Redodo 12V 100Ah Review: Best Budget Lithium Battery for Boats & Trolling Motors

Why I Recommend the Redodo 12V 100Ah LiFePO₄ Battery for Boats & Trolling Motors

Redodo 12v Trolling Motor Battery

After spending years on the water and testing all kinds of marine batteries—from traditional lead-acid to higher-end lithium options—I can confidently say that the Redodo 12V 100Ah LiFePO₄ Lithium Battery is one of the best budget lithium batteries available today for boating applications.

Whether you’re powering a trolling motor, electronics, or just need dependable juice on the water, this battery hits the sweet spot between price and performance. I’ve been running it on my boat for a while now, and it has far exceeded expectations.

Why I Made the Switch to Lithium

If you're still using lead-acid batteries for your marine setup, you're missing out. Lithium batteries are lighter, last longer, and provide much more consistent power. But let’s be honest—quality lithium batteries aren’t cheap.

That’s where Redodo comes in. When I first came across the Redodo 12V 100Ah, I was skeptical. It was priced like a budget battery, but the specs and build quality told a different story. So, I put it to the test.

What Makes This Battery a Winner

Here’s what stood out to me after hands-on use:

  • Lightweight: At just around 25 pounds, it’s a fraction of the weight of my old AGM battery. That matters when you're trying to trim down boat weight.

  • Long-Lasting Power: I’m getting full-day performance running my trolling motor, sonar, and sound system —no voltage dips, no worries.

  • 4,000+ Charge Cycles: Redodo advertises 10+ years of life. That’s a huge win for anyone looking to get the most out of their investment.

  • Built-In Battery Management System (BMS): Overcharge, over-discharge, short-circuit, and temp protection—Redodo has safety locked down.

Lithium to Lead Acid Comparison

On-the-Water Performance

I’ve run this battery hard—saltwater and freshwater environments, long fishing days, unexpected weather—and it’s never let me down. For those wondering if this is a true trolling motor battery, I’ve used three on a 36V Minn Kota and they perform flawlessly.

This is especially useful for boaters who want a reliable power source for long trips. If you're trying to power your electronics and your motor off the same battery, this one delivers without blinking.

Best Budget Lithium Battery? I Think So.

For those of you looking for the best budget lithium battery for boats, this is it. It's also perfect if you're looking for an affordable trolling motor battery without sacrificing safety, performance, or reliability.

You’ll pay more upfront than a standard battery—but the lifespan, efficiency, and peace of mind make it a smarter long-term investment. Plus, you’ll never go back to lead-acid once you’ve seen how well lithium performs.
