Q and A
I have had some questions on various parts of the ghost, so I thought I would give some answers. Relay, Main Contactor: For some reason these are open air contactors. The new one is sealed. I do not know why they are called contactors when they are just big relays! These can be completely disassembled with a screwdriver. Normally I wouldn't want to take these apart, but I was having problems and had nothing to loose by attempting a fix. What is odd is that the relay still opened and closed. And even at 500 amps it had near zero voltage across the contacts (after I cleaned it up). There may have been a partial short in the coil that was causing an over current fault. I am told this has been known to happen. Battery Charge Voltage I am using Lithium Iron Phosphate batteries. These are very similar to Lithium Ion, but are much safer with the trade off of lower cost and slightly lower energy density. Because of the different chemistry, they will have a different charge a
