Energy Storage Engineered to Outlive Your Home.
American-made LiFePO4 battery storage systems with zero field failures, 16,000+ cycle life, 25-year warranty, and military-grade encrypted monitoring. Built by engineers who learned the hard way — so you never will.
Six Reasons We Exist — And One Reason We Don't Quit.
We didn't set out to build the cheapest battery. We set out to build the one that refuses to fail. Every decision — from the cell chemistry down to the screw threads on the enclosure — is engineered to outlast the competition by a factor of three.
LiFePO4 Only
Lithium Iron Phosphate. Not NMC. Not NCA. Not cobalt. LiFePO4 cannot thermally run away under normal abuse. Thermal onset at 251°C — over 100°C higher than the NMC chemistry most competitors use. No fire. No explosion. No mining controversy.
Audited 314Ah Prismatic Cells
Every cell in every ECHO module is a 314Ah prismatic LiFePO4 — audited at receipt, serial-tracked, and verified from -30°C to +60°C. 175+ Wh/kg energy density. We qualify every supplier, test every shipment, and trace every cell to the system it ships in.
16,000+ Cycle Life
Most competitors spec 3,000 to 6,000 cycles. Our cells are rated for 16,000+ at 80% depth of discharge. At one cycle per day, that is 43 years of service — longer than most homes stand. That is why we can offer a 25-year warranty with a straight face.
Four-Layer Fire Protection
Cell → Module → Enclosure → BMS. Cell-level stability. Module-level containment verified by UL 9540A. American-made 5052 H32 aerospace aluminum that melts 700°F above thermal runaway. Real-time BMS with 28+ minute early warning.
5–25 Second Monitoring
The AEGIS Command Center polls every individual cell every 5 to 25 seconds with military-grade encryption. Competitors check once per minute at best — and most only monitor at module level. We see problems before they become problems.
American Made
Every enclosure, every battery box, every piece of monitoring hardware — fabricated, assembled, and finished in the United States. No white label. No contract manufacturer. No outsourced quality control.
One Architecture. Infinite Configurations. Zero Compromise.
From a 48 kWh residential system to a 144 kWh commercial platform with DC Fast Charge, every AEGIS Shield is built on the same obsessively engineered foundation. Audited prismatic cells, American aluminum, AEGIS Brain intelligence.
The Fastest, Most Secure Energy Monitoring on the Planet.
Every AEGIS Shield ships with an AEGIS Brain — a dedicated on-site edge gateway that reads every inverter register, every BMS cell, every temperature sensor, every 5 to 25 seconds. That data streams to the AEGIS Command Center in the cloud with military-grade encryption.
Access your system from any device, anywhere in the world. See live gauges, historical trends, cell-level balance, energy totals, savings calculations, and automatic alerts. Your Command Center never sleeps, never forgets, and never lies about what your system is doing.
Built From Failure. Engineered to Never Fail Again.
THE COUNTERFEIT DISCOVERY
Fake CATL cells flood the battery market. Systems across the industry begin to fail. While competitors deny, blame customers, or quietly disappear, we absorb $3 million in direct costs replacing every affected unit. Then we get to work. The team pulls off business-as-usual and starts prototyping a new battery module we can vouch for down to the last cell.
ZERO FAILURES · A NEW STANDARD
The ECHO 3.0 platform launches with audited 314Ah prismatic LiFePO4 cells, redesigned BMS, and cell-level monitoring. Every variable controlled in-house. Since day one: zero field failures.
AEGIS SHIELD GOES NATIONAL
The full AEGIS Shield product line ships nationwide — four configurations spanning residential to industrial. The AEGIS Command Center comes online with military-grade encryption and cell-level polling at 5–25 second intervals. The mission: not just to sell batteries, but to defend the power of every home, business, and base that depends on us.
Your Grid Is a Landlord. We Built the Exit.
Stop renting electricity from a monopoly. Own the system that powers your life — with a 25-year warranty, 16,000-cycle battery, and a Command Center that never sleeps.
