We represent registered Indian investors, EPC players, and industrial energy storage end users.
Our intention is not to buy machinery for ourselves, but to sell, deploy, and technically support your complete battery assembly lines in India, while jointly building a long-term, risk-shared manufacturing partnership for the Indian market.

We request responses only from OEMs capable of supplying COMPLETE, integrated, proven turnkey assembly lines and supporting them throughout their entire production life cycle.

1. Project in One View

Product Scope
• LiFePO₄ (LFP) BESS manufacturing
• Cell → Module → Pack → Rack → Container

Cells
• Imported Prismatic Cells
• 3.2V | 100–314 Ah
• BYD / CATL / equivalent Tier-1 cells

Planned Capacity
• Phase-1: 1 GWHMWh per year
• Phase-2: Expandable to 3 GWH MWh per year (double shift)

Automation Level
• Semi-automatic (stable, serviceable, scalable)

Target Applications
• Grid-scale BESS
• Solar PV + Storage
• Industrial captive power (DG / GT / fossil-fuel replacement)

2. What We Are Buying (Critical)

We (and our clients) are buying ONLY complete, integrated, proven assembly & integration lines.

The OEM must take technical ownership from:
Imported cell input → containerized BESS output

Partial lines, loose equipment sales, or “customer-integrates-rest” approaches are not acceptable.

3. Engineering & Production Commitments (Mandatory)

OEM must clearly define, application-wise:

• Series / Parallel (S/P) configurations
• Pack voltage, Ah, and kWh
• Rack and container voltage architecture
• PPM – Packs Per Minute
• Annual achievable MWh per configuration

OEM must commit to:
• Achieving agreed PPM, yield, efficiency, and quality KPIs
• Supporting multiple configurations on the same line

4. Installation, Commissioning & Ramp-Up

(This decides the partnership)

We recognize the first 3–6 months as the highest-risk phase due to:
• Teething issues
• Debugging & line balancing
• Yield loss & breakdowns
