are there chargers that charge batteries faster ? mine takes 1.5hr to 2 hr to charge my 11.1v 1300mah Li-po - what specs for chargers should i be looking at ?

what numbers on batteries determine amount of flight time you'll get ?? ex; 11.1v 1300mah Li-p0, is it the mah or volts ?


whats the best to take out to the field - car battery, extra batteries ???


thanks
