Hey guys, I have this charger. http://www.evike.com/product_info.php?cPath=31_171&products_id=30777 a while back i realized that i charged it on LiFe and not LiPo. Sorry noob moment. anywho now my batteries dont even last 10 mags. is it because of how i charged it or because that charger isnt that good? the batteries were Turnigy 7.4 1200mah 20C batteries.
