Now the trouble is how to build a high voltage cutoff for the solar panel so I can't overcharge. (and no I don't want a 60amp 120v MPPT charger that uses half an amp to handle my 1 amp panel trickle charging my batteries)
Cheers

Here's the charge controller I am using with my Kaneka 60watt panel:
Xantrex C40 Charge Controller
Since it's only one amp, you may not really need a controller - It would take 100 hours to recharge a 100 amp hour 48V pack..... Just let it pump.
If you plan to leave the vehicle in the sun for days at a time with the solar running, I suppose you should have something. The trouble with those Kaneka panels is that you can't use cheap 12v accessories with them!
