Here we go again...... (probably going to get tons of replies)
If you have a charger that has the proper LiPo profile (cc/cv) then it will set it for you by way of what you input for the capacity (mah) and number of cells/voltage. The charger will start at 1amp for every 1000mah of the battery, what is referred to as 1c (5000mah starts at 5amps). As the charger gets close to sensing a peak voltage, it steps down the amps until its done.
That pretty much it... so it should be pretty easy.
