Hmmm maybe not so smart.
I forgot to add that my battery bank has 150 amp hours in it so at 90% charge I have to still pump in about 15 amp hours. At about 500 milliamps an hour average it is about 30 hours. A single OEM battery has about 70-75 amp hour capacity and you will most likely be fully charged in less time (about 15 more hours).
