FAQ
Q: What does 15A Continuous Discharge Rating (CDR) mean?
A: It means this battery can safely and continuously deliver 15 amps of power without overheating or being damaged. This makes it perfect for high-drain devices requiring consistent power.
Q: Can I use this battery for my camera?
A: Not recommended. Most cameras using 18650s are designed for much lower current (usually <5A). Using this high-drain cell might overheat or damage the camera's internal circuits.
Q: What is the difference between Flat Top and Button Top?
A: Flat Top batteries have a flat positive terminal, suitable for most spring-loaded devices like power tools and some flashlights. Button Tops have a protruding button. This item is Flat Top.
Q: Can I charge this battery above 4.2V?
A: Absolutely not. Overcharging can cause the battery to swell or explode. Always use a dedicated Li-ion charger that stops charging at 4.20V.
Q: What safety precautions should I take?
A: Avoid short circuits, high temperatures (>60°C), physical puncture, or incineration. Always use equipment with built-in protection circuitry (over-charge/over-discharge protection).

Security
Fits my cordless rotary tool, provides steady 15A. The pulse 30A helps on startup. DMEGC did a nice job.
15A continuous but handles 30A pulses in my flashlight turbo, no problem. 2500mAh is real, lasts a good while.
When pulsing 30A for 5 seconds, the cell gets noticeably warm. Not dangerous, but monitor it. Fine for bursts.
Tested at 0.5A, I got 2380mAh and 2410mAh. Slightly below 2500. But the 15A continuous is accurate.
Using in a Convoy S2+ with FET driver, the 30A pulse allows max brightness. Cell stays cool at 15A continuous.
