I would find an electric motor repair shop near you and ask if they can convert it to 12 volts. Also send an email to Wearen and ask them about converting to 12 volts.I was trying to get the specs on this winch and how good they were, and if it could be converted to 12 volt if it is worth the effort?
Yes this. Run 2 batteries. You can still charge them using 12v.If it was me, I would buy two Duracell marine batteires for $220, hook it up, and use it. Then if it worked well, then figure out the charging solution. Probably mount he batteries in the bed or under it.
