EPOCH LIFEPO4 TECHNOLOGY
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.

EXCELLENT better than I expected
- John T.Verified BuyerRated 4 out of 5 stars1 week ago120ah the way to go
Attempted to run our cart with 60ah. Was getting numerous errors and only 50% battery usage. Added another 60ah and all issues have gone away. Love the range and power. Should have installed 120ah system right from the start.
- Roberta H.Verified BuyerRated 5 out of 5 stars1 month agoGetting more power for my golf cart
We already had 2 batteries for our golf cart and needed to add another one according to one of the guys I talked with. It has made a world of difference in having more power and I actually think the batteries last longer between charges. I must say any time I have called the gentlemen I talked to has been very helpful and are quite knowledgeable.

- David V.Verified BuyerRated 4 out of 5 stars1 month ago2016 RXV 4th battery purchase
(2016 EZGO RXV) I originally bought the 3 battery 90Ah kit but since I live in a hilly PNW neighborhood I was having major issues with overpower the BMS going down a hill on a full charge. (batteries shut down and cart starts freewheeling with no brakes...family freaked out). Talked to Jim and he advised to add a 4th battery which ups the overcharge threshold to 240Amps. So far I still see alarm 4 on long uphill pull but I can deal with that. Have not had issue on overpower going downhill. Bottom line is that if you have a RXV and you live in a hilly neighborhood 4 battery 120Ah config is a MUST!! RXV is a tight fit and a little tricky to mount Busbars. Still working on that. Right now running all to battery directly which is not ideal. Support (Jim and co) is awesome, 4 stars since I am still seeing Alarm 4 uphill with 2 people in cart.
