Precision Lithium Battery Solutions for Aerospace, Defense and OEM ApplicationsAt CHARGEX®, we engineer high-performance lithium batteries and chargers designed to meet the most demanding requirements. For over 15 years, we offer both standard and fully customized solutions for industries including Marine, RV, Telecom, Industrial, Aerospace, and Defense. Trusted by global innovators like SPACEX, NASA, BOEING, JPL, and The U.S. Navy, come see how our batteries power the world’s most critical missions.
Bolted Construction for Unmatched Strength and PerformanceChargex® Lithium Iron Phosphate (LiFePO4) batteries are engineered for durability and performance using bolted 32700 stainless steel cylindrical cells—a significant advancement over conventional tab-welded designs.
Each cell is secured through a rigid Lengthway Circuit Board, adding structural integrity and enhancing electrical conductivity. To further reinforce the pack, we use heavy-duty solid copper bus plates that resist bending and warping—even under extreme conditions—ensuring maximum current flow and long-term reliability.
Engineered for Strength, Safety, and Reliability
The Chargex® Battery Management System (BMS) stands out with premium-grade MOSFETs and high-quality electrical components—delivering exceptional efficiency, performance, and long-term dependability. Our BMS modules support higher charge and discharge currents than many competitors, making them ideal for both deep cycle and engine-starting applications.
Every BMS includes built-in protections such as short circuit, reverse polarity, low voltage, and overvoltage safeguards. Unlike others, we typically exclude low-temperature shutdown features, giving you uninterrupted power in cold environments. While this may slightly reduce battery life, it ensures your Marine, RV, and electronic systems keep running when you need them most.
Lengthway Circuit Boards
Chargex® lithium batteries feature Lengthway Circuit Boards, which bolt each cell together—providing structural rigidity and seamless integration with the Battery Management System (BMS) for precise cell balancing.
In the rare event of a cell failure, the Lengthway Circuit Board isolates the affected cell, preventing a short circuit and allowing the rest of the battery to continue operating safely. In contrast, traditional tab-welded battery packs are built as a single string of cells—meaning one cell failure can cause total pack failure.
Key Advantages:
-
Strong, rigid battery pack design
Individual cell protection and isolation
-
Continuous operation even if a single cell fails
-
Superior to traditional tab-welded designs
32700 3.2V 6.3Ah LiFePO4 Lithium Iron Phosphate Battery Cell
Chargex® lithium Iron Phosphate Batteries are built using our 32700 – 3.2V LiFePO4 explosion-proof stainless steel cells. Each cell is bolted—not tab welded—for superior electrical conductivity and a more secure, long-lasting connection.
Designed with safety in mind, every cell features an integrated thermal fuse that automatically disconnects in the rare event of overheating. Combined with a high-pressure safety vent and flame-retardant electrolyte, this makes our battery cells among the safest in the world.
Key Features:
-
Explosion-Proof Stainless Steel Construction
-
Bolted Cell Design for Maximum Conductivity
-
Built-in Thermal Fuse for Overheat Protection
-
Flame-Retardant Electrolyte
-
High-Pressure Safety Vent
