So today I purchased 2 Sony US18650VTC3 High drain batteries that has a max continuous discharge of 30amps. I got this because I believe it's safer since the coils that i'm building for my rebuildables are drawing around 8 amps. That gives me enough room. However, I then thought to myself, if this is safer than other batteries why is it that people still buy batteries that have a lower amp cont./pulse discharge? Is there a huge difference in performance? Hope this makes sense.
