Pat,
Thank you for bringing this up. This may be a case of the smart charger being too smart. A battery under load could easily lead the charger to see a "damaged" battery, and better programming would shut things down before more damage occured.
Your suggestion of a simple power supply is excellent, I don't think that I've read a post here that has specifically made that suggestion. Do you know of any 1000W to 1500W 48V power supplies that are available to DIY folks like us?
Thanks,
Eric

I don't think the problem is one of overheating that was mentioned earlier. It is that the dual pro was designed as a battery charger. It has microprocessors that monitor the batteries. A motor drawing 15 amps at 48 volts does *not* look like a healthy battery to the microprocessors. The dual pro will shut down with an error because it is not making any progress charging the batteries. It knows something is wrong. If you want to run your motor from a 48 volt power supply, I recommend buying one rather than using a charger.
