⚠️ Safety & Handling

Important: For Experienced Users Only
This high-performance Li-ion cell is unprotected and intended for use only in devices with built-in safety systems (BMS or equivalent). Not for use in vape, e-cigarette, or similar devices.

Battery Safety Guidelines
Improper use may result in fire, injury, or damage. Always follow these precautions:

• Use only a Li-ion charger rated for 4.2V CC/CV charging
• Charge fully before first use. Never charge unattended
• Do not short-circuit, reverse polarity, or exceed rated current
• Do not expose to heat, water, or direct sunlight
• Do not disassemble, modify, or solder directly onto the cell
• Store in a protective case-never loose in pockets or bags
• Inspect before each use. Stop using if wrap or insulator is damaged
• Do not mix old and new cells. Do not force installation
• Discontinue use if cell emits odor, heat, or changes shape
• Keep away from children and pets

Short Circuit Risk
Unprotected cells discharge rapidly if terminals are bridged. This can cause extreme heat and damage. Always use with proper safeguards.

User Responsibility Agreement
By purchasing, you confirm technical knowledge of Li-ion safety and accept full responsibility for proper handling, charging, and use. Orbtronic is not liable for misuse or device incompatibility. If unsure, contact us 24/7-we’re here to help.
