Battery Questions please help
 
OK I got some more Questions I purchases my corona :D(it is in the mail) with a atomic force motor and a phoenix 35 ecs Now I need to get batteries I have been hearing great things about lithium batteries but I don’t know what I need for this set up.:( So what voltage do I need? What about the amperage? Most of the websites with litho for sale don’t mention amps just volts so does that mean I shouldn’t worry about it? I want something with good power and long flight time (yea I know I want it all) I really want to use lithium because eventually I will be switching to a brush less set up so I want to purchase only one charger and get longer flight time with my brushed motor for now. Anyone got any advice for me?

you need a lithium pack that can handle at least 20amps I would go with one that handles 30 just to play it safe.irate lithium packs are good so are tanic packs, also thunder power. I would recommend a 3s2p pack or maybe even just 2s2p with a little less power.flight times will be around 22-40 min.

I hope you didn't get a phoenix 35 with your atomic force - the phoenix is a brushless controller. You need a pegasus 35 with your atomic force.

Ok so now that we have established that it is in fact a Pegasus ecs what voltage will the atomic force handle? Given the weight of current nimah packs couldn't I get a lithium pack with 3s4p and have super long flight times (that is if my figuring is right that the cells in parallel ad to the duration) given that lithium cells weigh much less?
