Eliminating the engine-driven aspect of an electrical system simplifies it greatly, but there are still a few things to consider. I'd love to hear from folks with more knowledge and experience on these notions and questions:


  1. What about using a mechanical battery disconnect switch as the "master" either within reach if the battery is located within reach? If key-operated it could be used to secure the system when not in use.
  2. Or, if the battery is farther away, how about one with operated by a push/pull rod or cable?
  3. Should there be a fuse or circuit-breaker right at the battery in case of a catastrophic short-circuit?
  4. Any strong opinions on integrated switches-circuit breakers vs. separate switches and breakers vs. separate switches and fuses?
  5. There are likely to be a few other items powered by the battery (12v gauges, maybe a radio or an anti-collision light), any special do and don't considerations when wiring those?
  6. In some designs including the VP-1 and VP-2 the fuel is very close at hand. Any special considerations for reducing fire danger with this kind of setup?

Cheers,

Matthew
