I think the 10XL should be ok on 5s. Your going to use 5s aren't you? Because 21V is what you'd put in the calculator if you were using 6s. 5s comes off the charger at 21v, but when you put load on them the voltage will come down. 5s is 18.5v nominal, and for the calculator, use maybe 17-18v. Good batteries will hold their voltage better than lower quality batteries under load.
