48V 105Ah Golf Cart Lithium Battery, Built-in Smart 200A BMS with Touch Monitor and 20-Amp Charger, APP Supported, MAX 10.24 kW, 4000+ Cycles Charging, Designed for Golf Cart

I put this Mosasaur 48v battery system into our 2014 ezgo golf cart.Overall, we are very happy and impressed with it. The cart speed is up. I can't tell you what the speed difference is exactly, as it doesn't have a speedometer, but you can tell by the sound of the tires. The pitch is higher which means you're going faster.The other thing I noticed is the amount of torque. You could always tell when you were going uphill, you could hear it and feel it slow down. With this system, it doesn't slow down, it'll actually maintains speed because of the torque increase.Another awesome thing is the weight reduction. The cart originally came with 4 Trojan batteries that weighed almost 80lbs a piece. This complete system is roughly 120lbs. I say complete because I mounted the charger on board, plus the monitor and voltage reducer. So about a 200lb reduction.In the pics I hope you can see what I did to mount everything and why.The charge outlet was smaller than what was originally there. I used to pieces of wood, one outside and one inside. Screwed them together to capture the existing opening and clamping it in place.The battery itself is mounted more to the driver side because of all the connectors will have to go on the passenger side. I tried to use the old battery hold downs, but it still could be moved side to side. I ended up using through bolts and using an extra long drill bit. I just punched 4 holes to fit. It has zero movement now.The controller is also on the passenger side leaving very little space, so moving it over takes care of that. I was going to mount it first, but do all your hookups to see exactly where it needs to be before you mount it.You'll also see that where the fourth battery used to be there is now room to mount the charger onboard. It has a carrying handle on it that I tied the extra wiring to. Not the nicest job, but everything is secured in place.If you're a diy person, this is an easy but challenging project that is very well worth it. If you're not handy, either higher someone, or find a real good friend.I've already had a couple friends look at the set up and are going to ordering it for their carts as well. I would definitely recommend it to anyone that will be needing to change their batteries.Our batteries were at that point of replacement. We looked at the cost of the same batteries, staggering to say the least. We chose the Mosasaur because it suited our cart, there's virtually no maintenance, and the price was very little difference. So the fact that it is more powerful, lighter, and no maintenance or mess, it's very well worth the extra $150 or so in upfront cost.They have different battery configurations that will fit many other applications.The company also makes it worth it. Most systems come from overseas (China). Mosasaur has a warehouse in California. Our order said expected delivery was over 2 weeks. We got it within 5 days. I also got quick response on a question I had.Hope this helps...

There wasn't really any problem with the battery. It came with everything it was supposed to. The installation was easy after we got old batteries out. The power was impressive. Guage worked well. The charger worked fast too. Can't say enough good stuff about the battery. I would definitely recommend it to my friends and family.

Sofa King LOVE my Moasaur Lithium-Ion battery!!!I have a 2021 Bintelli Beyond golf cart (me gusta mucho as well!) that I replaced my 6 x 8 volt lead acid batteries and it is amazing. Battery fit well and was really easy to install and setup.I can run my amp, subwoofer, and phone all day long. And I can definitely feel the weight reduction (was about 360lbs before). The governor is topping out at 25mph on the hills.It literally came with everything we needed to drop it in. We were up and running withing 2 hours.It's amazing how much louder I am while crusing the links.

So far.... VERY GOOD!! Everything arrived intact with no damage or missing parts. I did not use the bolts that came with the kit to install the battery and charger since I needed to build a shelf on the battery frame to hold everything. The Mosasaur battery does not fit in the frame as bought. They have a narrow version and that might work without building a shelf but I don't know. It was easy to build with some pressure treated 2x4s for weather protection and a piece of plywood for the shelf. I then held the battery and charger in place with self tapping screws into the wood.There are no instructions for particular models of golf carts (not their problem) so you have to make sure you are wiring everything per the particular brand of golf cart. In the case of EZGO, that meant making sure you reconnect the grey wire to the positive lug or the cart won't go anywhere.I charged the battery to full 100%, finished the install and took it out for a ride. No significant rise in speed, I expected that. But it definitely accelerated quicker. After a 10 minute ride, pushing top speed and acceleration for the test, I had only burned 4% of battery power. At this rate I will only have to charge the battery once a month or 6 weeks. Saves on my electric bill also since the lead acid batteries were always "plugged in".All in all I am impressed so far with the battery system.

I am not a professional and found the battery. Relatively easy to install. It has worked perfectly for several months now.

This is a huge improvement over lead acid batteries. Our cart is 212 pounds lighter and much quicker. Charging is quick and easy and maintenance is minimal.

I would not buy a battery from this company. I bought a battery and it was defected and I can’t get a hold of anyone to get a warranty replacement.

Comes well packaged and appears to be very good quality. The floor of my golf cart is not flat so I found it easier to mount a plywood floor in it that the battery can securely mount to.The original RXV charger port has an interlock. If you want to eliminate it, you must run a pigtail from the blue wire to the positive side of the battery or you golf cart will not run. (See the bottom left corner of my picture). My cart has more Torq and more speed now. Very happy with the value of this upgrade.
