At Epoch Batteries, we are proud to offer our customers the highest quality lithium iron phosphate (LiFePO4) batteries for marine applications. Our batteries have been specifically designed and engineered to meet the demanding needs of the marine industry, providing superior performance, safety, and longevity.

One of the key advantages of our LiFePO4 batteries is their exceptional safety. Our batteries have built-in protection circuits that prevent overcharging and over-discharging, greatly reducing the risk of fires or explosions. Additionally, our batteries have a high thermal stability, which means they can withstand high temperatures without catching fire. This makes them the perfect choice for marine applications where a high level of safety is required.

Another advantage of our LiFePO4 batteries is their long lifespan. Our batteries have a cycle life of up to 3,500 cycles at 80% depth of discharge, which is much longer than traditional lead-acid batteries and other lithium-ion batteries. This means that they need to be replaced less often, saving our customers money and time in the long run.

Our LiFePO4 batteries also have a higher energy density than lead-acid batteries, which means they can store more energy in a smaller space. This is particularly useful for marine applications where space is often limited. They also have a lower weight than lead-acid batteries, which makes them easier to handle and install.

Our LiFePO4 batteries also have a much wider operating temperature range than lead-acid batteries, which means they can be used in a variety of different environments. They can also be discharged to a much lower level than lead-acid batteries without damaging them, which means they can be used more efficiently.

Our LiFePO4 batteries also have a faster charging time than lead-acid batteries, which means they can be recharged more quickly and can be used more frequently. They also have a low self-discharge rate, which means they can be stored for longer periods of time without losing their charge. This is particularly useful for marine applications where the battery may not be used for long periods of time.

At Epoch Batteries, we are committed to providing our customers with the best possible products and services. We are confident that our LiFePO4 batteries are the best choice for marine applications and stand behind them with a comprehensive warranty.

    24V100Ah Battery and Charger

    I give them “6 Stars”! I received the battery and charger in just a few days and was kept well informed of its progress. Unfortunately the included volt meter was damaged, I called and spoke with Jamie and described the problem. In less than 5 minutes I received a confirmation that a new meter was shipped and it arrived in about three days. A follow up call from Kevin came to ensure I was satisfied and all was good.

    I won’t be using the battery until this spring and review it then but for now it is very refreshing to deal with a company that stands behind their product and provides such great customer service. Downloaded the battery app and it worked good. Took a little playing around to get the Bluetooth working but finally had success and all is good. Thank You Epoch

    Nice Battery!

    I received the battery in timely fashion, well packaged, and as viewed on website. My initial impression ,out of box, the battery was one of good quality, design and durability as relates to its construction. I was very impressed and appreciative of the u tube video of deconstructing and testing of internal components of this battery, as well as 10% discount code as well, thank you. This is my fist LiPO4 battery purchase to go along with the install/upgrade 80fp 24v Terrova trolling motor for my boat. Thanks to Kevin for answering my questions and his follow up email on charging extension for the battery. In this day and age of internet commerce, speaking with someone who’s knowledgeable about the product is refreshing and ultimately allowed a sense confidence to surpass my hesitation/concern/anxiety of such significant purchase online.

    Upon install, I did discover 2 minor issues. Fist thing, was cap covering the plug for the included charging indicator was cross threaded, bummer! A simple suggestion would be to use coarse thread rather than fine plastic threads on the assembly. Secondly, upon removing from plastic bag, the charging indicator itself, had 2 of 4 screws on the face plate were over torqued and broke off, bummer again! Well, this was an easy fix with 2 small drops of JB weld. I feel that both of these issues should have been discovered on a quality inspection prior to packaging and shipping to seller. Anyways I didn’t feel this warranted a return.
