Samsung 25R INR 18650 2500mAh Battery


The Samsung 25R INR 18650 2500mAh Battery is of very high quality and has a very economical price point to book-end it. This is an excellent balanced cell in terms of performance and reliability. Also this cell has a very good equilibrium with a moderate-high capacity of 2,500 mAh in energy, while having a high maximum continuous discharge/drain rating of 20 amps (Without any temperature cut involved). This cell is very stable, even when it's pushed to its max rating. This cell has about everything you could desire in a Li-Ion cell, as you can see from some of its attributes.

    I probably should have done more research into the differences between brands. These batteries drain quite quickly

    Great batteries, I have 6 of these batteries and i have pushed them hard on a 300w mo, vaping consistently at 150-220 Watts from full charge to dead, The batteries barely get a little bit warm, and maintain a consistent output and balance very well.
