Revolutionary Technology Platform
Our patented MonoLith™ platform represents a fundamental breakthrough in battery system architecture, delivering unprecedented scalability and cost efficiency for mission-critical applications.
Industry-First Patented Technology
Revolutionary modular architecture with proprietary scaling algorithms and thermal management systems.
Rapid Scalability Platform
Scale by 24-cell building blocks to the program's target energy. No redesign, no retooling, minimal lead time impact.
Minimal Tooling Investment
Standardized interfaces eliminate custom tooling costs. One platform serves multiple applications.
Accelerated Time-to-Market
Pre-validated modules and documented interfaces reduce integration time from months to weeks.
Who MonoLith Is For
MonoLith is designed for teams building repeatable products and platforms, not one-off personal projects.
Good Fit
- Commercial & OEM programs: emerging manufacturers, fleet operators, defense and robotics integrators, and advanced R&D teams
- Low-to-medium volume production: we specialize in OEM programs where you're building a repeatable product or vehicle platform, even starting with prototypes
- Path to multiple builds: that may start with a handful of prototypes and pilot units, but there's a clear plan for repeatable production
- Smaller than the giants: unlike large pack integrators who often won't engage until you're at very high volumes and large NRE budgets, we're willing to support smaller OEM programs and early-stage platforms
Not a Good Fit
- One-off personal projects: single custom cars, boats, or DIY machines where our engineering process and pricing don't make economic sense
- Hobby builds: purely personal projects without a path to repeatable production
- Consumer drop-in replacements: we're not a source for marine or RV battery upgrades; consumer and marine-oriented battery solutions are better suited for those applications
- No production plan: projects without a clear path from prototype to repeatable builds
Bottom line: MonoLith is for commercial and OEM programs building repeatable products or platforms. If you're building a real product or fleet, even at modest volumes, we're here to help.

Controls & Communications
The BMS publishes limits & health on CAN and supervises HVIL, precharge, and contactors. Your VCU (provided by you) commands the loads within published limits. The BMS CAN messages are configurable to match your VCU. DBC is provided; message map & rates are documented in an ICD.
Integration highlights
- • CAN 2.0B (11/29-bit), up to 1 Mb/s
- • DBC provided for telemetry, limits, faults
- • VCU-compatible: BMS enforces safety, opens on fault; VCU provided by customer
- • Configurable IDs/rates (documented ranges in ICD)

For engineers (the useful details)
Program & commercial
Straight talk
- If you need a UL-listed, road-legal pack next month, this isn’t it.
- If you need a credible pilot pack quickly, with a clean path to certs, this is exactly that.
- Lock cells/cooling/enclosure early; it saves months and five figures.
Getting started
- Duty cycle (CSV/plot), thermal constraints, envelope.
- Cell family (we’ll recommend from your load case).
- Required tests (UN38.3, EMC, vibe, IP).
- CAN map and connector set.
- Approve build sheet; we start cutting metal.
