OGRPHY - 48 V 100 Ah LiFePO4 Bluetooth Battery 5.12 kWh Grade A Lithium Battery with 500 A Peak Current, 5000 + 48 V Lithium Battery with Charger for Car Applications

Installed this on a 48v EZGO TXT. Battery tray needed some modification/ cutting with an angle grinder to allow the new battery to fit. Not difficult, but it'd be nice if the battery fit the application as a drop-in. Wiring was easy, though it's not a true plug and play with the TXT. Some adaptation was required, but it's relatively approachable for a DIY handy person. LED screen looks great, with helpful information. Performance is as expected. Much stronger torque, higher speeds, longer battery life. Very happy with this kit!

Wasn't an exact fit since the cart was originally a lead acid cart, but a quick move of the center control board on the Club Car and it fit easily on the passenger side. Connections are easy since I did the lithium conversion years ago. Did a LOT of research after going through 2 lithium batteries in the last few years. Both batteries failed because of cheap cells, definitely not grade A cells. The components on these are much better, the included charger and battery display unit are also much better. The bluetooth phone app is nice, tells you the condition of each cell and displays everything you need to know about battery health. I'm hoping this battery lives up to it's life expectancy, early indications indicate that it will. Plenty of power and it definitely lasts a long time in between charges.

The biggest job by far was removing the old batteries. The installation was smooth as silk. The power and weight reduction combined to greatly improve performance. Of course it's too early to know about durability and life. The person who helped me with the job had recently installed a much more expensive conversion kit and he said this one was a much more complete kit and he wished he had purchased this one.

Battery was easy to install. Bluetooth app is quite easy to use and has all the data neeed to monitor state of charge. On-board charger is working well. Did not alter oem charging receptical, just use an extension cord to charger under seat. Good value for a quality product. Cheaper than lead acid replacement batteries.

The battery quality and company communication to date is excellent. However, monitor/shunt installation (and included very short wires) are ill-conceived and instructions to set up the monitor are absolutely horrible. Someone that speaks and communicates good English should have written (or at least proofread) the instructions for setting the monitor up. The wires are ridiculously too short unless you want it under the seat where it cannot be in view as it should be. UPDATE: After using this battery for over a month, I'm less than impressed with how long it lasts. We went out of town for 3 weeks. When we left, the battery was 77% charged and NOTHING was left on (verified by the bluetooth, so there was no parasitic drain). When we returned, the battery was at 28%. I have noticed that the battery does not last nearly as long as most reviews claim. I have been monitoring it via bluetooth, and 2 or 3 cells always seem to have a lower charge than the rest (gray color on the bluetooth). Even after fully charging, these cells stay gray - not green or blue. NOT HAPPY!! UPDATE: So the Seller offered to replace my defective battery and the replacement is working better. I really do appreciate the customer service and desire of the seller to make this right. UPDATE: Battery charged and ran the golf cart for a pretty long time between charges, but now the battery shows 0% charge. It was at 26% about 2 weeks ago when I checked it on my phone, but ran down to zero without being used! (nothing was on!). Now, plugging the charger into it, the battery is failing to charge. Tried reaching out to customer service, but Amazon's system will not let me.
