THERMAL FUSE
Internal Cell Safety Fuse
Our cells have a built-in thermal safety fuse between the anode and cathode that will break in the unlikely event the cell overheats.
SAFETY VENT
High Pressure Safety Vent
A high pressure safety vent will flip open to release energy and prevent explosion if exposed to extreme heat.
ELECTROLYTE
Flame Retardant Electrolyte
Our cells are manufactured with a flame retardant additive in the electrolyte making them safe.
EXPLOSION PROOF
Explosion Proof Stainless Steel
Every Lithium Battery cell is manufactured in an explosion proof stainless steel cylindrical case.
"Enhanced Safety & Performance With Lengthway Circuit Boards
Chargex lithium battery cells are securely bolted together through printed circuit boards (PCB's), which are seamlessly integrated with our Battery Management System to ensure individual cell balancing. In the rare occurrence of a cell failure, these lengthwise circuit boards automatically isolate the problematic cell, preventing any potential short circuits and enabling the rest of the battery to operate flawlessly.
In contrast, many other manufacturers employ tab welding to connect cells. In such cases, if a single cell experiences a failure, it can lead to a catastrophic short circuit, ultimately resulting in the premature failure of the entire battery pack. "
"Engineered for Durability, Safety, and Reliability
At the Battery Management Systems lab here at Chargex, we take pride in our commitment to excellence. Our Battery Management Systems stand out thanks to utilizing top-tier MOSFETs and high-quality electrical components, ensuring maximum efficiency, peak performance, and reliability resulting in extended life cycles.
What sets our BMS modules apart is their superior charge and discharge current capabilities compared to competitor lithium batteries of the same capacity. This means you can rely on our batteries for a wide range of applications, from deep cycle to starting, with absolute confidence.
"instantaneous Safety Shutdown Procedures
Each Chargex BMS is outfitted with crucial safety functionalities, which operate autonomously to instantaneously disconnect the circuit under certain conditions such as over-voltage protection, low voltage protection, reverse polarity protection, and short circuit protection. These characteristics are instrumental in prolonging the battery pack's lifespan and safety of its operation. Top Tier MOSFET's utilized guarantee performance with higher current charge and discharge capabilities for applications with large continuous charge or discharge requirements such as bow thrusters in large yachts and EV applications.
"Top Tier Design Where Quality Matters
Chargex Lithium Batteries go far beyond the subpar lithium battery found on the worldwide web. Our bolted cell technology, top tier materials and electrical components bring our battery to a higher standard required for mission critical aerospace and defense applications.
When Quality Matters, There’s No Room for Compromise.
CHARGEX® 32700 3.2V 6.3AH Stainless Steel, Explosion-Proof LiFePO4 Cell
At CHARGEX®, our battery technology begins with the precision-engineered 32700 – 3.2V 6.3AH Lithium Iron Phosphate (LiFePO4) Stainless Steel Cell, designed for unmatched performance and reliability.
What truly distinguishes our cells is an unwavering focus on safety. Each cell is equipped with a built-in thermal fuse that automatically disconnects in the rare event of overheating—effectively isolating the issue and stopping it from escalating. In addition, a high-pressure safety vent and flame-retardant electrolyte work together to make these cells among the safest available anywhere in the world.
Thanks to recent innovations, we’ve boosted the cell’s capacity to an impressive 6.3AH while extending its lifespan to over 6,000 cycles—delivering lasting power you can count on.
Leading the Charge in Telecom Power Solutions
Chargex is rapidly becoming the go-to choice for telecom power across the U.S., as the industry moves away from outdated lead-acid technology. Traditional lead-acid batteries are inefficient, maintenance-heavy, and costly to replace—often falling short when it comes to performance and lifespan.
Our newly released line of telecom lithium batteries is changing the game. Designed to be a direct drop-in replacement for standard lead-acid batteries, these cutting-edge units fit seamlessly into existing telecom cabinets and infrastructure. No retrofitting required.
Built with advanced LiFePO4 technology, each battery delivers dramatically longer run times, virtually zero maintenance, and an extended lifespan—lasting thousands of cycles without performance degradation. This means cell towers stay online for hours longer during outages, reducing downtime, service interruptions, and costly field maintenance.
As the telecom industry shifts toward smarter, longer-lasting power solutions, Chargex is leading the way—one tower at a time.
Cylindrical CellsCylindrical cells are the most commonly used cell type today. The cylindrical design allows for better automation processes and techniques that increase consistency and lower cost.
