I can't lie I like big batteries. The latest in the race 46110. https://www.nealsgadgets.com/products/lumintop-gt110-flashlight. Other lights; https://www.nealsgadgets.com/products/lumintop-mach-46950-flashlight https://www.nealsgadgets.com/products/lumintop-gt46-flashlight So we have 46800 25,000mah, 46950 32,000 mah and 46110 with 38,000mah. These batteries have the same diameter as 3-21700's but with a little more length and a whole lot more capacity. Most of these cells are manufactured by Eve geared towards BMW and Tesla in the EV race. Is this a possible trend for newer soda can lights and long range throwers?
