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.

- Thomas C.Verified BuyerRated 5 out of 5 stars12 seconds agoGreat Kit
Really nice and complete kit, so far I am impressed with the results.
- Clint P.Verified BuyerRated 5 out of 5 stars2 weeks agoSo far, so great.
Took me a while to install under the cockpit of my 1968 Bristol 27 Weekender.
The kit is very well thought out, and only missing custom items I needed: Breakers, switches, intermediate bus bars, battery cable extensions.
One complaint: The parallel bus bar can be a real pain. Its bus bar plates come off along with the safety covers. This is just a nuisance when assembling, adjusting and tightening the connections. But it occurs to me it could be exceptionally dangerous if the power is on and someone decides to pull off the covers for some reason. I left the cover off the ground side because it’s maddening getting at it blind from the cockpit, through the locker, and underneath the deck. It was annoying enough out in the open during bench assembly and test.
Just completed a commissioning run. About 3 nm down the creek to the bay and the same distance back, running for nearly 2 hours and at 3-4 knots, of course. Afterwards, 55% remaining of a 120Ah charge. Pretty much much as expected. Hull speed is only 6 knots, and not worth blowing all the charge in an hour to run that fast.
- John P.Verified BuyerRated 4 out of 5 stars3 weeks agoGreat....Better by skilled in DIY. Include Instructions.
First of all, the experience has been great. I was shocked that no instructions for the installation were included. (Hence the 4 stars) I did find that once I was able to get everything figured out via YouTube videos, it worked quite well, and I should say very well. The Bluetooth app is very detailed and effective. Again, I had to go to the Facebook help group to find the password to make a change on the app. (Hence the 4 stars) Overall, this system is superior to the Lifepo4 system I had three years ago. I recommend the system but you should expect to be a good DIY person and get on the Facebook page for help.
