Posted by Matt Pierce on July 8, 2025 Powering Confidence on Every Kokanee Trip Fishing boats have come a long way—and so has the power demand that comes with them. On my boat, I run a full suite of electronics and gear: four electric Cannon downriggers, two Garmin fish finders, a Humminbird unit, Garmin Livescope, livewell, bilge pumps, stereo, navigation lights, and more. Add in my electric trolling motor—which I love for being quiet, clean, and low-maintenance—and it's clear: everything depends on reliable battery power. When my system runs smoothly, it’s a dream. But when the batteries fall short, the entire day on the water suffers. That’s why, a few seasons ago, I began transitioning to lithium power. Lithium Proven: My First Switch In 2022, I replaced the AGM batteries on my trolling motor with lithium. Historically, I’d only get about three seasons of use out of my AGM batteries before their runtime would start to degrade significantly—and it would be time to start shopping for replacements. Now, in my fourth season with lithium, I’m still getting twice the runtime compared to when the AGMs were new, and there's been no noticeable drop in performance. That change alone made me a believer. But I knew I’d eventually have to upgrade my starting batteries too—the same ones that also power all my electronics. At the time, there weren’t many lithium options that could serve both purposes: cranking a large outboard and supporting deep-cycle electronics throughout a full day. The Breaking Point: More Electronics, More Draw This past season, I added Garmin Livescope and another fishfinder to the boat. That pushed my system over the edge. I started noticing issues with image quality, and after some testing, I traced the problem to voltage dips—dropping below 12V and causing unstable performance. Even with two Group 31 AGM batteries, split between devices, my electronics couldn’t keep up on long fishing days. I'd find myself starting the motor just to get a recharge mid-trip. That’s when I decided: no more power issues. Enter Wattcycle After researching several marine lithium options, I decided on the Wattcycle 12 V, 100 Ah, 1200 CCA marine cranking battery for my new setup. Wattcycle stood out to me because it checked every box on my list—enough cranking power for my Verado 350, the deep-cycle capacity I needed, Bluetooth monitoring, and being able to be recharged on the water by my main motor alternator. It also meets Mercury’s published requirements for lithium compatibility. At the time of writing, I’ve just installed the Wattcycle battery and am preparing for full testing during my upcoming fishing trips. I’ll be tracking performance, voltage stability, and on water charging, and I’ll be posting updates here on the blog and over on my YouTube channel. If you’re considering a lithium upgrade, follow along to see how it performs in real-world conditions.
