Technical Specifications

Engineering Excellence & Safety Innovation

1. High Energy Density for Field Autonomy

Designed for technicians on the move, the NS-3S2P series offers an exceptional energy-to-weight ratio. The 11.1V 5.2Ah capacity is optimized to provide hours of continuous operation for handheld flaw detectors, reducing the need for mid-shift battery swaps in remote locations.

2. Global-Standard Protection System (BMS)

Safety and stability are managed by an advanced Protection Circuit Module (PCM/BMS) utilizing the most sophisticated chips from Japan and the United States. This ensures precision management of the 18650 cells, including:

• Short Circuit Protection: Instant cut-off to protect sensitive NDT circuitry.³

• Overcharge & Over-discharge Protection: Maximizing the lifespan and safety of the lithium chemistry.⁴

• Over-current Protection: Safeguards against power spikes during high-voltage pulse generation.

3. Modular & Versatile Design

Our battery architecture supports modular design, allowing for multi-parallel and multi-series combinations to meet specialized voltage or capacity requirements. This flexibility makes it the perfect power foundation for a wide range of industrial supporting instruments.
