ATEX Intrinsically Safe Battery Explosion Proof 3.6V 3800mAh Power Solution
Intrinsically Safe Power Solution for Firefighting Helmets & Hazardous Areas
The IS-642950TK is an intrinsically safe lithium polymer explosion proof battery developed specifically as a hazardous area power solution for firefighting helmets, emergency response devices, and special portable equipment used in potentially explosive environments.
Unlike consumer-grade batteries, this product is engineered around risk control, fault energy limitation, and mechanical protection, aligning with intrinsically safe design principles for hazardous locations.
Hazardous Area Power Solution - Not Just a Battery
In hazardous environments such as fire rescue scenes, confined industrial spaces, or flammable atmospheres, the primary function of a battery is not energy density, but controlled energy behavior under fault conditions.
This battery is designed to support:
- Limited electrical and thermal energy release
- Predictable failure modes
- Stable operation under temperature stress and mechanical shock
Intrinsically Safe Design Principles & Compliance Orientation
- Designed in accordance with intrinsically safe battery architecture
- Development references applicable hazardous area standards such as IEC 60079-11 (Intrinsic Safety - "i")
- Multi-layer electrical protection to minimize ignition risk
- Optimized internal resistance to manage heat accumulation
Certification can be supported as part of project-based compliance requirements.
Key Safety & Performance Advantages
- Explosion proof oriented energy limitation design
- Short-circuit, over-charge, over-discharge, over-current protection
- Reinforced ABS + PC enclosure for impact and heat resistance
- Stable discharge across emergency temperature ranges
- Compact structure optimized for helmet-mounted and body-worn devices
Typical Application Scenarios

Firefighting helmets require power systems that withstand:
- High ambient temperatures
- Vibration and impact
- Intermittent high-risk operational cycles
The IS-642950TK provides stable output, compact integration, and controlled fault behavior suitable for helmet-mounted electronics.
Emergency & Safety Equipment
Designed for portable safety devices used in:
- Emergency response
- Security and monitoring
- Special industrial handheld instruments
Not Recommended For
To ensure proper and safe application, this battery is not designed for:
- Consumer electronics
- High C-rate discharge tools
- Continuous high-power output devices
This product is engineered exclusively for safety-critical hazardous area applications.
