Hello fellow Evlist users, I have question around charging the battery pack on an EV from a larger pack of batteries, same voltage. I'm looking to build a stationary solar array (48v) and charging 12 x 12 volt 133 amp/hr sealed lead acid batteries, 4 batteries per bank These are retired but gently used UPS batteries and I will have about 1200 watts in solar going into a Morningstar 45 amp solar controller. I would like to be able to charge my EV boat pack (http://www.evalbum.com/4767) from this pack, UPS batteries again, but 4 x 12 volt AGM 133 amp/hr. My questions for the list: how do I transfer the charge from the solar bank to the EV pack? Can I just use a charge cable directly and the two banks will equalize? Or would I need to use a charge controller? I have another 45 amp solar controller I could hook from the main battery pack to the EV pack but I fear the input amps would exceed it? I remember a while back someone mentioned they were charging a lawnmower from a truck pack, wish I could find more info on this.
Thanks in advance for your help and thanks for all the great contributors on the list, fantastic learning and information!
