Another way to keep is straight in your head is just noting that a given battery equals a discrete amount of energy (& power.) Hooking two batts in series or par does not change the total amount of energy, ie it is two units.

EG. Energy equals power*time or (voltage*amps) * time.
A 3S 5Ah cell equals--> 3*(3.7V) *5Ah= 55.5Wh (watt hours)

So if you take two packs, the total Energy is 111Wh no matter what.

Series: ie 6S 5Ah--> 6*3.7V*5Ah=111Wh
Par: ie 3S 10Ah --->3*3.7V*10Ah=111Wh

You know the guy at the hobby store was FOS, bc according to him:
2x 3S 3Ah packs in series = 6S 6Ah... try the math
3S 3Ah= 33Wh => two packs =66Wh
LHS "magic packs": 6S 6Ah= 133 Wh... nope, fail. You didn't somehow create energy just by changing wires. If you could you'd solve the world's energy problems and win several Nobels for overturning fundamental laws of physics. lol
woosh over my head. I'm not at that level yet.

So regardless of Series or Par I still need a 30c which ever way I go ..?

If the 2200kv is 1250 watts DO I just need 1300 watts of battery power ?
