Explore the Benefits of Lithium Batteries

Compared to lead-acid and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including improved discharge and charge efficiency, longer life span and the ability to deep cycle while maintaining power. LiFePO4 batteries often come with a higher price tag, but a much better cost over the life of the product. No maintenance and super long life make them a worthwhile investment and a smart long-term solution.


Inherently safe chemistry. BMS provides extra protection.

Drop-in Replacement

Available in standard industry sizes.


50-60% less weight than lead-acid equivalent.

Longest Life

Up to 10X longer cycle life than lead-acid equivalent.

Charging - Fast & Safe

Highly efficient charging. Can fully charge in 1-3 hours. Built-in overcharge protection.

PSOC Tolerant

No damage from partial state of charge operation or storage.

Long Shelf Life

Low self-discharge so the battery maintains state of charge.

Maintenance Free

Plug, play and charge. No watering.


No gasses emitted.



Lithium is Long-Lasting

RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of rated capacity after 2,000 cycles. Most lithium-ion batteries last five years or more. The average lead-acid battery lasts just two years. Lead-acid batteries also need to be maintained, requiring water replacement to avoid structural damage; if they aren’t maintained properly, their life span is shortened even further. Because lithium batteries require no active maintenance, a one-time purchase guarantees longevity.


Lithium is Quick & Efficient

Lithium can charge and discharge at a high rate providing maximum versatility for all types of applications. Fast charging minimizes downtime, and lithium’s high rate of discharge is perfect for a burst of power. Lead-acid batteries must be charged in stages over a longer time, and they perform inefficiently during high discharge periods, making them less versatile than their lithium counterparts. Lithium’s efficiency is unparalleled, especially under high-stress situations. Unlike lead-acid, temperature fluctuations and energy depletion barely affect lithium’s power delivery. Lithium is the logical choice for applications that will exhaust the batteries or run in extreme weather.


Lithium is the Lightweight Champ

RELiON LiFePO4 batteries provide more energy than lead-acid batteries and are typically half the mass, reducing concerns about battery weight. Compared to other battery chemistries, lithium provides the same or greater energy at less than half the weight and size. This means more flexibility and easier installation!

Why They Made the Switch to Lithium

"We were draining our 6V Trojan lead acid wet cell batteries down too quickly. Lead acid batteries are only supposed to be drained down to 50%, but we were finding that, especially in the winter time, we were draining our old batteries far past that, which damaged the batteries. We just didn’t have enough power or storage capacity. After ten years of living in our trailer, we wanted to live a more comfortable, normal life and use some real appliances, like a toaster, a blender and an espresso machine."

Power On the Tournament Trail

"I have seen multiple anglers have their batteries die on them during a tournament, including other lithium battery brands. That was just further validation that I made the best choice possible. I never have to worry about running out of power and having to head out early from a tournament to recharge my batteries anymore. I’m able to spend more time on the water - both while practicing and during tournaments - with no power loss. I understand now why so many professional anglers have already made the switch to RELiON batteries, as they provide a solid competitive edge.

Lead is Dead

It doesn’t take much to significantly reduce the life of lead-acid batteries, no matter how diligent you are at taking care of them. There are several causes of premature lead-acid battery failure. Discover what they are in this two-part Tech Tuesday Series.
