Si era bruciato il FET e rovinati i contatti meccanici, è stata un'operazione complessa, visto le dimensioni ridotte, ma alla fine ci sono riuscito a ripararlo! il guasto si è verificato prendendo un ferro dell'armatura durante un foro su un muro per uno stop, il bloccaggio probabilmente ha determinato un picco di corrente tale da rovinarlo, una bella soddisfazione !!! http://tinypic.com/view.php?pic=zrh4p&s=6 ------------------------------------------- Google Translate It was burned ruined the FET and mechanical contacts, has been a complex task, given the small size, but in the end I managed to fix it! the fault has occurred taking an iron armature during a hole on a wall to a stop, the locking probably has determined a peak current such as to ruin, a great satisfaction!

A123Systems after 2 years of life 2.3 Ah capacity tests OK internal cell resistance of 15 mohm to 33 mohm! compromised power drill! NICD forever! regards

big disappointment! :'( Dewalt that not only uses A123Systems

I think the maximum is currently A123System utensils, for discharge current and life cycles Sanyo UR18650ZT have the C = 2700mAh for a discharge current of 0.54 A which reduces to about "" "1800mah for discharge current of 5.4 A " "" " http://battery.sanyo.com/product/lithum-ion/pdf/01/UR18650ZT.pdf greetings
