Received text pretty quickly after order letting me know my battery was about to ship and please reach out if I had any questions. Battery arrived quickly well packaged with all accessories. Directions were clear and easy to follow with installation being fairly simple. Very happy with the communication, shipping speed and level of support offered.

This item takes the ease of installing the bedrock battery to a new level. No drilling is needed with its precise design. Very strong support where its needed. .

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.

Very happy with our new purchase and it was an easy install. Golf cart works great now and lucky to have found such a great product at a reasonable price.

Bedrock Battery kit came with everything you need for a lithium conversion. The install was pretty easy and straightforward. I strongly advise to watch the installation video on the website for a good overview.

I got the slim battery for my Star Sirius EV. Night and day after replacing our lead acid batteries. The battery fit perfect and bolted right to the frame. Also works great with our 440A Navitas controller!

Well packaged for shipment and arrived with no damage. Install was simple and instructions were complete. Cart runs great and range appears to be more than adequate. Folks at Extreme Kartz were available and helpful before and after the sale.

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 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!!

Great battery. Easy install

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.

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.

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

All the support from the Extrem Kartz staff in the selection process, and the completeness of the installation materials from Bedrock made the conversion less intimidating. The fit and finish of the product and packaging were top-notch.

And the bit of humor was appreciated.

Highly recommend this option for lithium conversion.

Happy with this battery and ease of installation!

This battery has more power, torque and a longer battery life than my previous lead acid battery's. The conversion was easy with there step by step guide and detailed information about my ergo golf cart in the guide and online videos. If you're in the market for a lithium upgrade I highly recommend this battery!! Easily does 22mph! With lift and tires!

These guys are best in class with service and response. Love their 10 year warranty on my battery and the fact that they are local and I won’t need to worry about ever having to ship a bad battery down the road back to China! They’ll take care of me.

We have a TXT with a Navitas controller, and the Bedrock Slim was perfect for it. Got much more power than we were expecting, honestly. The Bedrock crew was outstanding. Went out of their way to help me out. Would definitely recommend.

I'll start by saying total time to install was probably 4 hours that I stretched over 2 days. I installed this in a 2017 EZGO TXT, that was rebuilt by a local company. Getting the old batteries out and cleaning everything up while figuring out what wires went to what took more time than anything else. The install was simple and straight forward. I used the upgraded main power wires too, hopefully you can tell by the before picture it was time, lots of corrosion. My only suggestion, not a complaint, replace the self tapping screws with bolts. I did this on mine because I like the security of a locking nut over the potential of a self tapper working its way out for the charger and 12v converter. The only other thing is that I had to add a 2" gauge bracket for the round battery gauge due to lack of dash space, an option at the time of purchase would have been nice. The install video was spot on and easy to follow. I only had lights to install on the 12v side and I made sure I needed the converter before I purchased. After I realized that the lights attached to one battery in the old system is not the same as being attached to one 48v lithium, using the included splice connector was helpful. The only thing I had to use not in the box was a couple of random bolts instead of the self tapping screws, my choice, and some zip ties to secure the cables running from the battery compartment to the gauge and key switch.
