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.

    So far this has been great

    Owned for 1 month. It is way overpowered for what I need but it’s American designed and has good customer service(sent me wrong battery charger and got the new one sent to me right away). For the same price as Dakota lithium 60ah why not get extra 100ah epoch. Plus this battery has a heater, Dakota does not. I run a 36v Minnkota ulterra on a 20ft aluminum boat. Trolled around and Bass fished for 4 days straight and still have 38% battery left! A different trip I trolled non-stop all day at power level 3-5 and only used 30% of the battery. This thing is a beast. So far so good. Will be back and post if I have issues in the future.

    I’ve gone through 4 sets of lithium batteries and used other 24v lithiums. This 36v is the easiest and most convenient battery I’ve used yet and lasts a LONG time. I run my trolling motor on 3/4 speed for 4-8 hours at a time and I’ve never had the battery under 70% at the end of the day.

    36v EZ-GO

    Replaced the Lead-Acid batteries in our 36V EZ-Go golfcart with the Epoch 100AH battery. easy swap and it has been great so far. Taking the old battery's out and making a wood platform to mount the battery onto took as much time as installing the battery and wiring in the indicator.

    so glad to be done with watering the old batteries!

    it has great power, but I really haven't given it a thorough work out yet to see how its endurance is.
