10s4p + 10s2p making 10s6p. Possible?

I do it on my board. I have not had any problem so far and I have ridden it like this for over 500 miles.

Evolve GTX 2nd battery in parallel

I thought the same thing. Someone awhile back even told me I’d be getting 13-ish mile range on a 10s4p but I went with the esk8 calculators which was as you said double the range. So it seems to be the range for that battery running on AT tires.
