48V 105Ah GEN3 Eco Thru Hole Battery Individual

Lithium upgrade for my 2019 Club Car Tempo

"Easy install with the provided instructions and YouTube videos. We ordered the full conversion kit minus the 12 volt convertor (already installed on cart). The Battery was a snap with the thru hole lock down design. We drilled a hole in the dash for the voltage gauge which made for a cleaner look instead of the optional mounting bracket. The Charger was a simple install once I realized cable (A-3351-060) is not used unless installing an optional lockout module. This info should be included with the charger so as not to confuse the installer. We like the improved cart performance and we will use these guys for our future tire and suspension upgrades. Overall I give it 5 stars!"

48V 105Ah Gen3 thru hole Icon Bundle

"Ryan was great in keeping me informed about delivery and sending me videos. The install was straight forward and it turned out great. If you are thinking about an upgrade for your cart, go ahead and pull the trigger. And definitely go with Eco lithium battery."

Great Product and Easy to Install

"I purchased the Eco Lithium battery bundle and it changed the performance and endurance of my 2024 ICON i40L golf cart! The installation was easy after watching one of the You Tube videos. Extreme Carts was great to deal with and I will use them again."

New Eco Battery

"The install was very straight forward and took just a few hours. The range distance compared to the lead acid is unbelievable. The biggest take away is that I should have done this a long time ago!"

Very nice battery, good customer service, but poor integration

"I recently purchased the Eco Battery thru hole LIFEPO4 battery upgrade kit for my 2021 Advanced EV cart. The battery and packaging were very well done, the Extreme Kartz (EK) support was good, but the integration of the kit leaves a bit to be desired. I watched all the installation videos and did hours of research before purchasing. On initial install, the battery cables were too short and I had to rotate the battery 90* to make connections. This put the battery connections too close to the charger and makes the on/off button difficult to access. I was told when ordering that a SoC meter would be included…sadly a meter was not included and is evidently not a part of the kit. EK support told me I could use a Tech Tool and reprogram my controller to use my existing gauge, which is not true according to EB tech support. The only way to get SoC is by using the EB app or purchasing a meter. TLDR: to make this kit work you will need to spend $70 on new battery cables, $80 on a new meter and $90 to rent a tech tool that may/may not work."

Complete bundle, easy install

"I have a 2019 advanced ev i40l. I ordered the thru hole 48v/105amh battery bundle. After watching install videos, the installation was straight forward and easy. I've had a 2mph increase overall, up and down hills. Battery life is great and remote wake-up button is nice as well. Other friends are looking to upgrade their carts as well after seeing install on my cart. Great customer support from Extreme kartz. Glad I chose them as my supplier."
