MonoLith™ Battery Systems

Up to 498 kWh and 3,568 kW in a Single System

Parallel-Array Architecture for Scaling Energy and Power

MonoLith™ packs are designed to compose in parallel: 2–8 arrays connected to a common DC bus. Each pack delivers up to 62.2 kWh and 446 kW; parallel composition scales energy and current linearly with no system-level cap. No custom engineering required—all arrays are pre-validated configurations in the catalog. Pick a base config and parallel count in PackForge; system is field-ready with stable lead times.

Parallel Composition Envelope

Composed system performance depends on base configuration and parallel count. Current and power scale linearly — each pack is a self-contained enclosure with its own busbars.

Parallel-Array Architecture

MonoLith™ battery packs are engineered from the ground up for parallel composition. A single pack delivers up to 62.2 kWh and 446 kW; when you need more energy or power, you compose 2–8 packs in parallel, all sharing a common low-voltage DC bus. Current and power scale linearly with pack count — each pack is a self-contained enclosure with its own busbars, so there is no system-level current cap.

The system is not "stacked" in the colloquial sense (no custom wiring harness design, no bespoke BMS tuning). Instead, each pack maintains its internal cell balancing and thermal management, while external paralleling logic is handled by validated power electronics configurations. This means: zero custom engineering, simplified qualification, and field-proven reliability across hundreds of installations.

How Parallel Scaling Works

Pick a base configuration: for example, a 400V, 30 kWh MonoLith™ pack rated for 200 kW discharge. Specify a parallel count (2–8 packs). The composed system then offers: 30 × (parallel count) kWh, and up to 200 × (parallel count) kW — current scales linearly with no system-level ceiling. A 2-pack array reaches ~60 kWh and ~400 kW; an 8-pack array can reach 240 kWh and 1,600 kW on the DC link.

All packs retain the standard 170 mm height. Footprint (X and Y dimensions) grows proportionally with pack count. No custom mechanical integration is needed; all arrays are pre-cataloged in PackForge. Once you select a base config and parallel count, the system is field-ready: known lead times, stable BOM, certified thermal dissipation curves.

When to Use Parallel Arrays

Choose parallel composition in three primary cases: (1) Mission energy is insufficient with a single pack. A 62.2 kWh pack supports ~250–350 miles of range in a mid-size EV; longer routes or high-duty cycles (commercial fleets, off-road rigs) demand 200–498 kWh. (2) Peak power demand exceeds 446 kW. A single pack delivers up to 446 kW rated; if your power electronics demand 800 kW or more during acceleration or rapid discharge, parallel packs scale current linearly. (3) Redundancy is required. An N+1 failure mode (one pack fails, system continues at reduced performance) is standard in aerospace, grid-scale storage, and mission-critical vehicles.

Contrast this with series-connection strategies: series raises voltage (e.g., two 200V packs → 400V nominal bus), but does not scale energy at a fixed voltage. MonoLith™ handles series internally through cell-stack height and module count; parallel is the external lever for scaling energy and current capacity.

Compose Your System in PackForge

In the PackForge Configurator, drag the kWh or kW sliders above the single-pack ceiling (62.2 kWh / 446 kW) to automatically enter composed parallel mode. Select your base config and parallel count. Export a pre-filled RFQ with one click. No custom tooling.
