Note: I know the audio is low, sorry. I'll check that for the next video.
This video goes into more detail on the battery that we'll be building. It covers why it's designed the way it is and, at a high level, what the various parts will do.

![Wiring The Boat For International Travel - Ep. 114
To travel the world, I need to be able to plug the boat into international power grids.
In this video, I cover installing a Victron auto-voltage 3600w isolation transformer (ITR3600) and the Victron Multiplus-II 48/5000/70 inverter charger.
Its nice to be working on the boat again!

Its time to move on to the Helm development! Before that can start though, I need to tie up a bunch of loose ends (and provide a bit of an update).

![This Can Save Your Life; ELCI/RCBO RCDs - Ep. 113
ELCIs, Equipment Leakage Circuit Interrupters, have been required on boats in North America by ABYC since 2013. They can prevent electric shocks on the boat, as well as prevent ESD, electric shock drowning. These should be retrofitted on to older boats, like mine.
This video attempts to set aside the emotions of ESD and instead explain the physics and biology of what leakage current is, how it causes death, and how an ELCI residual current device can protect you and others from drowning or heart attacks.
