Defense programs need a pack that does exactly what the specification says, every lot, with the documentation to prove it. We design around your equipment, environment and test plan, then hold the design under change control through production.
Catalog reference designs start at 10 units and custom programs at 25 units.
Typical defense equipment
- Ground vehicles and vehicle-mounted subsystems
- Portable and soldier-carried electronics
- Tactical communications and radio equipment
- Unmanned systems: ground robots and UAVs (UAV battery design)
- Sensors, surveillance and field power systems
- Test, training and support equipment
Defense battery pack requirements we work to
- Electrical: voltage window, continuous and pulse current, runtime, and fault behavior defined against your load profile.
- Environmental: temperature extremes, shock, vibration, altitude, humidity and ingress. Programs often call out environmental test methods; we design to the methods and levels your program specifies and scope testing for the program. Catalog designs are not qualified to environmental as listed.
- Mechanical: ruggedized enclosures, sealed connectors, mounting and handling for the platform.
- BMS and communications: SMBus, CAN or a custom interface, state-of-charge reporting, and fault and safety logic agreed with your systems team.
- Documentation and traceability: drawings, bill of materials, BMS settings, test records and lot traceability, with documented change control.
- Supply continuity: a frozen design, qualified component alternates where possible, and support for long program lives. See battery supplier replacement if an incumbent source is failing.
Sourcing and compliance clauses vary by contract. Send the clauses that apply and we'll review what the program requires before quoting.
Chemistry for defense equipment
NMC packs give the most energy per pound for portable and soldier-carried equipment. LFP packs suit vehicle and stationary systems where thermal stability and service life lead. Compare LFP and NMC.
How a defense battery program works
- Requirements and clause review: equipment, load profile, environment, interfaces and the contract clauses that apply.
- Design and prototype: cells, BMS, enclosure and wiring, with prototypes for fit and function.
- Qualification support: testing to the methods your program calls out, plus the documentation package.
- Pilot and production: first articles, a pilot lot, then volume under frozen design and change control.
Lead times run from weeks to months depending on cells, design scope and qualification; your quote confirms them.
What to send
Platform and equipment, voltage window, continuous and pulse current, runtime, envelope and connector, communications, environmental requirements and test methods, applicable contract clauses, first-article and annual quantities. Request a defense battery program review.

Defense battery pack FAQ
Do you build custom battery packs for military and defense equipment?
Yes. We design and build custom lithium packs for defense contractors and government equipment OEMs, from portable NMC packs to rugged LFP vehicle packs. Custom programs start at 25 units.
What should I send for a defense battery pack quote?
Send the equipment application, voltage window, continuous and peak current, runtime, available space, connectors, communications, environment, first-order quantity and annual volume.
Can a defense battery pack fit our enclosure and connectors?
Custom pack dimensions, enclosures, connectors and mounting are designed around the equipment requirements. Send drawings and interface details with your project inquiry.
Which chemistry is better for defense equipment?
NMC usually suits portable and soldier-carried equipment where weight matters most. LFP suits vehicle and stationary systems where thermal stability and service life lead.
What is the minimum order and lead time?
Catalog reference designs start at 10 units and custom programs at 25. Lead times run from weeks to months; your quote confirms them.
Can a defense battery pack report state of charge to our equipment?
The BMS can be specified with SMBus, CAN or a custom interface for state-of-charge reporting and fault information. The interface is defined with your systems team.
