Pretty sure I ordered wrong lipo battery
So, I have a dual brushless setup I just installed, each can handle 2s and well I wasnt thinking and ordered a 4s battery to feed them both at the same time. So I am pretty sure 4s doesnt divide itself to 2 s which would blow both the esc's up and while waiting for this 4s to come in the mail I need to find the correct battery I need to use.
I need the run times (mah) so the higher the better, but with dual motors it wont help. So with 2s whats the best option, staying with 2s, or going for 2s1p,2s2p? This would be the first time touching lipos so its a little new to me.
Forgot to post motor specs, I have 2 of these.
ESC Specs:
Continuous Current: 80A
Burst Current: 95A
Battery: 2 cells Lipo (5-6 cells NI-xx)
Motor type: Sensorless brushless motors

I only buy 2S1P LiPo batteries. You will usually start to see 2S2P packs when capacities go above 5000mah. Manufacturers will actually use 4 cells to make large capacity 2S packs by putting two of the four cells in parallel; thus combining capacities of the parallel cells. I don't want to dig deep in the subject, as people use very high capacity packs all the time. The problem that I can't past my head, with 2S2P packs, is chargers not being able to "see" all four cells through a balance lead....

When 2 cells are wired in parallel along with 2 cells wired in series the 2 cells wired in parallel are charged as one cell.
A 2S2P pack will have a 3-wire balance lead and the charger is set up to balance a 2-cell pack. The charger won't see 4-cells as the packs 4 cells are not all wired in series. It will only see 2-cells wires in series and the other 2 cells wired in parallel each act with the other cell as one large cell
This may help explain things a bit:
