Blackcell IMR18650: High-Capacity Cell for High-Wattage Mods
The Blackcell IMR 18650 3100mAh 40A Battery is designed for the modern high-drain electronic device, specifically regulated vape mods. This cell is optimized to balance a lengthy 3100mAh runtime with an impressive 40A max discharge rating (estimated at a 20-25A continuous discharge rate for conservative safety). It utilizes IMR chemistry, a safer internal composition that provides stability under load. This battery is the ultimate choice for vapers who use dual-battery devices and prioritize long battery life for all-day use without sacrificing the power required for large coil builds.
Core Assessment: Advantages and Critical Limitations
- Pro: High 3100mAh capacity provides exceptional longevity, maximizing the time between charges for moderate-to-high wattage use.
- Pro: Features a high maximum discharge rating (40A) suitable for safe use in regulated box mods up to 150W (with a pair).
- Pro: Uses safer IMR (Lithium Manganese Oxide) chemistry, known for better thermal stability compared to standard Lithium-ion.
- Con: Like all high-performance cells, the 40A rating is a pulse/max rating; the safe Continuous Discharge Rating (CDR) is lower (estimated 20-25A).
- Con: Unprotected (flat-top) cells require extreme vigilance regarding external wraps and must only be used in devices with built-in electronic protection.
Performance Data: Essential Features & Their Advantage
- High Capacity Rating: Features a 3100mAh capacity, providing long periods of use before requiring a recharge cycle.
- Form Factor: Standard 18650 size (18mm diameter by 65mm length) ensures compatibility with the vast majority of regulated vape mods.
- Max Discharge Current: Rated for a 40A maximum pulse discharge, providing the necessary current delivery for high-wattage vaping (always operate within the mod’s limits).
- Nominal Voltage: Operates at a standard 3.7V nominal voltage, maintaining consistent power delivery throughout the discharge cycle.
- Chemistry Type: Utilizes IMR (Li-Mn) chemistry, which is designed for high-drain applications and is inherently more stable and safer than traditional Li-ion cells.
- Flat Top Design: Designed with a Flat Top terminal, ensuring maximum compatibility with most box mods and external chargers.
- Rechargeable: Rated for numerous recharge cycles, offering long-term, cost-effective use.
⚠️ SAFETY AND EXCLUSION DETAILS
These Blackcell IMR 18650 batteries are unprotected, high-drain cells designed exclusively for expert users of regulated devices. It has three critical safety requirements:
- These cells should never be mismatched with other cells and must only be used in pairs in multi-battery mods.
- They must be charged in a dedicated, external Li-ion battery charger and never charged via the mod’s USB port.
- Users must immediately stop using the battery if the outer plastic wrapper is damaged, as this creates a critical short-circuit hazard.
