CHINS 36V Lithium Golf Cart Battery, 36 Volt 100Ah LiFePO4 Battery, Built-in Bluetooth 200A BMS, Includes 36V 25A Charger, Monitor, Perfect for Golf Carts

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.

Received 48volt battery in good condition. Was skeptical at first after watching video of how to use the battery monitor. I wasn’t sure if I had to do any programming on the battery before installing. Luckily I didn’t. But unless you plan on cutting a hole out to mount the battery monitor. It’s kinda useless. You can use the app on your phone to monitor battery. It was pretty easy. Just follow some simple directions then plug and play. Of course I had to do some modifications on my battery box so I could fit the one battery where the six old batteries fit. Just FYI I have a Yamaha G29 electric golf cart I also had to secure the battery from sliding around and bouncing since I use this cart as a farm cart. I have had the battery about a week now and everything is working fine. The cart seems to have more power than before and goes uphill a lot better than before. So far very pleased.
