Just got some new Gens Ace 5000mAh batteries to try out. The first time charging them (SkyRc Ultimate800 charger) they only charged to 2500mAh. Is this normal? My other two batteries go to their full capacity.

Edit: or maybe they were half charged when I got them? I also noticed the output charge lowers as the charge goes on.

Your "edit" is correct. They come with a partial charge on them. The LiPo charge sequence is start at the preset charge current (5A for example) and hold that current until the voltage reaches 8.4V (assuming a 2S pack). Then the charger holds the voltage at 8.4V and lowers the charge current until it reaches zero. This is known as CC-CV (Constant Current - Constant Voltage).

Thanks, that makes sense now. Still getting used to a charger that shows all this info
