Yes. For example, Powerex batteries will operate the Launch Box hotter, as well as longer. Because of the significantly increased heat, the timing and breath control of the user must be proportionately more accurate to prevent overheating (which changes taste). Magic-Flight strongly recommends that new users become skilled with the stock batteries before trying higher energy density batteries.
Whether you choose LSD or HSD batteries, Magic-Flight ships and recommends Maha batteries. Our internal tests have shown them to be top performers. Comments in forums have shown that they are popular with MFLB users, who say that their superior performance more than justifies their slightly higher cost. Batteries have venting holes at the positive tip that are there to vent gases in case of shorting or overheating.
