I noticed when I charge my 2s 7.4v 5000 40c lipo that the meter that shows the charging voltage sometimes goes as high as 8 volts while its charging. Is this normal for a 7.4v lipo?

I figured it out. Sorry im new to lipo

Spend a few min and read up about lipos - this will answer a lot of questions -

Duster, that was a great link, thanks.

I'm returning into TC after about 4-5 years break, so this was a good kickstart on LiPo's :-)

Look around - they have a decent article on lipo chargers and charging lipos in parallel - all from the plane heli perspective, but still lots you can learn.
