Very good R/C battery sites

[darren_uk]

I've just been doing some battery research and come across this very good site.

Moderators: Perhaps this thread can be made "sticky" and others can add their useful battery sites too?

I just bought 4 batteries from helidirect and am thrilled with the performance and price.
The 2200 MaH 12-c E-Flight batteries are 38 bucks and perform as well as my Thunder Power 2200 MaH lipo pack that cost 90 bucks for only one of them. The E-Sky 2-3 cell balance chargers work "OK" the price is 9.99, but I got two of them for backups, I use the higher dollar E-Sky 2-4c Lipo charger and they work great for 29.99 each, my battery collection is about 12 lipo packs and 6 chargers and RISING . I hate charging out on the feild, I want to fly 6 hours and not worry about charging wile I fly, Thats what monday nights and Budweiser where invented for
I store them in a "Home Land Security" fire box I bought from Walmart, to
many accidents are popping up out here at the local fields due to the onset of HOT weather, I tell ya only one of these packs blowing out on you will turn your whole truck into a cinder of ash. The fire ball is big and violent. The temprature difference between 60 degrees and dry compaired to a hot 95 degree day and humid can be curtains for your batteries.
I fly 8 minutes and land regardless of how much power is left on the battery pack.

Week number 3 and so far so good , these E-Flight 2200 12C batteries are performing over my anticipated thoughts on performance.

epower batteries
only cause their quality and the charger that is great is only 10 bucks
makeing it the cheapest grade a quality for battery packs
they even have 3s 1000mah to 3s 2200 mah to 4s very cheap.
instead of buying a 70 buck batt
then a 60 buck tritron charger or something of that sort.
www.helidirect.com
or www.ehirobo.com
id be careful of ehirobo.com people say they are bad. ive had 6 purchases...no problems.

I bought them because occasionally I like to gamble so what the heck.
To my UN-EXPECTED surprise they perform way better then I expected them to, I figured for 12 c rateing they would be indoor testing, scale flying slugs.
But NOPE, the 3 d mode shows no less power in performance then my Thunder Power 2200 MaH 16c battery pack. And no loss in flight time.
I think some of these guys claiming anything over 15 c rateing discharge need to be lab tested and proven it's not all hipe?
Now the real test of the deal is= HOW LONG WILL THESE LAST. Time will only tell. The thunder Power is well over 100 recharges and showing no signs of weakening, I am not expecting the same results with the 38 dollar deal.
