Price is shipping included.
It also decharges at a miliamp/hour at your choice.
can also charge li-poly, li-ion, lead acid, but the charger is 0.06v off even after voltage correction , so not recommended for charging li-polys (check this thread
http://www.dealextreme.com/forums/Fo...hreadid.139845 for more info)
It can decharge and charge a battery, and tell how much miliamps it drained and could charge back to the battery, so you can know if the battery is dying or not.
It's really good for ni-mh, ni-cd, with shipping included 50$ price, definitely beats any charger in my city.
Btw i use one.
