum of three rack shelves required for three-phase operation. Designed for easy configuration, the modules mount four at a time into a 19โณ rackmount power shelf along with a management module.ย Multiple shelves can be connected in parallel and can be wired for single-phase or 3-phase operation.
For enhanced system communications, Green Cubes offers an industry-first โtranslatorโ interface PCB that allows the inverters to seamlessly communicate with the existing Green Cubes ACX controller through the PowComโข network software. PowCom allows system communication through a local or remote PC and will automatically adjust its interface to the capabilities of the connected system – eliminating the need for two separate protocols.
The Bravo ECI and TSI inverters are available now.

Green Cubes is a great company, great engineers, great product. Thatโs been kind of my number one go to [lithium] battery.
President, Industrial Power Company
The thing I like about Green Cubes is that they have other lines of business outside of material handling batteries, they have been in the lithium world for a long time. I can trust they will likely stay in business
VP, Industrial Battery Company
Green Cubes [differentiates] on its capability to custom design for things like the hardware, the firmware, and inverters. They also have economies of scale because they make battery systems for things like forklifts.
VP, Powered Cart OEM
I am doing some work with them right now. Weโre learning their products, and looking at demos. They have good people. They seem like they know the technology well โ they say theyโre a technology company. I like that theyโve been in the lithium business a long time. I can trust they will likely stay in business.
Sales Manager, Industrial Battery Company
Green Cubes Technology would be my go-to for lithium applications.
Branch Manager, OEM
Iโve told my friends at Green Cubes, I donโt plan on going anywhere. I believe in loyalty.
