Think you mean 11.1v 3s lipo, I had a primal charger as well, it's a pretty good charger but once you get a few lipos it's better to have a dual charger that can at least hit 10amps on each port or if you're only going to have a couple lipos a single charger is good but you want at least 10amp charge rate, I don't own 3s lipos but my primal would charge my 2s 5000mah in about 80min. at 4amps so you're going to be waiting forever at 2 amps you'll probably only get to run that battery once a day, no better then a stock wall charger that comes with some rtrs, if you're into the hobby a charger is a big deal just dish out the cash for a good charger and you'll be happy, I sold my primal and picked up the hitec x2 400 for 175$ can charge 20amps on each port
