The ones that i use now are high drain and 30a.is it okay to go down to 20a? I have the Sony v4 18650s

There are 2 ratings on the batteries. Constant drain and pulse. Many rewraps state just an amp rating. They do not specify pulse or constant. The highest you can get in 18650 is 20amp constant and 30amp pulse. The LG hg2 are safe. What brand of battery are you using now?
