MonoLith Battery Systems
Up to 560 kWh and 1,285 kW in a Single System
Parallel-Array Architecture for Scaling Energy and Power
MonoLith packs are designed to compose in parallel: 2–9 arrays connected to a common DC bus. Each pack delivers up to 62.2 kWh and 600 kW; parallel composition scales energy and current linearly, subject to thermal limits (Aluminum: 1,500 A; Copper: 1,800 A). 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 limits scale linearly until material thermal ceilings are reached.
| Configuration | Energy (kWh) | Power (kW) | Current Ceiling | Notes |
|---|---|---|---|---|
| Single Pack | 62.2 | 600 | Varies by config | Baseline; no parallel overhead |
| 2-Pack Array | ~124 | ~1,200 | Alu: 1,500 A | Cu: 1,800 A | Limited by material thermal rating |
| 4-Pack Array | ~248 | Current-limited | Alu: 1,500 A | Cu: 1,800 A | Power reaches thermal cap before 4× scaling |
| 9-Pack Array (Maximum) | 560 | 1,285 | 1,500–1,800 A | Absolute system ceiling; Copper preferred |
All 9-pack arrays maintain 170 mm height. Footprint (X, Y) grows proportionally. Enclosure material (Aluminum or Copper) determines current limit and thermal dissipation. Select in PackForge.
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 600 kW; when you need more energy or power, you compose 2–9 packs in parallel, all sharing a common low-voltage DC bus. Current scales linearly with pack count, subject only to material thermal ceilings: Aluminum enclosures are rated to 1,500 A continuous, and Copper enclosures to 1,800 A continuous.
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 (2–9 packs). The composed system then offers: 30 × (parallel count) kWh, and up to 200 × (parallel count) kW—subject to current limits and the thermal envelope. A 2-pack array reaches ~60 kWh and ~400 kW; a 9-pack array can reach 270 kWh and 1,800 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 200–560 kWh. (2) Peak power demand exceeds 600 kW. A single pack delivers 600 kW continuous; if your power electronics demand 800 kW or more during acceleration or rapid discharge, parallel packs scale current. (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 / 600 kW) to automatically enter composed parallel mode. Select your base config, parallel count, and enclosure material. Export a pre-filled RFQ with one click. No NRE, no custom tooling.
