hey guys....how long do it take to fully charge a li-polymer battery (11.1v 1800mah 12c) ??????
tks.

Charging at 1C, I guess mine takes a little over an hour (rough guess but it sounds about right).

tks codepunk......another question if you allow me to. Is there any problem if it stay charging for more then one hr? and what battery would you suggest me to buy for my t-rex se? tks once again

over charging a lipo is very bad,unless you want to burn your house down then its allright.get a decent charger that will signal you when it is done. it is worth the money.

my Blade CX 7.4 V takes about an hour
Just be pateint. Otherwise you could end up with less fly-time like I first did!
