Hello

The internal mounted battery will keep an EFI alive for up to 2 hours but everything else goes black. Wanting to communicate, have tranponder output, and lights require more power. If the battery cable falls off or the alternator fails your lost!

A spill and leakproff motorcycle battery may do the job. People use a second alternator or starting battery as spares but they are heavy and take up alot of room. A new motorcycle battery would work. You can get them cheap and rated for any power you want.

Some EFIs give a prompt and time to go to stand by power. Engines with out mags require power to stay running.

So what are the thinkers doing?

By the way it's now 29 deg far with a high expected in the upper 40s but wind is 0 mph and I'm looking at that tacker sign that says we drink coffee so we can do stupid things faster!
