Battery Monitors Frequently Asked Questions

Q. What does a battery monitor do on a boat?

A battery monitor tracks your battery’s voltage, state of charge, and power usage in real time, helping you understand how much power you have left and avoid unexpected battery drain.

Q. Do I need a battery monitor for my boat?

A battery monitor is highly recommended if you run electronics, trolling motors, or multiple batteries, as it gives you accurate information and helps prevent running out of power.

Q. What is the difference between a battery monitor and a voltmeter?

A voltmeter only shows voltage, while a battery monitor provides detailed information like state of charge, power consumption, and remaining battery life.

Q. Are battery monitors hard to install?

Most battery monitors require installing a shunt and connecting to your battery system, but many modern units are designed for straightforward installation with clear instructions.

Q. What features should I look for in a battery monitor?

Look for accurate state of charge tracking, easy-to-read displays, compatibility with your battery type, and optional Bluetooth connectivity for monitoring from your phone.

Q. What is the best battery monitor for marine use?

The best battery monitor for marine use is one that provides accurate real-time data, is compatible with your battery system, and is built to handle harsh marine environments.

Realized they were too small for Salmon fishing so we cut the hooks off & made them into nice earrings for my daughters - would sell like hotcakes @ Christmas

Harbour Chandler Nanaimo online and retail fishing and marins upplies

I first found this place in person when boating and at dock in Nanaimo. Great prices and staff then. I just placed 2 orders online. Very good prices compared to what I get here at retail stores in the lower mainland. Knowledgeable staff and placing my online orders. I’ll likely buy much of my gear in the future from them.

SIMRAD Halo 20 Radar
Replacing my 3G radar

In replacing my 3G radar, the entire process was easy- HC staff were extremely helpful throughout the process. From testing the old unit to identifying a 'plug and play replacement and required adapter, everyone was available and informative. I'm almost looking forward to the next foggy day.
