If you have lead acid batteries, you should get this ASAP. Unbelievable difference.
Wow. Seriously. Unbelievable difference in both performance and speed. Simple installation (the only thing not discussed is the reed safety on the old charger plug. You need to cut it before the fuse, put a ring connector on it and connect it to the positive terminal). The display works, but is wonky to turn off. If you download the Bluetooth app for your phone, you don’t need it anyway.After installation, I thought about registering the cart with NASCAR. Huge boost in speed, but more importantly power. Absolutely no lag or drag…. I think it would kill Pike’s Peak. Seriously will never go back to lead acid batteries. This was cheaper than replacing all 6 old batteries, and the difference is night and day. Highly, highly recommend.

Lithium vs 8 Volt golf cart batteriea
Best Purchase ever! replacement of 6 8volt golf cart batteries to 1 Lithium battery -less expensive, more convenient to fit into a golf cart and lasts longer on a charge. There is less maintenance on the new battery and easy connection.Everything is working great, have no complaints, delivery was perfect as well!! Easy life!!

Excellent Lithium Battery Choice for Replacing Bank of Batteries in Golf Cart
This is a very good battery. It was an excellent swap from the standard bank of batteries on golf carts. It was very easy to install. There are several places that you can get installation instructions to make the job easier. It has improved my battery life and reduced overall cart weight. It is also faster to charge. It fits in well and snuggly into the battery compartment with the supplied straps.

Very Easy installation – Yamaha Drive 2
Replaced a set of Trojan batteries in a Yamaha Drive 2. We could get one drive around the neighborhood and they would die.Packaging was perfect. All parts needed were included in the kit except for some wood screws for this specific installation method, see below.There was a noticeable increase in acceleration but not any increase in speed. After spending twice as much time as we could get out of driving with the old batteries, there was still 83% left on this beast.I like the fact that this battery has an on off switch to keep any drain on the battery from happening when not in use.The gauge works well. One thing I noticed is that if you keep the battery switch on you can switch the battery off from the gauge on screen 2. I heard the relay that controls the power switch kick on and off when the screen button was pressed. Lots of good information on the gauge. It reminds me of the gas mileage calculator in my vehicle. It shows you how much time you have left on the battery based on the current consumption. For instance it shows a massive drain when you are accelerating but drops back significantly when you are up to speed. The only thing that I found that could have been better is the hole that the screen mounts to could have been slightly smaller to hold the screen tighter but after mounting the bracket to the cart it seemed to hold ok. BTW the cord that comes with the monitor screen is super long. See how much is rolled up in the pics.I chose to install the charger in the cart just make the indicator that it is charging viewable. I think you need to turn the battery on the first time you charge it.Overall I am very pleased with this installation. I liked that this battery case has the flange on the bottom to mount the battery in the cart instead of a strap.As far as how long it lasts, we will see. Yes there are cheaper batteries out there, I chose this one based on the other reviews and the way the case was made.A tip on the Yamaha Drive 2 installation. Get a Multitool with any flat blade and a small piece of 1×4, lay the piece of wood down next to the plastic ribs at the bottom of the battery tray and cut the rib down to 3/4 inch. This allows you to use a piece of 3/4 plywood as the base and have a nice even surface to set the battery and charger on to while maintaining some strength in the battery tray.

Yamaha G29 Lithium Battery Upgrade – Wow!
Just received my Elefast 48V Lithium Battery on the promised date. Everything was packaged really well, and the instructions were easy to follow. My husband installed it in our Yamaha G29 golf cart modifying the original battery mounting brackets using a multi tool. The 18-amp charger quickly charged the new battery to 100% in no time. The first drive was incredible, we can’t believe how much more power and additional speed the cart has now. This is great value for a complete package that includes everything needed to convert your golf cart from old acid batteries to lithium. I would highly recommend this battery to anyone needing to replace or upgrade their golf cart batteries.

Game Changer!
This is a game changer. Easy to install, works great, less maintenance and cheaper than wet batteries. This has a longer warranty than a wet battery and charges faster. My 1997 Club Car has more speed, plug and play. The Bluetooth isn’t a needed thing.
