Just got mine today. Pretty cool! Yeah it hooks up to your icharger so you still have control at how many amps you want to discharge up to. Im sticking with 30a for now. Keep it hooked up to your 2nd port and keep charging/cycling/discharging on 1st port. Raymond is cool and will help walk you through setting up your charger. Its small and compact. people are going to trip when they look at my pit table.
