Charging batteries fast has all kinds of benefits: less engine wear, fuel savings, less carbon. But how far can we go?

Selecting battery master switches and deciding how to wire them is a fundamental part of a good cruising live-aboard electrical system.

Most production boats have battery boxes that are nowhere near strong enough for use on an offshore boat. Let’s fix that.

Just because the battery-supplied systems on cruising boats are low voltage, that does not make them safe. Here are some tips to reduce the chances of a nasty injury.

Lithium batteries have many benefits, but are too complicated and fragile, and not fault tolerant enough, to be relied upon exclusively on an offshore boat. Here’s how to fix that.

Load dumps on a cruising boat are dangerous. Here’s how to prevent them, including some special tips for “drop in” owners.

Load dumps are an intrinsic danger with lithium batteries installed on cruising boats. Here’s why, and why we need to fix it.

It’s a common misconception that battery-supplied electrical systems are safe because they are low voltage. That’s wrong. In fact, there are high fire risks. Here’s why, and what to do about it.

Most production cruising boats are fitted with inadequate DC electrical systems. Let’s fix that.
