LiTrue a manufacturer of high energy-density lithium battery cells and custom battery packs, today announced the launch of the PE42N-EF, a 42Ah, 3.85V ultra-high energy density solid-state anode-free cell. The new cell delivers 490Wh/kg energy density, 3C continuous / 5C pulse discharge, and operates across a -43°C to 55°C temperature range, targeting industrial UAV platforms and custom high-energy battery systems. Full specifications are available on the PE42N-EF product page.
Engineered for Cold-Weather Reliability
Low-temperature operation is a known weak point for many high-energy cells: available capacity drops, internal resistance rises, and systems sized for mild climates can lose flight time or power margin once temperatures fall. The PE42N-EF is built around that constraint, pairing a -43°C to 55°C operating range with 42Ah of capacity in a compact 340g pouch format.
The cell’s 3C continuous and 5C pulse discharge ratings give integrators headroom for takeoff, maneuvering, and other short high-load events without having to oversize the cell purely to cover peak current. As a bare-cell offering, it is intended for teams developing compact, temperature-tolerant battery systems — see LiTrue full range of battery cells for related configurations.

Application Areas
Industrial UAVs: Supports sustained propulsion demand and 5C pulse loads during takeoff, climbs, and payload maneuvers.
Cold-Climate Drone Operations: The -43°C lower operating limit addresses the capacity and power loss that can constrain winter deployments.
Portable Aviation Equipment: The 7 × 87 × 187mm pouch format and 340g weight help designers manage pack volume and mass.
Custom High-Energy Battery Packs: Suitable for integrators building series-parallel systems around a 3.85V nominal cell. For example, a 12S configuration yields 46.2V nominal and a 14S configuration yields 53.9V nominal. LiTrue’s engineering team can help scope a suitable configuration — see the full battery pack capabilities for pack-level support.
Part of a Broader Solid-State Anode-Free Platform
The PE42N-EF belongs to LiTrue’s solid-state anode-free cell platform, offered across multiple capacity tiers so pack designers can balance cell thickness, weight, and energy density before finalizing a module layout.

Availability
The PE42N-EF is now open for engineering sample requests, with a minimum sample order of 10 pieces (negotiable) and a sample lead time of 7–15 working days; bulk lead time is approximately 45 days, subject to volume and requirements. LiTrue also offers OEM/ODM development services, providing technical support from cell selection through complete pack design for UAV, AGV, and energy storage applications. Full details on the platform’s related cells are available in LiTrue product catalog.
