Bedrock Battery 48V 105Ah Compact Lithium Conversion Kit

Bedrock lithium battery conversion kit…

Bedrock lithium battery conversion kit contained everything required for my Yamaha Drive 2 golf cart. It was perfect, even the battery gauge fit perfectly replacing the stick Yamaha gauge. Only had to drive 4 holes to mount the battery brackets. Instructions were easy to understand.

My experience with bedrock was amazing

My experience with bedrock was amazing! Not only was the install far easier than I expected, especially for someone with limited mechanical knowledge, but the support that they provided throughout was amazing. I had one part that needed to be replaced and they immediately sent a replacement overnight. They also took the time on the phone to go over all of my work to make sure that everything was done correctly, even though they didn't need to. They really went above and beyond, and I would highly recommend not only the product but their support services as well. My cart is working better than it ever did with more power than ever thanks to the new battery upgrade. I couldn't be happier.

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.

trust my research, or perform your own

Did extensive research and ended up at Bedrock. Didn't need extra fluff with a heater, I live in the South, but wanted a MILSPEC best warranty in the bus, w/ focus on cell tech/performance. The look, the packaging, their customer service, their instructions were all ozzing w/ easily understandable detail with elements of humor, everything's solid. Replaced a 6 stack lead with a 150 amp Lithium. Didn't need the bracket they provided, they furnish everything you need including bits to configure your tray as you want it. Took me a day to execute.. One caveat, I called them today just to provide some verbal accolades and a few questions on the warranty registration; one of their US based electrical engineers answered their general line and took care of my registration and availed himself to field other banter. Found it impressive that an engineer answered a ringing general inquiry line... thanks Matt, well done..

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.

Excellent kit and instructions

Excellent kit and instructions. The 65ah battery is perfect for our 48v 2016 club car precedent. Ours is not modified and only used around the neighborhood so the range is more than enough. Very DIY friendly, just plan ahead with bolting the battery down. Underside of the cart is honeycomb and you will want to be able to find your bolts.

Easy to install 48V Bedrock Lithium Battery

Ryan at Extreme Kartz was very helpful in picking the right lithium battery for my EZGO Freedom RXV golf cart. The 48V Bedrock battery was simple to install after watching the step by step installation video. I liked the price point of the Bedrock battery and the 10 year warranty coverage. I installed the SOC meter next to the charging port instead of the dash board to simplify the install. Looks great with a lot less work. Very happy so far.

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!!

Ezgo 48v lithium conversion

Converting my Ezgo from lead acid to the Bedrock lithium battery was a very doable DIY project with the available instructional videos they have posted. They cover every aspect of converting your cart to lithium. When I did have a question they provided great customer service responding promptly back to me. I definitely give them 5 stars on the quality and the whole experience. My cart runs so much better now.

A great investment!

being a new golf cart owner I'd called bedrock with a few questions to make sure they offered something that was just right for me. Ryan did a great job of explaining their products and help me choose the battery that fit my family and our golf cart. Installation was easy and I couldn't be happier going up hills with all the power!

My order arrived quickly and packed very well. I've finished the installation and the difference in my cart is amazing. Lighter, faster, stronger, and cleaner. No more battery corrosion! I only wish I had done this sooner!

Great install

Great install! I appreciated the extra parts in the kit. Customer service was excellent—they confirmed the correct battery for my needs and explained their reasoning. Setup was even easier than expected since the 12V converter and extra wiring weren't required.

The ExtremeKart team was extremely knowledgeable,patient, and honest.

The ExtremeKart team was extremely quick with responding to my questions and concerns with everything answered. They followed up with me in a timely manner. They corrected a shipping mistake made on my end. The shipping process was fast and detailed. The packaging was the best I've seen. Everything was in separate boxes contained in one big box, all components were wrapped with foam. The instructions were detailed and in color. The battery was very impressive, being shipped in its own little crate. Everything was so well put together and the instructor is out so well that I never had to call back with questions. My install is complete now and im going to send videos of the unboxing and installation. Thank you to Bedrock and Ryan from Extremekarts!!

48V 105ah Battery Kit - 2019 Club Car Tempo

I purchased the 48V 105ah lithium battery kit for my 2019 Club Car Tempo after talking to their team on the phone. They answered all my questions and were helpful in the decision making process. I installed the kit myself and have golfed over 10 rounds with the battery so far. It goes from 100% to around 80% after 18 holes of golf which is way better than the previous lithium batteries I had from china. I'm super pleased with this product and think it's a great bang for your buck!

Easy conversion from lead-acid batteries to Bedrock's lithium battery

We ordered a 51V 65ah for our 2004 Club Car Precedent that had the 48V lead acid batteries. We watch the videos provided by Bedrock Battery on their YouTube channel. It was a simple and easy conversion. Our golf cart is back to functioning. I love the battery gauge to know when to plug it in for a charge.

Bedrock 65Ah lithium battery

I recently purchased a Bedrock 65Ah lithium battery for my 2019 Club Car Tempo from Extreme Kartz and couldn't be happier. Before buying, I spent some time looking through the Bedrock website; the quality of their knowledge articles and installation tips is fantastic, which really helped me feel confident in making my decision. The Extreme Kartz sales team was excellent to work with, and the included installation instructions made the swap on the Tempo clear and straightforward. I also reached out to online support, and they were super helpful. Great product backed by amazing resources!

Bedrock 48v lithium battery conversion. Compact.

The videos were great just need more detail on booking up battery and hooking up accessories to the converter. Customer service was fantastic in getting what I needed for my EXGO RXV 48v. It was hard work in the garage but she runs like a dream and is very fast.
