LOSSIGY 48V Lithium Golf Cart Battery with 18A Lithium Charger and Monitor, 48 Volt Battery Conversion Kit, Built in 200A Bluetooth, Peak Current 1000A(3-5s), Prefect for RV, Solar System

I recently installed the LOSSIGY 48V 150Ah Lithium Golf Cart Battery in my Icon i60L, along with the included display and 18A LiFePO4 charger. The entire project took about 2.5 hours with help from my two sons. That included removing the old AGM batteries, cutting and painting a treated plywood board, and installing the new battery, charger, and existing 48V to 12V converter. Installation Notes • Battery fit perfectly in the Icon i60L with no clearance issues. • We positioned the battery so that we could use the existing battery cables. • We replaced the original battery tray with treated plywood mounted to the metal frame beneath the tray for a clean, secure, and easy to work with surface. • Be cautious when drilling as there are suspension parts and brake lines underneath. Measure carefully before committing. • Modified the existing charger connector to accept a standard female receptacle for easy plug-in. NIGHT and DAY Performance Upgrade This battery transformed my Icon i60L from sluggish to sporty. Before the upgrade, the cart ran on 8x 6V AGM batteries. Fully charged, it would get up to 27 MPH downhill and struggle to reach 18 MPH uphill with a full load. Acceleration was quick for the first couple of minutes and then would get extremely sluggish , and uphill climbs felt like a slow grind (faster to walk). To make matters worse, the AGM batteries only lasted a little over two years, even with light use. Now it’s a whole different machine. • With the LOSSIGY lithium battery, the cart rockets to 30+ MPH downhill and powers up to 25+ MPH uphill in seconds. The torque and responsiveness are instantly noticeable. • No more waiting for the cart to “wake up” on inclines. Acceleration is smooth and immediate. • The nearly 400-pound weight reduction from removing the AGM batteries makes the cart feel lighter, more agile, and far more enjoyable to drive. • Whether cruising flat roads or tackling hills with passengers, the cart maintains consistent speed and power without hesitation. This upgrade didn’t just improve performance, it redefined how the cart handles. It’s faster, stronger, and far more efficient. If you’re looking for a serious performance boost, this battery delivers. Display & Monitoring: • Display works well but isn’t weatherproof. I plan to 3D print a case to mount it safely under the battery compartment. • The Bluetooth app is excellent—shows real-time power consumption, battery health, charge cycles, and remaining battery life. • Much more reliable than the Icon dash, which tends to show 100% even when the app reports 90%. Charging Experience: • Battery arrived at ~50% charge and took about 4 hours to reach full using the included 18A charger. • Charger is loud and gets warm, but that’s expected and doesn’t affect performance. • Love the battery switch—safe wiring with no sparks. Battery automatically powers on when connected to the charger. I was originally planning to replace my AGM batteries with new lead acid ones, but this lithium upgrade was more affordable, more powerful, and far superior in every way. If you’re considering an upgrade—go with LiFePO4. LOSSIGY delivers a fantastic product that’s well worth the investment.

I’m running this on a 2010 club car. Install was easy, had to build a small frame to sit it on. Charging is quick and seems to last 2-3 days with regular use. The cart seems to have an increase in power compared to the standard batteries. Takeoff is a lot quicker. Update. After a little less than a year of regular use. The battery stopped charging, then stopped outputting any power. I contacted Lossigy through Amazon. After a couple days of troubleshooting and sending them photos, they agreed the issue was a failed internal temp sensor. They honored the warranty and shipped me a replacement. It is now installed and working great.

Easy to install. Much lighter than 6 lead acid batteries, I was able to install by myself very easily. Hold a charge longer. Recharges quicker. Costs the same as six 8 volt lead acid batteries. What else can I say. I have been using this battery in my golf cart for the past 6 months and am very pleased with how much capacity this battery has. Normally I have to charge my cart every night on the weekends to keep up. This one I normally charge it when I put it away on Sunday and it's ready the next morning for the week. I did have the charger fail after 6 months causing the battery to go into protect mode. With a message to Lossigy and some troubleshooting with them it was replaced at no cost. Very friendly service and help me troubleshoot to find out what was wrong easily. I Would definitely recommend this to anyone looking to replace their golf cart batteries. Can't say if it will last 10 years, but if it does that's twice as long as the lead acid batteries I have been using, I did the best name brand in lead acid golf cart batteries and replaced them every 4-5 years. With the reduced number of charges needed I can see it lasting a long time. I have also noticed that unlike the lead acid batteries, the run rate is consistent from the initial charge to the point of needing to be charged, like the BMS is always outputting the same voltage across the charge. I like this, but it does cause the speed to be a little less at the beginning of the charge vs being fast at first and slowing down as the battery is drained.

This Battery is the Absolute best value for the money today! I have just replaced 2 sets of lead acid golf cart batteries in the past week. One for mine and one for my neighbor. Both EZGO RXV's. The battery functions very well and can be monitored using the app on my phone. I have driven both carts while monitoring the batteries and after 18 holes of golf and trip back and forth from the course they still register over 80%. My friends cart is set at high speed and does over 30 mph mine is typical with a max of 23. You will need to have your own strap to tie the battery into the tray and will need some self drillers to mount the charger in the compartment. I did not use the shunt and meter that comes with the battery because both carts have a meter that works fine and have the app on my phone with much more battery information. There are no instructions that come with this Battery, so you'll have to know what needs to be eliminated (3 wires from the old charging port) and changed (1 Blue wire from the charging port has to go to positive Battery Terminal). I am also going to add a new charging port where the old one is.

Battery is great! Gave new life to my 2012 E-Z Go golf cart. I purchased this battery because of the great reviews. Installation was actually pretty easy. Did make a mistake initially and couldn’t get it to work. Tried to contact company through their website and email but never got a response. I figured out my mistake and got it working. Would have been five stars if I could have gotten response from Lossigy.

Happy I purchased this for my golf cart!! The vendor was prompt sending it (early) and it is exceptionally well made ... :) My cart is lighter and quicker, plus the charge lasts longer.
