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.

    Good Purchase

    Well, I really don’t know where to start. Once I place the order, I had the new battery within 24 hours. I had to do some modifications to my boat to get the battery to fit. Nothing major. I ran the battery on Tuesday spot like all day with a 5 mile an hour wind. Only used one bar power. Today on Friday we had 11 mile an hour winds. Spot lock all day pass around the trolling motor at 10 in between spots. Got home today plugged in the meter only used three bars out of 10. This thing rocks. I’m also running the Dakota lithium. I’m also amazed at how much power I have left at the end of the day. I’m so glad I Purchased this battery. I’ve been telling all my friends how great it’s been. A couple things that would be really great. I love the plug-in meter however, I can’t use it because of the height between my deck. Where the meter plugs in could be offset an inch or two either way and not be centered so the strap could tie the battery down a little bit better. And overall I wish the case was just a little bit smaller. But my rating so far is outstanding. ……

    Mr. Gary Metz, owner of Paragon Home Builders

    I had them at the same voltage, then connected them in series to get 56 volts. Then the voltages changed, as much as 2 volts, later they went back to equal voltages. This is a new experience for me, should I be concerned? I would like 4 more, can I get the same price?

    Great batteries a couple of months in.

    These batteries have been great. From the extended use over agm and lead, to the battery meters I was able to mount up front of the boat.

    I run 3 of these batteries on a 36volt ulterra, fishing big water walleye tournaments in a 21 foot deep v boat. I have been impressed so far!

    I’d say that I average my motor setting in 4-5 and get about 10-12 hours of constant run time without any thought of battery reserve. If I was worried and did more to monitor, I could probably get 14-16 hours out of them. In comparison I would get 6-8 hours of usage from my agm batteries in the past.

    Can’t beat the price on monitorable (not a word) batteries. I’d have gone with the Bluetooth version but I didn’t have room. These batteries are comparable size wise to group 31s.

    Again, they have been great!
