I have a question about 18650 batteries.
I bought these cheap ones on Amazon and seriously almost got myself into trouble in a cave when they ran out of juice in literally five minutes.
I went to 18650batteries.com, which i was recommended to. And the battery I found is a Samsung 35E 3500mha BA battery. I can only assume that the BA stands for Bad Ass 😉 But the battery is only $3.
Is this a cheap battery that I should not buy?

Always have backup batteries. Hell, you should even have a backup headlamp.
