cant you just link up 2 7.4v batteries, you can pick up 7.4v lipo's cheap plus you can use them in 10th racing

No. Blimey.
Most 14.8V packs will be 4S1P (4 cells in series). 4S2P is two sets of 4 cells each wired in series - then wired together in parallel.
xS1P is normally superior - less cells to be matched together when being manufactured.
And, as I've said countless times now, 1/8ths require their own dedicated packs - if you run the packs in 10th as well, then one pack will likely end up more used than the other, and then you start running into issues of one of the packs being weaker than the other - which can lead to destroyed packs. Not only that, but whilst the manufacturers match cells within a pack, they don't match two packs. Each will be slightly different, which can only accentuate the problem.
Most LiPo cells are either made in China, Taiwan or Korea (practically no exceptions - these coutries have laws that are lax enough to allow the production at a reasonable cost).
If you're doing LiPo on a budget, take a look at the higher rated (30C+) Rhino, Turnigy and Zippy Flightmax LiPos at
Hobbyking - very popular, and for the price, unbeatable. Alternatively, try
Neu Energy (the same as the motors) in the US, as they have their own line of LiPos. Higher capacity 25C packs would be fine, if you're running lower capacities (<3500mAh) then go 30C - just to keep life time up really. Right now you can get some good deals on the older generation 30C packs - though they lack the high charge rate abilities of the newer cells.
