Lipo ? Is a LVC a must ?

or 2s1p in series will make 4s

the number at the front is how many cells the pack has

2s 2 cell - 3s 3 cell

the 1p and 2p is basically telling you if the cells have been parallel'ed to achieve a higher MAH

For instance

take two 2250mah 4s1p packs. parallel them, you now have 4500mah, 4s2p

now if you put them in series, you would have 8s1p 2250mah ?

I personally like the idea of running 4s2p as the cells are much cheaper than high MAH 2s packs ie 5000mah and PARALELLING the cells doubles the mah

those Zippy 4300mah 2s cells you will be better off using something like

I use one of these chargers, it balances while it charges, and has actuallyrevived a couple of TP 2200mah 3s packs that i overcooked in my trex, it can do 2 2s packs at once.

However, i would recommend the 4s2p configuration i suggested earlier
