U.S.-Engineered Battery Systems. Built to Spec.
Custom lithium-ion battery systems engineered and assembled at a single facility in Boulder, Colorado, USA. Modular platforms from 3.6 V nominal to 1,000 Vdc maximum system voltage.
Government & Contract Credentials
Company Overview
EVolve Battery Systems (EBS) designs and manufactures lithium-ion battery packs and modules for aerospace, defense, marine, industrial, and robotics programs. All engineering and assembly is performed in-house at one facility in Boulder, Colorado, with no offshore subcontracting of core manufacturing. Founded in 2013, the company supports programs from single evaluation units through low-to-medium-volume production, with a minimum order quantity of 1.
EBS operates two product platforms — MonoLith™ turnkey systems and Lithium Block™ wire-bonded modules — plus a bespoke engineering service for requirements outside the standard catalog. Standard MonoLith configurations ship in 8–14 weeks ARO; custom builds run 14–18 weeks depending on scope.

End-to-end battery system engineering — from cell selection through certified, documented hardware delivery.
Wire-Bonded Cell Interconnection
Wire-bonded cell interconnection in 18650 and 21700 cylindrical formats, providing per-cell fusing at the bond and eliminating spot-weld nickel strip failure modes.
High-Voltage System Architecture to 1,000 Vdc
Dual main contactors with precharge and controlled bleed, HVIL interlock, continuous isolation monitoring, coordinated fusing from cell to string to main, and service disconnect.
Battery Management Systems
Digital BMS monitoring all cell voltages and system temperatures, VCU compatible; CAN 2.0B interface with documented message IDs, update rates, heartbeat, and fault frames, delivered with DBC file.
Thermal Management
Aluminum frame and heat-spreader baseline with forced-air, conduction-to-cold-plate, and liquid cold plate options sized to ambient, altitude, and duty cycle.
Electrical Interfaces
Amphenol SurLok Plus high-voltage connections and Deutsch DTM signal connectors as standard; alternate interfaces specified per program ICD.
Documentation & Traceability
Interface control document, dimensional STEP CAD, CAN DBC, serialized build records, acceptance test reports, and certificates of compliance delivered with every shipment.
Product Platforms
Configurable, qualified platforms that accelerate delivery timelines — not one-off custom builds from scratch.
Differentiators
Single-site U.S. manufacturing
Engineering and assembly under one roof in Boulder, CO — direct access to the engineers who design and build the hardware, with a proven operating history since 2013.
Prototype through production
MOQ of 1 for evaluation and development units, scaling to repeatable low-to-medium-volume OEM builds on the same validated platform.
Platform architecture
Shared subcomponents across the 622-pack catalog reduce NPI risk, shorten qualification, and keep spares and BOMs consistent across a fleet.
Complete data package
ICD, STEP CAD, CAN DBC, serialized build record, acceptance test report, and certificate of compliance ship with every unit — no black-box deliveries.
Compliance & Qualification
MonoLith cells and standalone Lithium Block modules are UN 38.3 certified, and all shipments include UN 38.3 hazmat documentation and compliant packaging via certified carriers. System-level qualification is scoped per program: EBS designs to and tests against customer-specified standards, delivering acceptance test procedures and reports under contract. A 1-year warranty on materials and workmanship applies, with extended terms available for production deployments.
