Charging at 1c with a good stable charger (I'm going on a limb and guessing your charging a multi cell LiPo battery) but should take about 1-1.5 hours at 1c charge rating. Also maybe longer if your charger does the balance charge for the last 10 or so % of the battery. Which is highly recommended you do
All depends on amp input
It can take up to 1-4 hours to fully charge depending on your amps.
Depends on the charger
