Power and endurance — one American platform.
American-made LFP / BMLMP cells, engineered for the two jobs the grid and defense actually need: Pulse-53 for high-power, certified military-grade duty, and Vault-314 for two decades of grid endurance. One Digital DNA platform behind both.
Same certified chemistry, tuned for opposite ends of the duty curve — raw power for the mission, deep endurance for the grid.
America's unique certified military-grade cell — high power and fast response for defense and mission-critical duty. When the load spikes, Pulse-53 answers.
Built for longevity — deep daily cycling for grid-scale and datacenter storage over two decades. The endurance cell for infrastructure that has to last.
The 53 Ah BMLMP power cell — America's certified military-grade cell, built for high-power, mission-critical duty and already proven at sea. Drag to inspect it from every angle.
The 314 Ah prismatic endurance cell — engineered for two decades of deep daily cycling on the American grid. Drag to inspect it from every angle.
Energy density sells consumer gadgets. Safety, cost, and cycle life build infrastructure. LFP wins on every axis that a grid or datacenter buyer actually cares about.
Iron and phosphate — abundant, cheap, and mineable at home. A supply chain that can be domesticated end to end.
Thermal stability the grid demands. LFP resists runaway by chemistry, not by add-on protection.
Two decades of daily grid duty from a single cell. Storage that outlasts the projects it powers.
The metric storage buyers optimize. Long life plus cheap materials wins the cost-per-cycle math outright.
Both cells, in full — built and charged by C4V technology in Endicott, New York. Complete electrical and mechanical specification, each carried by a Digital DNA record stamped on every cell.
The 53 Ah P-Series prismatic power cell — BMLMP chemistry, already in production and proven at sea. High power and fast response for defense and mission-critical duty.

The same cell serves the two fastest-growing storage buyers in America — the grid, and the datacenters straining it.
Frequency regulation, peak shaving, and blackout resilience — the fastest-responding asset on the grid, built for long-duration daily cycling. LFP's cycle life is what makes daily grid duty economic.
Power quality, ride-through, and demand shaping. Every gigawatt of new datacenter load needs firm storage behind it — and it has to be safe enough to sit next to the compute it protects.
The product advantage isn't only chemistry — it's how it's made. Autonomous, lights-out manufacturing with Digital DNA means consistent cells at under 2% scrap, 100% machine-vision inspection, and full powder-to-pack traceability on every unit.
American cells, for American infrastructure.
