Todd Battery Chargers [RE-wrenches]

Hi Scott and all,

In the electric vehicle conversion industry we use Todd chargers all

older Todds could take DC or AC input).  Because they were vibration 
and insect sensitive we blew alot of them up.  Below is a reference 
from that list from a few years back.  Email him -  I imagine he's
