focus Fernando jr. video for the more survivalist and they have a great little tip for you guys maybe you're familiar with these maybe not but these are 14500 lithium-ion batteries with an incorporated micro USB port for recharging now these are great I'm loving these I'm running this one in my ADC lights and I cannot recommend them enough I'm gonna be leaving the link below in case you want to purchase these in Amazon they go like for 10 12 bucks give or take I think so they're pretty affordable the thing is this you're talking about a battery in case you're not familiar with a different battery types where the 14 500 is a lithium ion battery similar shape as your standard double-a so this would be 14500 battery it's running at 3.7 volts which is higher than your double-a but it's the same form factor so you can throw if your flashlight is rated for lithium-ion 14500 you can throw it i
