Hey thanks guys. The parts I'm looking at are listed below. I'm wondering if there is actually anything that converts 115VAC (output from the power inverter) to 115VDC. Or is there an inherent loss of voltage when you go from AC to DC? I can't find anything that goes 115VAC to 115VDC. I just assumed the motor runs off DC, but do you think the "115V" description in the motor actually means 115VAC, and then convert that to DC, which will be lower voltage (max DC voltage I find in off-the-shelf converters is 42VDC)? Thanks again.

Hi there! I'm wondering where I could get a transformer to step up 12V DC to 115V DC. I can't seem to find anything off-the-shelf, and I don't think I have the ability/expertise to make my own. I'm planning to power a set of 4 115V DC motors with a 12V lead-acid battery. BTW as a rough estimate, a 12V 7Ah motorcycle battery should be able to power 4 25W 115V motors for 7*115/25/4 = 8 hours right (assuming voltage was stepped up so it could actually run the motor)? Thanks!
