As a matter of interest can anyone recommend a suitable/good external battery power supply to be used outside the GPS unit where the aircraft has no on board power socket and such that the GPS batteries inside the unit then become back ups to the external one? I am aware that some people use sealed lead acid or Lithium ion batteries for this purpose.
What size batteries offer the best endurance, useful life and capacity? Weight is an issue with SLA batteries and some saythat lithiums present a fire risk.
