The price-performance winner at Keeppower in the 18650 size. As the model name P1834C already suggests with the large C, the built-in cell is a high-quality industrial cell from a Chinese premium manufacturer with 3400mAh.
Seiko protection up to 10A. PCB with short-circuit, overcharge and over-discharge protection. Developed for flashlights, LEDs, mech. Mods, etc. Laser pointers.
Please note the dimensions of the cell before purchasing! Due to the built-in electronics, the cell is not suitable for every application!
The height and diameter are larger than a standard 18650 cell without a PCB.
Please note that removing or damaging the protective electronics (PCB) can lead to a short circuit, fire or explosion.
Lithium-ion batteries are thermally stable and are not subject to any memory effect.
They work on the basis of lithium and are characterized by a high energy density.
