⚔️ Advanced Safety Protection: Precision & Power

Our ORB-7000-P features an advanced, multi-layered safety system. We don't use generic, off-the-shelf components. Instead, our protection circuitry is built with premium, high-performance el. parts sourced from world-class designers in Japan and the United States. This is real-world reliability, backed by verifiable specs.

🇯🇵 SEIKO (Ablic)🗾Japan-Engineered Precision ICs

At the heart of the circuit is a high-reliability protection controller (IC) from Seiko Instruments (Ablic) of Japan. This is an industrial-grade component trusted in applications where failure is not an option. It monitors voltage and current with extreme precision and reacts instantly to threats.

• Over-Charge Cutoff: 4.325V (Protects against over-voltage)
• Over-Discharge Cutoff: 2.5V (Protects against over-depletion)
• Ultra-Low Standby Drain: Consumes a virtually nonexistent 0.1μA, ensuring your battery's charge is preserved during storage.

🇺🇸 Alpha & Omega (USA) High-Performance MOSFETs

To handle the 7000mAh capacity, we use robust power transistors (MOSFETs) from Alpha & Omega Semiconductor, a leading U.S.-based company. These act as the gatekeepers, instantly disconnecting the battery during unsafe conditions.

• Over-Current Protection Cutoff: ~15A (Protection circuit is designed to trip at ~15A of load)
• Ultra-Fast Short-Circuit Response: Reacts to short-circuits in as little as 320 microseconds (μs) to prevent catastrophic failure.
• High-Efficiency / Low-Heat: These premium transistors feature ultra-low internal resistance. This minimizes heat buildup and "voltage sag," ensuring maximum power and efficiency are delivered to your device, even under heavy load.

💡 Intelligent & Robust Build Quality

• Superior Conductivity: Built on a dual-layer PCB with gold-plated contacts for perfect signal integrity and long-term durability.
• Low-Resistance Connections: Pure nickel tabs are used for secure, low-resistance connections throughout the assembly.
• Durability Tested: The entire protection assembly is thermally and humidity-tested to withstand real-world conditions.

⚠️ Important Safety Warnings: Read Before Use

Misusing or mishandling a lithium-ion battery can result in fire, damages, or personal injury. Your safety is paramount. Always read and follow these precautions.

✅ INSPECT BEFORE EACH USE: Always check the battery for any damage, such as a torn PVC wrap (skin) or a cracked terminal insulator. DO NOT use the battery if it is damaged in any way.

✅ Use only a high-quality, dedicated Li-ion battery charger.

✅ Always use the included protective case when transporting or storing the battery.

❌ Do not modify, disassemble, or solder directly onto the cell.

❌ Do not carry loose batteries in a pocket or bag with metal objects (keys, coins).

❌ Do not expose to extreme heat, direct sunlight, or dispose of in fire or water.

❗ Stop using the battery immediately if it emits an odor, feels extremely hot, or shows abnormal discoloration or deformation.

🚸 Keep away from children and pets.

🔦 A Note on Compatibility

This is a PROTECTED, BUTTON-TOP 26650 battery. Due to the added safety circuitry, its length is approximately 70mm (~2.75 in). This cell will only fit devices designed for protected 26650 batteries. It will NOT fit devices that require shorter, unprotected cells. Please measure your device's battery compartment before purchase.
