There are many high performance batteries that exist on the market today, but none quite like the 2900mAh Flat Top batteries by Efest. Not only are these batteries backed by a well respected brand, but they’re also engineered for advanced applications, since they offer a hefty maximum continuous discharging current of 35 amps. The 35A IMR 18650 2900mAh batteries by Efest are ideal for sub-ohm builds and lengthy vaping sessions that other batteries just can’t handle.
