Default lipo help

I got a few zippy 350mah 2s batterys and i must be doing something wrong charging because I'm only getting about 2 minutes of runtime. I put them on my thunder ac6 charger and put it on balance charge and it went to 7.4v everytime i tried. I tried disharging them first too. Is 6v as low as i should discharge them too?

A full charge for a 2S lipo is 8.4V, or 4.2V per cell. You should never discharge the battery below 3.2V per cell, or 6.4V total. 6V is too low and can damage the battery.

as a rule of thumb you charge in milliamps what the mAh rating is, so a 350 mAh battery like yours can be charged at 350 milliamps. or 0.35 amps. Charging at 0.2 amps won't hurt anything, but it is slower than you need to be.

to get a full charge I always charge at a few MAH less than the battery is rated.
