What FELINE Pty Ltd does

Feline Industries Pty Ltd (trading as Feline and also as Southvolt) is an Australian battery manufacturer operating from Burleigh Heads, Queensland. The company develops and produces lithium iron phosphate (LFP) pouch cells and battery modules with an explicit emphasis on safety — its core differentiator is a non-flammable LFP cell platform validated through box-cutter safety testing — combined with sovereign Australian manufacturing. Its product portfolio comprises a 3.2V 50Ah LFP pouch cell, 25.6V 100Ah and 51.2V 100Ah battery modules, and a specialised underwater pack, the DeepSea 1 (48V, 5kWh), engineered for pressure tolerance to 160m and targeted at ROVs, AUVs, and marine systems. Manufacturing is anchored by a 250 MWh automated assembly line commissioned in July 2025, and the cells are UN38.3 certified for international transport as of May 2026.

The company sells direct to enterprise customers in B2B fashion, with no disclosed pricing and no named customer accounts. Its go-to-market targets two primary verticals: underwater/marine systems (ROVs, AUVs, subsea robotics) and broader critical energy applications (defence, critical infrastructure backup, remote power), where safety, reliability in harsh environments, and sovereign supply are the dominant purchase drivers. Distribution is purely direct enterprise sales; the company has no disclosed channel partners or resellers. Revenue is not publicly disclosed, no funding rounds have been reported, and the headcount of five suggests the firm is at an early commercial stage despite its manufacturing scale, with product spec sheets for several SKUs still flagged as "update in progress".

Broad incumbents

• EVE Energy: Large Chinese LFP and pouch cell manufacturer with global automotive, ESS, and specialty product lines. Direct product overlap with Feline's 3.2V 50Ah pouch cell format, but operates at multi-GWh scale and serves mass-market customers.
• Saft (TotalEnergies): French specialty battery manufacturer serving defense, space, marine, and industrial markets with high-safety Li-ion and primary chemistries. Comparable to Feline's positioning in critical / mission-critical energy systems, but at vastly larger scale and broader portfolio.
• Akasol (BorgWarner): German manufacturer of high-power Li-ion battery systems for commercial vehicles, rail, marine, and industrial applications, now a BorgWarner subsidiary. Overlaps with Feline's module/pack assembly capability and target markets in heavy-duty and marine energy storage.
• CALB (China Aviation Lithium Battery): Major Chinese LFP cell and module manufacturer serving EVs, ESS, and specialty applications. Comparable cell/module product mix to Feline, but with established global automotive customers and significantly larger R&D and capex base.

Direct peers

• RELiON Battery: US-based LiFePO4 battery manufacturer focused on marine, RV, solar, and industrial markets with module-level products (12V/24V/48V). Comparable target customer base to Feline's critical-applications / marine focus, with overlapping module SKUs.
• Kokam (SolarEdge): South Korean specialty Li-ion cell and pack manufacturer (now part of SolarEdge) with strong presence in marine, defense, and UPS applications. Comparable to Feline's safety/critical-power positioning and pouch cell heritage, with established defense and marine references.
• Corvus Energy: Norwegian specialist in large-format lithium battery packs for marine and subsea applications (ferries, offshore, ROVs). Most direct comparable to Feline's DeepSea 1 underwater pack, with overlapping target customers in marine autonomy and harsh-environment energy storage.
• Subsea Energy: UK-based specialist in pressure-tolerant subsea lithium battery packs for AUVs, ROVs, and subsea installations. Most direct product-level overlap with Feline DeepSea 1, competing for the same underwater robotics and subsea instrumentation buyers.

Regional players

• Magnis Energy Technologies: ASX-listed Australian battery and materials company developing LFP cell capability and downstream battery projects. Regional peer sharing the 'Australian sovereign battery' theme, though earlier-stage on cell manufacturing execution.
• Energy Renaissance: Australian LFP battery cell and storage manufacturer based in Tomago, NSW, focused on domestic and Asia-Pacific ESS markets. Closest regional peer given shared 'Australian-made sovereign battery' positioning and overlapping ESS/critical-infrastructure customer narrative.
