Powering Defense Innovation: How Lithium Battery Company’s 48V 100Ah LiFePO4 Batteries Enabled the Success of General Dynamics’ MUTT Project

Military technology is evolving rapidly. American manufacturers must collaborate to maintain our nation’s defense capabilities. One partnership exemplifies this innovation perfectly.

Lithium Battery Company partnered with General Dynamics Land Systems on the groundbreaking MUTT project. Our Tampa facility provided the advanced 48V 100Ah LiFePO4 batteries. These batteries became the power source behind one of the most significant unmanned ground vehicle programs in recent military history.

This customer success story showcases American manufacturing excellence. Moreover, it demonstrates how innovative battery technology supports critical defense missions.

The Challenge: Meeting Military Power Demands

General Dynamics Land Systems faced a complex challenge. They needed to develop the MUTT system for the U.S. Army’s S-MET program. However, this required more than just engineering excellence.

The project demanded a reliable, American-made power solution. Furthermore, it had to meet the rigorous demands of military operations [1]. The MUTT serves as a semi-autonomous robotic platform. Its primary purpose is reducing the physical burden on dismounted soldiers.

The battery system requirements were demanding. It needed consistent performance in harsh environments. Additionally, it had to maintain the reliability standards our armed forces expect.

Technical Specifications Required

The specifications were challenging. The system needed to power an 8×8 wheeled configuration. This configuration carries 1,200 pounds of payload across varied terrain. Export power capabilities reach up to 3kW. Operational ranges extend to 58 kilometers [2].

Traditional battery solutions couldn’t meet these requirements. Weight constraints presented additional challenges. Safety standards for military applications were non-negotiable.

Our Solution Approach

Lithium Battery Company’s expertise became invaluable. Our defense-grade lithium battery manufacturing capabilities were perfect for this challenge. Our Tampa-based facility specializes in high-stakes defense applications.

We developed specialized 48V 100Ah LiFePO4 battery packs. These became the heart of the MUTT system. Our unique position enabled us to deliver exactly what General Dynamics needed.

Understanding the MUTT: Revolutionary Military Technology

The Multi-Utility Tactical Transport represents a significant leap forward. Military robotics technology has never seen anything quite like it. The U.S. Army selected it in July 2020 for the S-MET program.

The contract was worth $162.4 million for 624 units. The MUTT has proven itself as “the most intuitive, capable and reliable UGV ever produced.” It’s also “the first of its kind to be selected for service alongside dismounted troops” [3].

Design Philosophy and Capabilities

The MUTT’s design centers on reducing soldier burden. Simultaneously, it enhances mission capabilities. Multiple configurations are available. These include 4×4, 6×6, and 8×8 variants.

The system operates in two modes. Semi-autonomous mode provides advanced functionality. Tele-operation mode offers direct control. Unique control methods include dismount following tether. Easy-to-use one-handed RC controllers are also available [4].

These features minimize soldiers’ physical loads. They also reduce cognitive loads during missions. This advantage is critical in modern warfare scenarios.

Technical Specifications

The 8×8 configuration became our collaboration focus. It measures 116 inches in length. Width reaches 70 inches. Gross vehicle weight totals 3,500 pounds.

Payload capacity is impressive. It carries 1,200 pounds while maintaining mobility. This works across diverse terrain. The capability makes it invaluable for military operations.

The system’s modular design allows various mission payloads. Future capabilities are planned. These include autonomous resupply and counter-unmanned aerial systems (C-UAS). Chemical, biological, radiological and nuclear (CBRN) defense is included. Intelligence, surveillance and reconnaissance (ISR) capabilities are planned. Electronic warfare (EW) and both direct and indirect fire capabilities will be added [5].

The Power Solution: 48V 100Ah LiFePO4 Technology

Our advanced 48V 100Ah LiFePO4 battery technology powers the MUTT’s success. This chemistry choice wasn’t arbitrary. LiFePO4 batteries offer considerable advantages for military applications.

High-power capabilities are a key benefit. Advantageous safety characteristics are another. Exceptional cycle life rounds out the advantages [6]. These attributes make them ideal for unmanned ground vehicles. Combat environments demand this level of performance.

Energy Storage and Performance

Our 48V 100Ah LiFePO4 battery packs deliver impressive capacity. Energy storage reaches 4.8 kWh. This provides the MUTT with necessary endurance for extended missions.

The 48-volt architecture was specifically chosen. It optimizes the balance between power delivery and system efficiency. The MUTT generates its required 3kW of export power. Operational ranges meet military specifications [7].

Safety Characteristics

LiFePO4 chemistry safety characteristics proved crucial. Unlike other lithium-ion chemistries, LiFePO4 batteries demonstrate exceptional thermal stability. They’re inherently resistant to thermal runaway.

This makes them significantly safer for military applications. Reliability under extreme conditions is paramount [8]. Their safety profile is excellent. They deliver consistent performance across wide temperature ranges. This made our LiFePO4 batteries the ideal choice for the MUTT program.

Our Manufacturing Role: From Concept to Deployment

Our collaboration with General Dynamics exemplifies comprehensive defense manufacturing. We took the project from initial research and development through full-scale deployment. This end-to-end capability operates from our Tampa facility.
