Announcing SERP Battery (C–Zn) — Higher Stability, Cleaner Integration

    We’re introducing our next-generation carbon–zinc (C–Zn) SERP Battery stack. Built on soil-based galvanic energy harvesting, the new configuration delivers more stable output and improved energy budgets for low-power electronics, while preserving our core advantages: no wiring, no solar panels, and near-zero maintenance.
    *** What Changes with Carbon–Zinc
    Cathode kinetics: Porous carbon (graphitic) cathodes support oxygen-reduction reactions in aerated soils, reducing polarization vs. metal–metal pairs under similar conditions.
    Lower internal loss: Optimized electrode geometry and ionic path length improve effective series resistance in typical field deployments.
    Compatibility: Fully compatible with our DC–DC + buffer architecture; drop-in for LoRa nodes and short-burst video modules.
    *** System Architecture (unchanged, proven)
    C–Zn soil cell(s) → high-efficiency step‑up DC‑DC → rechargeable buffer cell → device (LoRa / IR / camera)

    Operating Conditions (engineering guidance)
    Soil moisture: Works across a wide range; best stability in consistently moist, aerated soils.
    Temperature: Designed for sub‑zero to high‑summer conditions; buffer sizing recommended for extremes.
    Placement: Favor shallow, oxygenated layers for the carbon cathode; ensure robust mechanical anchoring for zinc anode.

    Target lifespan: up to 3 years under a typical low-duty cycle (e.g., LoRa uplink every 15–30 min; 5–12 short video clips/day), ambient −15…+31 °C, and soil conductivity ≥ 0.2 mS/cm. Field-validated in Estonia

    Sustainability
    Recyclable zinc anode and carbon cathode; low material mass per node.
    Ground-level installation; minimal surface footprint; retrieval at end‑of‑life.
