[QUOTE="Al U Minium, post: 423216, member: 20945"] 48 volts DC can be very dangerous. We numb around with 12 and sometimes 24VDC so when the voltage goes higher so does the chance for severe burns and even death. It only takes 0.1 amps to stop the human heart. Break the skin in a cut and a 9vdc battery can kill you. If you short out 36-48VDC the sparks can be just like an arc welder. Make it as safe as you can: Use only pressure type connectors - no solder Keep batteries in non conductive battery boxes with secure covers Use fuses in non corroding heavy duty fuse holders Circuit breakers are less reliable at DC in preventing arc over Never reach across battery terminals or connectors with body parts Don't mix lights and electronics with your motor batteries Buy a really good quality main power switch rated for the DC Voltage and able to stop an arc flash over from a short in the system Turn it on only when running the motor Do not try to make any repairs while under way or while the boat is in the water Electric can be safe and quiet, but please don't cut corners with this set up [/QUOTE]
