LiPo education?

Hi everyone- can someone point to a resource that would provide an education to a non-RC hobbyist on spec'ing and buying LiPo cells and chargers for powering rocket electronics? I've googled around, and have not had much luck- the hobby shop sites assume too much prior knowledge.
I want to power an eggtimer and dual deploy, and an eggfinder (separately). I know Cris recommends 2S cells, but that's greek to me! Have found some online, but they are all over the map in price, and the chargers aren't seemingly packaged together.

Thanks in advance!

I would avoid the ultra cheap ones. lipos had (and the cheap ones still do) have a habit of going up in flames. There are places that sell flame proof bags to recharge lipos for that reason. The more established companys that make them have got the flambey issues taken care of. the 2 cell indicates the size which also indicate the power.. As say 2 D batteries produce twice the power of one 1S, 2S and 3S, can make the same voltage but the 2S and 3S makes more amps and run longer. When looking at chargers with more then one cell you will need a balancing charger (all types will need to be lipo chargers). As if the 2 or more cells charge at different rates that could cause more problems.I could go alot more in depth but in a nut shell this is what you need to look at.

https://www.rchelicopterfun.com/rc-lipo-batteries.html is where I read up on the tech prior to getting a 2s 130mAh battery. It is good at not assuming prior knowledge

Thanks guys, very helpful! I don't fly as often as I'd like, so the storage rules for LiPos is a bit intimidating. I would hate to lose a battery before flying it twice! Am I being too cautious or should I stick with alkaline batteries?

If you are not going to need it very often I would go alkaline. When you figure the cost of battery and charger, disposable is in my opinion the way to go.
