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.

    Amazing! Fixed my issue after upgrading cart

    I added a 3rd battery. And 10amp solar charger with 200 watt flexible panel. I’m getting 100 miles on flat land around the lake at 8000 feet.

    Cart is super light now! Faster acceleration and top speed with a 300 amp controller upgrade.

    Finally the power I needed. Goodbye Lead Acid!

    Had been searching for a solution to constantly replacing LA. We have a cart at the coast that only sees action in the summer months. Tried everything to keep float charged and prolong life but would always fail. With a big motor and controller it wouldn’t take much to have a problem. Put these boys in and had to let off the pedal as carts weren’t designed to go that fast. 😂. Only time will tell about the longevity but so customer service has been excellent. Pleased with the quality and function not to mention fast shipping!
