New to Lipo batteries so could really use some assistance. Got a new Senton 6S but since my son is new to the hobby and I'm just getting back into it after 15 years, I don't think it would be smart to go with a full 6S capacity battery as the speed will be too high starting off, especially for my 13 yrs old son. I see the specs say the Senton 6S can run 3s,4s and 6s lipo as long as the minimum spec is 35C 5000mAh. Does that mean I can start off with just one 3S or 4S battery to reduce speed? If I can run just one 3S battery than when we are ready I can add a second to equal the 6S max capacity? What battery(s) do you guys recommend? Sorry if this is a dumb newbie question. Thanks guys!
