Bedrock Battery 48V 105Ah Slim Upgrade Kit
"Well designed product with straight forward installation instructions. Yamaha G22 has never run better. Little things like providing a battery strap to help remove old lead acid batteries was very nice. Communication with the retailer Extreme Kartz was excellent."

Bedrock Makes it Simple
"The Bedrock Lithium conversion was so simple, I couldn't believe it. And the 48v 105 AH slim battery is awesome. Increased my level-ground top speed from 22 to 27 mph, and the power going up hills is night and day. I can actually get the two front wheels off the ground if I am in a steep enough area. Getting to the course, doing a full round, and then back home uses about 25% of the battery, and I have a four person raised cart with large wheels. That kind of range is off the charts."

Had a great experience with Extreme
"Had a great experience with Extreme kartz and Bedrock batteries. The team at Extreme was very helpful. Ryan answered all of my questions and helped walk me through the buying process. Shipping was extremely fast. Install was easy. I purchased the 48v 105ah slim package and it seems to be a great package. The quality of the battery system appears to be very durable. This system is on par with the quality of batteries add a much higher price point. I would highly recommend Extreme Kartz and Bedrock Batteries. Install was on a 1991 EZGO Marathon."

Really easy process in selecting the…
"Really easy process in selecting the battery for our icon i40 lifted golf cart. The bedrock battery came with everything I needed and even included some extra items which made the process even easier. The instructions were easy to follow and was able to find quick solutions to any issues that I was having with the install. The performance from switching to a lithium battery is awesome, wished I would have done this sooner. Completely satisfied with our Bedrock battery and support and shipping from extreme kartz. Thanks!!"

So far pleased
"For two seniors installing with some help with our grandson it went pretty good. The instructions could be a little more detailed for a novice. But, once we established email communication with Matt, everything went great. Matt was very helpful with our questions and concerns, as well as responding quickly. Extreme Kartz was great."

Bedrock Battery - EZGO TXT
"The Bedrock Battery 48V 105Ah Slim Golf Cart Lithium Conversion Kit delivers exactly the kind of experience you hope for when upgrading—simple, smooth, and hassle-free from start to finish. Installation was refreshingly easy. The buying experience was just as smooth. The transaction was straightforward with no surprises, and communication felt professional throughout. Shipping was quick, and the battery arrived well-packaged and ready to go, which adds confidence right out of the box. Overall, this is a great choice if you’re looking for a lithium upgrade that doesn’t turn into a project."

The comfort of having everything needed
"The comfort of having everything needed for the install and knowing a Bedrock employee is a phone call away to help with any questions. All items were delivered on time, and the installation video was step by step and on point. I am not a mechanically inclined person but I followed the video and had no problem installing my Bedrock lithium kit on my 2019 EZ GO TXT."

No Regrets! Top tier Conversion Kit
"I have been on the hunt for a lithium battery conversion kit for my 2023 Icon Golf Cart for months. The Lead acid batteries were toast and the joy of a golf cart was annoying at this point. After watching many videos on Youtube I came across Extreme Kartz and after one phone call speaking with their Tech named Matt I was ready to make my decision. He actually recommended Bedrock for my particular application and price point along with Service and parts made here in the USA. As soon as I ended the phone call I purchased the Bedrock 48v 105ah slim conversion kit. I over thought the process from start to finish on the install but I am absolutely blown away at how simple the install actually was. Absolutely love the new Lithium Battery and everything it offers that I just was not getting out of the lead acid batteries. Thanks Bedrock Battery for offering a superior Battery and conversion kit, and especially thank you to Matt at Extreme Kartz for pointing me in the right direction"
