 GiB Series Lithium battery, as critical part of the most popular Energy Storage System (ESS), is widely used in industrial & commercial applications as well as household solar systems. 

 

Super-safe lithium battery (lithium ion NCM or lithium iron phosphate LiFePO4) chemistry reduces the risk of explosion or combustion from high impact, over-charging or short circuit Battery Management System (BMS) controls the battery parameters to provide optimum safety, by protecting against over-charge and over-discharge. Intelligent BMS design balances the battery cells to an optimized performance.Higher-Capacity or Higher-Voltage available through parallel or serial connections. Robust ABS case with rugged-impact resistant.

Cycle life
GiB Lithium batteries are for customized projects, available with below DOD cycles, subject to the project budget.


DOD80% = 2000 cycles
DOD80% = 3000 cycles
DOD80% = 4000 cycles
DOD80% = 6000 cycles


Safety/Fuse Protection.
Under the protection of built-in BMS, every single piece of GiB Lithium battery is extremely safe with current control. The smart BMS would protect your batteries from over-load discharge, over-charge, temperature exceed (low & high safety level).

Equalization of battery initial specification.
We could have equalized specifications of the batteries in series/parallel on OCV, IR, Capacity, Temp, etc...

Warming / heating panel available for low temperature application (-45ºC).

This is quite helpful when batteries are used in extreme temperature conditions, summer hot and winter cold.

Customized with digital display screen, Bluetooth, GPS, etc... more functional configurations could be developed.
 

Tell us your power requirement, we could design/customize the battery system for you.

Company Profile

 

Preface

Electric power shall be available for everyone and everywhere, at an affordable and reasonable price. We don't generate the electric power - we do the storage, and dedicated to providing efficient, safe and stable battery power supply to every need.

 

Profile

Building on 21 years of foundational battery manufacturing expertise since 2004, Grand Energy Manufacturing Co Ltd (known as GEMFG) has strategically evolved from lead-acid production into a specialized lithium battery pack innovator. Our journey began with establishing robust lead-acid systems at our Quanzhou facility, cultivating deep insights into power solution reliability. Recognizing the energy transition, we founded GRAND ENERGY TECH (XIAMEN) CO LTD (known as GET)  in 2016 as a dedicated R&D engine to master lithium chemistry, cell integration, and safety architectures. This research excellence paved the way for our 2021 joint venture with Guangdong Tiequan New Energy Technology Co., Ltd., launching purpose-built lithium manufacturing under the GEMFG brand in Dongguan. Today, this 3,500m² ISO-certified hub consolidates our lithium operations, where 50+ engineers transform 21 years of electro-mechanical proficiency into industry-leading battery packs.

Monthly producing 45 MWh (equivalent to 15×40' FCL containers), we implement maturity-proven processes: From cell validation to proprietary BMS calibration, every step integrates ISO 9001/14001/45001, UN38.3, and CE-certified quality protocols. Our packs deliver uncompromising cycle life and safety-not through experimentation, but through hard-won manufacturing discipline refined over two decades. For global partners seeking lithium solutions where reliability transcends specifications, GEMFG stands as your experience-guaranteed source.
