48V 105Ah Lithium Golf Cart Battery Built-in Smart 200A BMS with Touch Monitor Mobile APP 4000 Cycles Rechargeable

This was installed in a 48V Club Car Precedent Golf Cart. First of all, it's fairly easy to install if you are handy. Saved me several thousand vs having the local golf cart company do it. The golf cart runs a bit faster with it, no acid to leak and the handy screen shows everything you need to know. Some things to note: Like all larger lithium ion batteries, this has a batter management system (BMS). This is to prevent it from overheating and melting on you, but also to prevent other disasters. Downside is that it will also shut everything down if the battery is at risk. Meaning if your voltage runs under the specified limits it will shut down so you cannot let this power down for long periods. Well, I had a medical procedure on my heart and was gone for about a month. My golf cart was NOT plugged in (don't think about these things when you're going to the hospital). Luckily I am back and alive. But my battery was dead. Completely dead. No charge from anything. Emailed customer support asking what I could do. Didn't expect much. However, Joseph responded and was amazingly responsive and helpful. Joseph worked with me on getting the battery replaced even though it wasn't their fault. The manual clearly states to turn the battery OFF to preserve its life if you're not going to use the golf cart for over 5 days (you can go longer but 5 days to be safe). Either leave it plugged in (the BMS will prevent overcharging) or turn if off by putting your golf cart in "TOW" and pressing the green ON/OFF button. If you can leave it plugged I bet that's the better option. Based on my experience with both the product as well as the amazing customer service, I give this product 5 stars. Very well made, works awesome, and great customer service! Read more

I installed this myself to replace six dead lead 8v batteries in my Icon golf cart. I was skeptical on whether I could handle the install myself and I was pleasantly surprised. The battery, charger, and LCD and wires and such are expertly packed and come complete with easy to understand instructions. The battery is heavy, of course, but comes with handles to easily accommodate placement in the battery tray. I kept my old voltage converter and replaced the old charger with the new one. I ran the LCD wires under the cart and mounted it on the front dash. The install was rather quick after I learned I had to bypass an icon interlock function that prevented the cart from moving when it thought the charger was connected. Overall, this is a very good value for the money, the cart works great and has improved speed and acceleration. We can also go an entire weekend without charging. The charger has a fan on the side so be sure to mount the charger so the fan and vent have free air flow. I even accidentally purchased the 72v lithium conversion kit before this one and Vatrer worked with me quickly and efficiently to return the accidental purchase without issues. I'm very impressed with the product and with a 5 year warranty, you can buy it with confidence. Read more

The Vatrer system was acquired for conversion of a 48-volt 2013 EZGO RXV to lithium. Important considerations were the high capacity of 105 Ah, the high steady current limit of 200 amps and the 400-amp surge current for good acceleration. It may be that high current capacity helps support regenerative braking. The second-most-vital component of the kit was the on-board charger. The battery was half charged on delivery. Prior to installation, the charger was attached; and it provided the advertised 22 amps of current initially. This tapered off to about six amps as the charging process approached completion. The third component of the kit was a display unit. This turned out to be a standalone unit that could be used prior to installation. It required no connection to any of the cart wiring. A button push is needed to turn on the display. The display switches off automatically after a delay when operating the cart; it does not seem to switch off automatically when charging the battery. The display offers touch switches for turning on and off either charging or discharging the battery. The display satisfies all genuine needs; it leaves me, however, with an urge to add a simple, full-time display of just the battery voltage. The final component is a phone app that connects to the battery via blue-tooth. It duplicates many of the capabilities of the physical display. The blue-tooth connection is available even when the cart key is off. The information packet is limited and generic. This means that the owner must devise his own mounting system. I used three pieces of 5/16” plywood to level the original, forward battery slots and then covered that area with a larger piece of ¾” plywood. A pair of metal mounting rails would have worked just as well, given the sturdy brackets on the battery unit. Other than mounting provisions, the system became operable by disconnecting the factory charging port entirely, connecting all other existing battery wires plus the new charger, and making a small wiring change related to releasing the RXV brake. The kit packet did not describe the last item. For convenience of use, I replaced the factory charging port with an AC connector and escutcheon plate. The Vatrer kit came with eight 8-mm bolts, stainless steel, a bit less than an inch long with lock washers but not with nuts. There were two similar, shorter bolts, which I used at the battery terminals. There was a red and a black plastic terminal cover. I’ve played three rounds of golf so far, using less than 20% of the battery capacity each time. Cart acceleration is smooth and strong and easy to modulate. I anticipate good performance, while eliminating most of the maintenance headaches associated with lead-acid batteries. Read more

I bought this battery 9/2024 to replace my 6 - 8volt lead acid batteries in my golf cart. The conversion was easy with the help of YouTube. The performance is amazing, so much more power and pickup than my old battery. Things were great until it died twice on me - first at 50% then again at 40% charge. I emailed vatrer. They responded quickly and advised that I charge to 100% then discharge to 0. I was able to get it to 40% twice then it left me stranded again. So, I figured I spent $1,700 on a battery that I’ll have to charge daily. It was still better than what I had previously. I contacted support one more time, told them I was unhappy and they sent me a new battery. I noticed the charger was updated from the one I got a year earlier. It performs perfectly. Support is great and I recommend this battery. It’s such an improvement over the lead acid batteries. Read more
