Why 
Battery Systems designs and builds modular lithium-ion packs in the U.S. Our MonoLith™ and Lithium Block™ platforms accelerate integration, simplify compliance, and keep your team moving from first article to scaled production.
U.S.-Engineered & Assembled
Colorado-based builds with tighter comms and simpler logistics. Limited intake so work stays focused.
Platform Architecture
Shared subcomponents across packs to cut risk, shorten NPI, and keep spares/BOMs sane.
Safety Architecture Built-In
Dual HV contactors w/ pre-charge and controlled bleed; coordinated fusing (string → pack); cont. isolation monitoring; creepage/clearance designed for the target voltage and environment.
Documentation & Traceability
Build record, serials, acceptance checks, wiring pinout, and message map included with shipment.
Integration-Ready Interfaces
CAN 2.0B / J1939 with documented IDs/update rates, heartbeat & fault frames, discrete interlocks/hard-disable, charge enable, HVBD face-plate disconnect, internal HV fuse, harness pinout, mechanical envelope & mounting.
OEM & Fleet Focused
We specialize in low-to-medium volume OEM and fleet programs where there's a path to repeatable builds. Unlike large pack integrators who often won't engage until you're at very high volumes, we're willing to support smaller OEM programs and early-stage platforms, provided there's a real path to production, not one-off personal projects.
PackForge™
MonoLith™ Configuration Explorer
Upload a datasheet and let AI extract your specs, or drag the sliders to narrow your search across MonoLith™ battery configurations.
Upload a requirements datasheet or enter specs — our AI scores every configuration against your requirements and surfaces the top matches.
Sustained — power you draw continuously until the pack is empty.
Burst — highest power drawn in short excursions of about 2 minutes, followed by a return to sustained draw. Reaches roughly 46% of rated capacity before the cells terminate.
