Extreme team were very knowledgeable about their battery and associated kit accessory products and were able to clear up questions I had related to confirming the correct items to order based on my cart’s configuration and controller. The shipping was fast and kept me up to date on the two shipments, including the tool rental refund on the deposit.

I have now installed 4 conversion kits and have zero issues. The staff has been incredible and go about and beyond. I was having an issue after installing one and the staff was very helpful and i was able to trace the issue down to the Modular.

I ordered a Bolt 48v lithium battery from Extreme Kartz after many hours of reading through their Lithium battery comparisons which were a huge help and ultimately the reason I ordered through them, because it goes above and beyond what other online retailers are doing and the lithium battery rabbit hole can be a big one to fall into. Shipping was quick, communication was great and the product arrived just as advertised. I will definitely use Extreme Kartz again!!

Excellent products. Just finished upgrading my Club Car batteries to the Bedrock 105AH Lithium Battery. The products came packaged very neat and organized. The battery was shipped in a very nice wooden crate. Installation directions were spot on. Looking forward to some summer cruising.
