What battery have you got that's 50a. is that continuous or pulse.If you want to stay super low, you would need a 26650 mod of some kind. The batteries come in around 50 amps. The simple solution is trying .5 or so to see if you like the taste, but 26650's will always be around whenever you want them. The only authentic 26650 I've ever messed with is a super t simplicity. It was a really nice mod. Sadly, the mrs. won;t let me get the 18650 version. Damn bills.
