We had one battery starting to go out on our golf cart and another one with a broken post so we just decided to fully change out the lead acid batteries for lithium. The install was very easy. 6 8volt batteries out 1 48 volt battery in. Literally just hooked up the starting positive and ending negative to the battery pack and everything worked right away. Before our golf cart went about 22-23mph on a flat surface and now we can sustain 25 mph easily and have hit 27.5 mph. Most of the improvement though has been in the responsiveness and initial start. This battery lets us get to 20mph way faster than the lead acid batteries a could. Not to mention the fact that this battery weighs so much less. So far it seems like we can get about 30 miles of range from a full change. The batteries charge very quickly and I appreciate that all it needs is 10 amps over 15 like our old charger. The app is very basic but very functional. Reviews on the App Store are low but I have no idea why. It always connects right away. I was honestly blown away how fast everything connected in the app. Easy to pull up and check the batteries after getting back from riding around. All in all this is a must do easy DIY upgrade if you’re a golf cart owner. Great value for what you get, and great power output. Honestly blown away.

10 week update - this battery has been great and zero issues with it. It’s been strong hills and am seeing 25 mph on level ground with the speed magnet. My brother in law has 4 year old lead batteries and has been keeping his cart plugged in all the time and I’ve been comfortable letting my cart sit when not using it. I don’t understand why anyone would still be buying flooded batteries but they are. It’s been a month and I’m super happy with this 48v battery and 10ah charger. I get about 1 mile per 2-2.5 percent of battery. Charges at a solid 10 amps per hour as expected. I ended up putting a speed magnet on my motor sensor and my speed went from 18 mph on 27’s to a solid 24 (up to 28) - this tricks the battery to think your going slower but anyway, the reason why i say this is because the battery delivers more power than flooded will. I also used to have to get a running start to load my cart on my truck and now I can almost crawl up if I want to (I haven’t tested this totally but I loaded my cart last week from a dead stop on the ramps and it moved right up them). So almost twice the range, no maintenance, ease of charge, about 270 lbs lighter, and longer life. I did some trimming in my compartment to center the battery in my precedent. I also installed buses for the power so everything isn’t wired on the battery and installed a ac power port for charging. There is only one negative and that is you can’t mount 2 in your cart. Don’t even think you can. This takes up more than half of the width of the battery compartment. But you still getting upto 40 miles on a charge. One more thing. The bus application works well. You can see all the internal cells, check temperature, charge, load, etc. you can also turn off discharge (I’m doing this now because I’m leaving my cart for 2 weeks and figure it’s safer that way. All you have to do to run the app is download it and open it up near your battery and it will connect via Bluetooth automatically. No need to pair or connect via the Bluetooth settings. It’s probably best to reopen the app when you want to connect to it. Sometimes it’s tricky to connect if you walk away out of range and come back in range.

The battery was very well packaged and arrived 2 days earlier than promised - 5 Stars. The battery does as promised Our golf cart now runs extremely well with an extended range. - 5 Stars. The battery charger was easy to mount and charges the battery quickly - 5 Stars. The bluetooth battery App was slow to "hook up" the first time but has been instantaneous since and gives you all the information you need at a glance and is easy to use - 5 Stars. The battery monitor module took a fair bit of work to hook up and then turned out be essentially useless. The problem is that it correctly monitors the amp-hours used but when running the cart but then when you put the battery on charge, instead of counting down to zero as you replace the amp-hours already burned, it continues to count up. You could re-zero the amp-hours after each charge but this is not a trivial task. Do not bother to install this meter. - 0.5 Stars Had the package not included the battery monitor at all, I probably would have given it 5 Stars.

Update: still running strong after 50 charge cycles so far!! Came packaged very nicely. Charger is in individual box inside the whole box. Came a little banged up but I imagine it’s from shipping. Connecting this (see picture for test run) was insanely easy. Be sure to use a Reducer for all the lights etc. doesn’t come with one (you can find them pretty cheap on here). I saved just over 300 pounds swapping from Interstate Lead Acids. Charging seems decent. It’s 10amps. It takes about 1 hour for roughly 10%. I am running 18” wheels, 4 gauge wiring, and a Navitas 440. Stock I was lucky to hit 12 mph, after the controller I could hit 20 mph. After the battery upgrade I’m hitting 24/25 consistently and I imagine it’ll bump up a few after the battery “learns” my driving habits. The distance compared to the lead acids is insane. I would be lucky to hit 10 miles before the draw was too much for the batteries. I’ve ridden every night (have had 5 days) over 25 miles and still haven’t really pushed it. The lowest I have gotten is 43%. The battery arrived as well with over 50% charge. You can name it through the app. Super easy to connect and monitor and even has a “battery balancer” mode and you can see in real time the temp of the battery and the BMS. I’ve had no issues with either. Super happy with this product and will be updating in time (1 month, 6 month etc).

This battery is awesome its lightweight my cart is faster i get twice as much run time in between charges easy install and the bluetoth app is a great tool cant go wrong with this setup
