Molicel P50B 21700 High-Drain Cell
Compatible with: Frolic by Limelight + YLL 3.0 Induction Heater
If you’re running a high-drain setup and want a 21700 that can deliver serious current with minimal sag, the Molicel P50B is a top-tier choice. It’s engineered as an ultra-high power cell with low impedance for efficient power delivery and less heat under load—plus more runtime and better longevity versus the P45B class.
Why the P50B
-
Ultra-high current performance for power-hungry devices (rated 60A continuous with an 80°C cut-off)
-
Low impedance helps reduce voltage drop and heat buildup under heavy load
-
More runtime + better retention than the P45B, with a slower heating rate and improved cycle life behavior
-
Wide operating temperature range (down to -40°C discharge) for demanding environments
-
Reliable, consistent quality when sourced as genuine Grade-A cells

Battery safety warning (read before use)
Lithium-ion cells can be dangerous if mishandled. Improper charging, shorting, physical damage, or using cells outside their intended design can cause fire, burns, or explosion risk. By purchasing, you agree you understand and accept these risks.
Safety basics
-
Never carry loose cells (use a plastic case—no pockets/purses)
-
Don’t short the contacts (keys/coins = disaster)
-
Do not exceed specs (check your device load + manufacturer ratings)
-
Charge with a quality charger made for Li-ion cells
-
Don’t charge unattended
-
Do not use damaged wraps or dented cells—re-wrap or replace
-
Store cool and dry, ideally around 3.5–3.7V for long-term storage
-
If a cell overheats, hisses, bulges, or vents: isolate it away from anything flammable and move it outdoors if safe to do so
