Epoch Golf GC2 Quick Spec Sheet


At Epoch Batteries, we are excited to offer our customers top-of-the-line lithium iron phosphate (LiFePO4) batteries specifically designed for golf cart applications. Our batteries are engineered to meet the rigorous demands of the golf cart industry, providing exceptional performance, safety, and longevity.

Our LiFePO4 batteries boast outstanding safety features, including built-in protection circuits that prevent overcharging and over-discharging. These features greatly reduce the risk of fires or explosions, making them a reliable choice for golf cart applications where safety is paramount.

Our batteries are also known for their extended lifespan. With a cycle life of up to 4,000 cycles at 80% depth of discharge, they last significantly longer than traditional lead-acid batteries or other lithium-ion batteries. This longevity results in cost savings and reduced downtime for our customers.

Our LiFePO4 batteries are also ideal for golf cart applications due to their higher energy density, which enables them to store more energy in a smaller space. They are also lighter than lead-acid batteries, making them easier to handle and install in golf carts where space is limited.

Our batteries can also operate in a wider range of temperatures than lead-acid batteries, and they can be discharged more deeply without damage. This makes them more efficient for golf cart applications and suitable for use in different environments.

Our LiFePO4 batteries also feature fast charging times and a low self-discharge rate, allowing for more frequent use and longer storage times. With our comprehensive warranty, we stand behind the quality of our batteries and are dedicated to providing the best possible products and services to our customers in the golf cart industry.

    48V Lithium Battery Kit

    Followed directions given and installation was fairly simple. I did move a few things around and was able to fit it all on the battery compartment. Batteries seem to work as advertised so far. Definitely like not having to worry about the wet batteries! 2006 club car precedent. Upgraded D&D motor and 500A controller.

    I am mechanically declined but installing this kit has been pretty straight foward. In the two or three hiccups I had, a simple phone call to the company solved the problem. Kevin always greeted me ready to answer all my questions. I am very happy with the way it came put.

    I am having new motor and controller installed on my cart tomorrow so havent had a chance to use yet. Followed balance procedure and charged all to 100 percent. Had a question and was easy to get in touch with a helpful tech. Should get my cart back next week and really cant wait to check out performance

    So far so good!

    I installed two sets of the 120ah kits. One set went on a '07 Precedent and the other on a '15 Precedent. The '07 was a little more difficult due to the center console and limited space. My only frustration was the bus bars, voltage reducer, and charger were not the same as the picture on the website. I spent time prior to ordering the kit laying the project out based on the product description. I think when spending this much on a product you should receive what you see when you order. I have been happy with the performance. First trip out, I went 28 miles in the Texas hill country on some pretty steep climbs with four adults on the cart and still had 48% charge left when we stopped.
