We Upgraded Our Boat to Lithium

Living on a boat has made us very aware of power usage. Our boat mostly runs on 12V power – lights, fans, water pumps, instruments – which comes from batteries on the boat. In this post, I’ll detail why and how we upgraded our boat to lithium batteries. We think it’s a good decision.

Rules of Batteries

Batteries on a boat are challenging. There’s all sorts of rules on things you should and should not do with traditional boat batteries. The main rules as we understand them:

  • Replace them all at once
  • Never let them go below 50% charge
  • Make sure they are all the same type and brand

It goes on. But the world of batteries is changing rapidly with innovation going on in other industries finding its way into the world of boats. The new technology uses Lithium Ion and is far more efficient and takes up far less space.

Bocas del Toro Boat Life

We’re in our second month in the archipelago of Bocas del Toro, Panama. Time is flying! We’re keeping busy, seeing the sights, and spending time with fellow cruisers. Here’s an overview of Bocas del Toro boat life.

About Bocas del Toro

Bocas del Toro (or Bocas, familiarly) is a province on the Caribbean side of Panama. Part of it is located on the mainland, but the important part is the chain of islands. Bocas del Toro means Mouth of the Bull, and the island chain has 3 big islands and many smaller islets and atolls.

Bocas del Toro is a popular tourist destination, and the site of many banana plantations. It has an airport, with several daily flights from Panama City, and multiple water ferries and taxis from the mainland.

There are three big islands in Bocas del Toro, where most of the activity happens and the majority of people live and work.

Isla Colon

Isla Colon is the main island, with the airport and main town, called Bocas Town. That’s where the stores are and lots of hotels and resorts. It’s the “big island” where we go to provision at the supermarkets.

Isla Carenero

Right across from Isla Colon, Carenero has a small marina, and many resorts, beaches, and restaurants.

Getting better on Sava

A couple weeks ago we posted about the issues on Sava. Overheating engine, freezer not working, Domino, battery challenges, and more.  And that was before we hit our lowest point yet with the electric head!

Well, we have good news: things are looking up right now.

The Engine

When we were in Tortola we hired a diesel mechanic, Wilbert, from Parts and Power. Wilbert and I worked for three days to diagnose and fix the overheating problems. We systematically went through the whole raw water coolant system and discovered that the pipe that fed water through the transmission was almost completely clogged. Three days of hard work later we cleaned it up and replumbed the system to prevent the clogging in the future.
