Description (What It Does)
- BattRelay is a curated B2B directory that matches retired EV battery packs with the solar-plus-storage crowd: micro-grid developers, C&I installers, community-solar projects, refurb shops, even start-ups building modular power banks.
- Each listing shows the real nitty-gritty—pack chemistry, remaining kWh, State-of-Health %, warranty terms, price per kWh, location, and bundled logistics—so buyers can stop trawling LinkedIn groups and Excel graveyards.
Pain Point It Solves
- Opacity: Nobody trusts a Craigslist ad that says “Nissan Leaf pack – good condition.” BattRelay supplies verified diagnostics (BMS pull or third-party test report).
- Fragmentation: Retired packs sit in OEM warehouses, salvage yards, or behind refurbishers’ gates. The directory aggregates them in one searchable place.
- Risk & Admin Hassle: Warranty info, certifications (UL 1973 / IEC 62619) and freight partners are baked in, cutting the legal & logistical homework that scares small installers.

Marketing Strategies (How to Promote This Directory)
- Authority Content & SEO: Publish battery-health benchmarks (“Top 20 packs by $/usable kWh”) and case-study blogs.
- Optimise long-tail keywords like “second-life battery supplier California” or “BMW i3 pack for solar farm.”
- Early-Mover Perks: Free premium listing for the first 100 suppliers; spotlight stories in a monthly “Battery Re-Use Bulletin.”
- Niche Facebook Communities: Share teardown photos, SoH tips, and regulatory updates in energy-storage channels—drives organic referrals.

Data Points Needed to Build This Directory
- Pack Identity: OEM, model year, serial/VIN, battery chemistry
- Health Metrics: Original capacity (kWh), current State-of-Health (%), cycle count, internal resistance
- Commercial Terms: Price per usable kWh, remaining warranty (months or cycles), safety-certification status
- Logistics Details: Current location, hazmat classification, available shipping partners, typical lead time
- Seller Profile: Company type (OEM/refurbisher/recycler), contact info, ESG or sustainability credentials
How to Source These Data Points
- OEM Take-Back Streams: Automakers already harvest diagnostic data when packs are removed—sign MOUs for API or CSV dumps.
- Refurbishers & Recyclers: Firms like B2U Storage Solutions publish SoH after bench-testing; scrape or receive feeds.
- Fleet Telematics APIs: Bus, taxi & logistics fleets often export BMS logs (CAN bus) before auction—integrate via webhook.
- Regulatory Filings: Many regions require end-of-life battery reporting; mine public e-waste logs for pack IDs.
- Certification Databases: UL & TÜV share listings—cross-reference to flag packs already safety-qualified.
Why It’s Unique
- Verified Health Layer: Most “marketplaces” list batteries like used furniture; BattRelay demands diagnostic uploads or third-party lab stamps.
- Vertical Match-Making: Goes beyond seller-buyer; also pairs logistics, insurance, recycling end-points—one-stop circular-economy hub.
- Live Price Indexing: Aggregated $/usable kWh and CO₂-saved dashboards give buyers confidence (and great newsletter fodder).
- Timing Sweet-Spot: IDTechEx pegs the second-life market at US $4.2 billion by 2035, with 6 million battery packs retiring each year by 2030, a rising tide screaming for structured data, right now.
