Lithium battery mistakes people make

In this video report by Practical Sailor, editor Tim Labute provides a reality check about lithium batteries:

Lithium batteries are one of the most popular sailboat upgrades today—but they’re also one of the most misunderstood. In this episode, we break down the three biggest mistakes sailors make when installing lithium batteries on sailboats, and why these errors can lead to damaged alternators, shortened battery life, and unexpected electrical failures.

This is not a lithium sales pitch. It’s a reality check.

We cover:
• Why lithium batteries are not a drop-in replacement for lead-acid or AGM battery
• How lithium charging can silently destroy alternators and regulators
• Why cold-weather charging permanently damages lithium batteries
• The truth about Battery Management Systems (BMS) and what they really protect
• When lithium makes sense—and when it absolutely doesn’t

If you’re considering a lithium upgrade, already have lithium on your boat, or are trying to decide between lithium and AGM, this video will help you avoid expensive mistakes and design a safer, more reliable electrical system.
