SMC seems to be much better than what I am currently using (Zippy), and not that much more expensive.
Been using Gens ace / Tattu for the past 7+ years. They are my go to and have a wide selection.
they rank pretty highly too in the 100 amp chart, though a bit more expensive
Yeah and they make 6s 25Ah and 40Ah packs for my bigger bois.
