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.

- Mark H.Verified BuyerRated 5 out of 5 stars2 months agoExpensive but worth it
The kit comes with everything you need to convert a Lead Acid Battery system over to LIFEPO Battery System. Every component included is of high quality.
- Curt G.Verified BuyerRated 5 out of 5 stars5 months agoGreat service
I love the batteries perfect for my setup I have a hisun sector e1 4x4 and doing great. Still giving 5 stars had one battery that hadca problem with it but they replaced it right away. Best customer service I've found in along time
- Ronnie R.Verified BuyerRated 5 out of 5 stars6 months agoPolaris Ranger EV upgrade done!
We bought 2 packages of six 48v Epoch batteries; each 6 pack for total of 180 Ah to install on Polaris Ranger EVs. My Ranger was 2008 model with eight 12v batteries (2 banks of 48v hooked in series) with 2 banks connected in parallel at the end before it goes to the controller. Charged each battery separately with supplied charger for about 1 hour each till fully charged before installation as recommended. I Put 3 batteries under the passenger seat and 3 under driver seat. Started parallel connections from front passenger side battery and ended on front driver side battery where we made the final controller connections, SOC meter and new charger connections. Removed the plastic battery tray, cleaned and painted metal battery support frame due to acid corrosion. Reused the battery plastic hold downs with new stainless steel rods since the factory ones were carbon steel and were corrected and some broke removing them ( mail ordered long 8Mx1.25 metric ones from Fastenal) and cut each in 3 ( each piece about 13” long) and metric nuts ( 2 nuts jammed on top of each rod). Also tapped the threaded metric hole on each hold down rods location on the battery trays to clean up threads. Used all 4 battery posts on each battery( did not use the supplied bus bar). Ran CANbus communication cables starting with front passenger side battery all the way around to final front battery on driver side. Needed a longer CANbus cable to jump over from one side to the other so had to call and order…
