Samsung 30T 21700 3000mAh 35A Rechargeable Battery – INR21700-30T

This is currently the most powerful Ultra-High Drain cell available. No other cell on the market compares to the current punch that this one provides. The Samsung 30T has a 3,000 mAh capacity and a real 35 amp Continuous Discharge/Drain Rating without a temperature reduction. It barely warms up to 67 degrees Celsius with 30 amps of continuous discharge/drain. That demonstrates the ingenuity and research and development that went into making this cell. However, this cell is useless unless you use it in an Ultra-High Discharging/Drain device that draws more than 20 amps, at which point it reveals its actual powers. There is hardly little voltage sag on the Samsung 30T.
