I'm in the same boat. I run SC and 1/10 ST with 2s 5000mah packs and 1/8 e-late model with either 1 4s 4400mah or 2 2s 5000mah wired together. Looking to buy a new charger and I like the hitec x4 AC plus for the fact of AC/DC and price. But would it be better in the long run to buy the x4 eighty and a power supply. Also only have 2 thunder ac6's now so would there be much of a decrease in charge time with the hitec's charging a single battery.
