GEMFG 48V 150Ah Golf Cart Power Supply Battery 48V Lithium Battery
GiB Series Lithium battery, as a 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).

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.

Professionals
As a specialized lithium battery pack manufacturer serving diverse applications - Solar | UPS | Telecom | BESS | Motorcycle | High-Voltage Motive Power | E-Bike | Scooter | Forklift | Sweeper and industrial electric vehicles - GEMFG transforms premium lithium-ion cells into high-performance, safety-focused power solutions through advanced system integration. Our "Powered and Powerful" commitment drives a grounded quality ecosystem dedicated to pack-level excellence:
→ Cell Validation: Rigorous incoming checks via automated grading systems and real-world performance profiling ensure consistency in capacity, impedance, and thermal behavior.
→ Module Assembly: Automated laser welding with thermal monitoring guarantees robust electrical connections, while precision vision inspection verifies structural integrity and optimal cell spacing for thermal management.
→ Pack Integration: Proprietary BMS fine-tuned through exhaustive in-house testing delivers precise cell balancing and multi-tier protection against electrical faults.
→ Environmental Protection: All enclosures achieve IP21+ ratings validated through physical seal testing.
Leveraging proven automation (cell sorters, laser welders, aging equipment), we ensure manufacturing repeatability. Safety is proven through hands-on abuse testing: Vibration rigs simulate years of operational stress • Mechanical crush trials validate structural resilience • Controlled thermal propagation assessments confirm containment efficacy. Every batch undergoes real-world performance mapping - from sub-zero cold starts to high-temperature fast-charging - with full component traceability.
This practical approach delivers optimized energy density, extended cycle life, and failsafe operation across all applications, establishing GEMFG as your trusted partner where real-world reliability outweighs theoretical benchmarks.

FAQ
Q: Can we connect different lithium iron phosphate battery packs in parallel or series?
A: Yes. Customers can connect batteries in parallel or series. However, please note the following:
1. Before connecting in parallel, ensure that the voltage of each battery pack is the same. If the voltages are different, charge them at the same rate.
2. Do not connect discharged batteries in parallel with fresh batteries. This may reduce the capacity of the entire battery pack.
3. If you wish to connect batteries in series, please inform us of the target capacity of the entire battery pack. We will select the appropriate battery management system for each battery pack.
4. If you are not an expert in connecting batteries in parallel or series, please do not handle the batteries yourself. This may be dangerous and affect the battery cycle life.
Q: Can we connect different lithium iron phosphate battery packs in series?
A: You can purchase high-voltage batteries directly from us. We recommend not connecting batteries in series, as this will affect the cycle life of the battery pack.
Q: Do your battery packs include a battery management system? Can they be used in automotive applications?
A: Yes, our battery packs include a BMS. You can use them only for low-speed vehicles or as an auxiliary power source for standard vehicles. Do not use them directly for standard vehicles, as that would require a more complex BMS design.
