Luis, Triton works great for the LIIon's we use and it's fairly inexpensive. I charge all of my lions exclusively with a Duralite charger, including the TBM brand, no issues yet, but I'm only about 500 flights into Liions, I know there are some in here who have over a thousand flights on Ion batts, it's easy to rack them up when you're getting 8 flights to a charge.
