About Us

G4 Synergetics, Inc. (G4) is a developer of clean, ultra-high power bi-directional batteries. G4’s advanced nickel metal hydride (NiMH) design is primarily for power-dependent applications, rather than high energy as most commercial cells are designed. G4 batteries have a low internal resistance which enables the batteries to deliver extremely high power. G4 Synergetic’s reduced internal resistance translates into less heat generation during charge and discharge. The design allows G4 batteries to be charged quicker (5 minutes) than conventional battery constructions.  

The cells are modular and batteries can be configured placing cells in series via stacking arrangements to provide the desired battery operating voltage with minimal resistance increase. Due to the modular nature of our design, stack size can vary to produce batteries with voltages ranging from 1.2V to 24V per module (nominal at C-rate).

G4 is a total solution provider as it provides both the battery and an integrated battery management system (BMS) for all applications. The battery management system regulates all aspects of battery charging and discharging to ensure that the battery operates both safely and efficiently.  There are redundant mechanical and sensing mechanisms built into the module design to mitigate thermal runaway or overpressure risk during overcharge/overdischarge.

With this proprietary technology, proven market acceptance, independent laboratory confirmation testing and production scalability, G4 Synergetics is uniquely positioned to help solve the challenges and opportunities of thermal management in high power battery applications.
