Samsung 30Q INR 18650 3000mAh 3.6V Unprotected High-Drain Lithium Ion Flat Top Battery

With a 3000mAh capacity that makes other 18650s look like AAAs, Samsung's 30Q seems like a never-ending well of power. Due to the massive power capacity of the 30Q you'll have to recharge this battery much less often other battery you've used in the past allowing you to lighten the load by leaving USB cords and wall chargers at home. It would be difficult to find a better option for powering electronics at lower amperages (15-20A). The perfect cell to buy for your high drain devices, the 30Q 18650 saves money in the long run with multiple recharge cycles.

Warning: Use only with compatible devices and chargers. Research and inform yourself on the proper use and handling of Li-ion cells and device compatibility.
