CHINS 48V Lithium Golf Cart Battery, 48 Volt 100Ah LiFePO4 Battery, Built-in Bluetooth 200A BMS, Includes 48V 18A Charger, Monitor, Perfect for Golf Carts

Choose this as it was the cheapest 48v 100 ah battery I could find. Came with the charger that takes about 6 hours to charge. Was easy to install and just works right after install. The app connects with Bluetooth easily and stays connected. There is a good amount of data in the app. Really only look at battery percentage. Did not installed the shunt volt meter as the app works well. Been through a few cycles over the last month with no issues. Handle make it easy to lift with 2 people and doable with one person. Getting between 30 and 40 miles in my club car.

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.

Case appears built well. Handles make moving it easy....it is heavy. Replaced 8 lead acid batteries in Club Car DS extended cart. So, saved almost 500 lbs. Got almost 20 miles out of it and still had over 50% charge, pleased with that. App and bluetooth connection work well. Wish there was some other way to turn battery off and on besides the app. If the app or BMS in the battery fails, then battery will be worthless.Charger works well, charge speed is a couple hours from 60% to full I think, didn't time it. I wish charger/charger fan would cut off when fully charged.Weakest link in the system Chins provides with this battery is the monitor. It's unnecessarily complicated. Just watch the video on how to program it. Multiple steps, and nowhere does it explain all the functions or how to set them. You just fumble through it until you figure it out The wires attached to the monitor are very thin. Yes, they're low voltage, but easily broken as you splice them and run them through your cart. I almost threw the monitor out and just bought a separate SOC monitor that looks better than this Chins monitor. But, I made a bracket and mounted the Chins one for now.Used 2 ga battery cables as I run them almost 6'. Overkill, but less voltage loss.Bought a 48v to 12v converter for cart accessories/lights.Bought a battery hold down kit to mount battery. Cut a piece of extra starboard I had, bolted it in cart, put a thin piece of foam under battery for cushion, and mounted battery on board.Still cleaning up the wires. I'll run a plug for the charger through the fiberglass body at some point.Love the performance. Much more torque, but losing almost 500 lbs of weight is part of that.Had it a month, and happy with it so far. Hopefully the same in a couple years.Shipping box was busted open. We were lucky that the charger and monitor didn't fall out of the big hole in the box. Could be packed better.
