Lithium SAFEFlex Motive Chargers

The Lithium SafeFlex Battery Charger is designed to operate with Material Handling (MH) and Ground Support Equipment (GSE) Lithium-ion batteries. This charger has universal AC power input, supports full Level 3 charging via a CANBus communications with the battery, has a touchscreen display, provides unity power factor with very low iTHD which results in very high charging efficiency, and has the smallest footprint in the MH and GSE charger industry.

Rack-based Battery Charger

The Guardian and Aspiro product families of industrial energy management equipment provide highly configurable and modular stationary charging solutions for both traditional lead acid and lithium ion batteries. These power systems contain AC to DC rectification, sophisticated battery charging, low voltage disconnect, and DC power distribution in a single rack mounted solution. Available in sizes from 1RU to 10RU and capacities up to 1200A at 48V there is a system for every application. Typically deployed in Telecom, Data Center, and Edge Computing applications the Aspiro and Guardian power systems provide power management for multiple stationary applications.

Green Cubes also provides highly reliable ARE and ARM series of chargers for the utility backup battery market. These resilient and rugged chargers provide long lasting power for utility, grid, and critical infrastructure backup batteries. Configurable in both SCR and Ferro-Resonant technologies these chargers have a proven track record of success.

Custom Battery Chargers Engineered for OEMs

Green Cubes offers custom industrial battery chargers and docking stations for portable and handheld devices. As a complete power system solution provider, Green Cubes has the fundamental battery chemistry knowledge that is the keystone of industrial battery charger design. This allows Green Cubes to design and manufacture a charger that seamlessly integrates with the battery pack for exceptional ease of use and maximum energy delivery with a minimum charge time. Green Cubes maintains a catalogue of in-house reference designs for use in configuring individual battery charger solutions. Green Cubes’ high efficiency industrial chargers can be either a circuit board embedded in your device or a stand-alone charger in a configuration that best suits the usage model of the portable device. We also design and manufacture heavy duty industrial battery chargers to meet your most demanding needs.
The range of handheld devices supported by Green Cubes includes bar code scanners, handheld readers, portable printers, rugged PDAs, handheld computers, handheld radios, GPS devices and wearable computers.
In order for an user to take full advantage of a portable device, it must be charged quickly and remain in a high state of readiness. Multi-bay battery chargers are the best way to keep the most demanding users up and running through multiple shifts and our customer can optimize charge time according to the battery chemistry and the current available to the system. Green Cubes routinely designs chargers with the number of bays ranging from one to eight. Our multi-bay battery chargers employ our unique microcontroller-based charging system and are available with the following features:

Customer Ratings and Reviews

Green Cubes is a great company, great engineers, great product. That’s 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. We’re learning their products, and looking at demos. They have good people. They seem like they know the technology well – they say they’re a technology company. I like that they’ve 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

I’ve told my friends at Green Cubes, I don’t plan on going anywhere. I believe in loyalty.
