How long about will a 2s 5000mah 7.4v take to charge?
45 minutes to an hour and 20 minutes depending on the charge level at the beginning and the condition of the pack. Assuming you charge at 5A.
This will TOTALLY work, saw a guy on YouTube do it
Also depends on your chargers capabilities. Say you have a cheap 1 amp balancer/charger then it will theoretically take 5 hours to charge a 5000 Mah battery but in real time it takes less because of the lipo cut off. With a good charger set at 5 amps then it will take an hour theoretically but in real time it will be less. (Mah of battery/Amp you charge at = theoretical time of charge)
