Samsung 30Q 18650 3000mAh 15A Rechargeable Battery – INR18650-30Q

The Samsung 30Q is an excellent cell for users who want a lot of capacity without a lot of discharge/drain capability. This cell is one of the best all-rounders on the market, with a good discharge rate, capacity and price.

This cell offers a 3,000 mAh energy capacity and a maximum continuous discharge/drain rating of 15 amps without any temperature cut. It has a greater capacity than the Samsung 25R while drawing less current. It also has an excellent cycle life, which should be taken into account while making your purchase.

When utilised at 15 amps, this cell is very efficient and steady. This is another excellent cell that may be found in power packs, high-output power banks, BMSs, power tools, and high-performance flashlights. This cell has shown itself in numerous applications and is extremely adaptable.

Samsung 30Q use in vapes

With a high output and a decent capacity, it’s little wonder these cells are popular among vapers. Recently, Samsung, along with most other manufacturers, have started printing anti-vape messages on their cells, and our current stock of Samsung 30Q has those markings. Nothing internally has changed, just the warning on the outside. It’s worth remembering that these are cells, not batteries, they have no protection against short circuiting and mishandling can lead to some very unfortunate results.
