AEROSPACE
Chargex provides advanced lithium battery solutions engineered for satellites and aerospace applications, delivering high energy density, reliability, and custom configurations for mission-critical performance.
SPACE LAUNCH
Chargex develops lithium batteries for space launch systems built to withstand extreme forces, temperatures, and mission-critical demands from liftoff to orbit.
DEFENSE
Chargex builds lithium batteries for defense applications that deliver dependable power, durability, and consistent performance under the toughest conditions.
ENGINEERING EXCELLENCE
Advanced Technology
Precision-engineered battery systems built for extreme performance and reliability
Bolted Construction
Unmatched Strength and Performance
Chargex 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.
Advanced Battery Management
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 over voltage safeguards.

Ideal for deep cycle and engine-starting
Lengthway Circuit Boards
Individual Cell Protection and Isolation
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.
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 LiFePO4 Battery Cell
3.2V 6.3Ah Explosion-Proof Power
Chargex lithium Iron Phosphate Batteries are built using 32700 – 3.2V LiFePO4 explosion-proof stainless steel cells. Each cell is bolted, not tab welded, for superior electrical conductivity and a secure, long-lasting connection.
Designed with safety in mind, every cell includes a thermal fuse that disconnects during overheating. A high-pressure safety vent and flame-retardant electrolyte make these cells among the safest in the world.
ADVANCED PROTECTION
Multi-Layer Safety
Integrated Thermal Safety Fuse
Each cell features an internal thermal fuse positioned between the anode and cathode. In the rare event of overheating, the fuse automatically disconnects to prevent thermal runaway and ensure safe operation.
High-Pressure Safety Vent
Each cell features a high-pressure safety vent engineered to activate under extreme heat or pressure, safely releasing internal gas buildup to prevent rupture or explosion.
Flame-Retardant Electrolyte
Our cells are engineered with a flame-retardant additive integrated into the electrolyte, enhancing safety by minimizing the risk of combustion under extreme conditions.
Explosion-Proof Stainless Steel Housing
Each lithium battery cell is encased in a high-strength, explosion-proof stainless steel cylindrical housing, providing superior protection against external impacts and internal pressure buildup.
Designed to Replace Outdated Lead Acid, Gel, and AGM Batteries
Plug & Play
Drop-in replacement - same group sizes as standard lead acid batteries. Simply connect your battery cables and you're ready to go.
Modular
Connect multiple batteries in series and in parallel to increase voltage, power, and capacity.
Built-in Battery Protection
Every battery comes with a built-in battery protection system designed to protect and maintain the battery cells.
70% Lighter than Lead
Lithium Batteries average 70% lighter than the same size lead battery. Plus - our batteries don't contain toxic lead, gases, or acid.
100% Depth of Discharge (DOD)
CHARGEX® Lithium Ion Batteries can be discharged to 100% of the rated capacity.
Long Life 3000 - 5000 Cycles
CHARGEX® Lithium Batteries outperform our competitors in quality, safety, reliability, and life.
