Cloudenergy 48V(51.2V) 105Ah LiFePO4 Lithium Golf Cart Battery Built-in 250A BMS,with Mobile APP,Touch Monitor and retention strap,6000+ Cycles,Perfect for Golf Carts(GFA48V-105AH With Charger)

We received the battery quicker than estimated and didn't waste time installing it. Removing the old batteries wasn't much of a problem and their absence left a lot of real estate for the installation. We used a thick piece of plywood to act as a central base as well as custom cut pieces on either side. We painted the bottom of the wood and hit it with two coats of polyurethane for some additional protection. I used some aluminum angle iron to create a solid base for the battery and cut slots for the ratchet straps to run thru. The actual piece of plywood was bolted to the frame using stainless steel hardware. One side of the compartment now hosts a 48V to 12 V converter and a fuse box. The other side hosts the charger, which was different in color/style than the photos listed, but appears to be of a higher quality. Running the connection from the battery, to the charger, to the new Noco plug was a cinch. We have a Club Card DS iq model with an aftermarket SELEX motor installed. YouTube showed us how to bypass the OBC easily (6-pun for us and we jumped white to blue). While we were at it we installed new LED lights, a USB charger, and a new horn. Too easy with the old batteries out of the way! The included battery meter is now improved from the included pics in that it comes mounted on a metal frame and installing it on the dashboard is easy. You can still use the Bluetooth capability to view battery status using their app as well. We fully charged the battery prior to installing it and will run it down to 50% twice prior to charging it daily, as per the included instructions. We felt the cart has more power in terms of get up and go and the overall performance has increased. We're very excited about the increased range due to the 100ah capacity as we use our cart daily to get about our town. So far very happy with our purchase and we'll be sure to update this review if anything changes.

Receiving Product Received an expertly packed box weighing over 100 lbs. It included high-density foam cut to fit the charger and battery. The box was made of double-sided cardboard and everything was clearly marked. Printed instructions were also included. Installing Battery Installing the battery was easier than I thought. To keep it concise, I've included a few photos of the installation process. The battery weighs 82 lbs and the charger approximately 12 lbs. Shedding 300 lbs of old lead-acid batteries from our Yamaha cart was very nice. The battery also comes with a display. Cart Performance I didn't expect an increase in top speed since the controller is limited to 14 mph, but the cart seemed to have more torque. Every accessory worked, and the cart drove well. Pros & Cons Pros: o Very happy with the battery system o Sheds significant weight compared to old lead-acid batteries o More torque in the cart o Display included Cons: o One small nuisance: to see the display, you have to press the on button when starting to drive the cart. The display turns off after a few minutes when the cart isn't drawing any current from the battery. Summary If you're serious about finding a great lithium battery pack for your cart, this may be the one. I have now installed two CloudEnergy Lithium battery kits, and I would buy from this manufacturer again as it has been a great experience. I rate this product 5 stars, even with the display not having an auto-on feature.

Replaced some aging lead-acid batteries in my Yamaha Drive/g29 48v cart. Range had dropped to only about 8-10 miles and it was lethargic up hills. Kit arrived quickly and well packed. Has everything you need and the total conversion only took about 2 hours start to finish. The battery and it's charger only take about half the space under the seat, freeing up a fair bit of storage room. The kit included 2 tiedown straps, not just one as shown, and the battery display also came with a mounting bracket, which was a nice bonus too. The cart is much more spritely. Acceleration is improved, gained about 3mph on the top speed, and much less speed loss when going up hills. The weight loss is also very noticeable. It actually made the ride a little jittery since the suspension was intended to carry 350lbs of batteries, but lowering the pressure in the tires helped smooth it out again. This cart has regen braking, which also still works as it did with the lead acids. No additional resistors or anything needed, which some other lithium replacements need or you forego your cart's Regen ability or add extra components. The display is handy to keep an eye on the battery level and how many amps your cart is pulling. This stock motor/controller pegs out at about 120 amps going up hills with 3 people onboard, and cruising at 20mph on flat ground, pulls 60-70 amps. 100 amp batteries would probably be ok for most stock carts, but having 200 amp continuous means there is a lot more headroom. Have had zero cut-outs. Range seems to be 40-45 miles or so. Was running it around the (Hilly) neighborhood all afternoon and still had 55%. Huge improvement from the tired lead acids. Even when they were new, you could only get about 15 miles and they would be down to 50%. The other benefit here is you can actually use 100% of the battery capacity, and you get consistent power the whole time, unlike leads that you shouldn't drain below 50% unless absolutely necessary, and performance noticeably fades as the battery drains. Build quality also feels better than expected. Hardware is good quality, no "rough edges", impressive for the price. Battery and charger are both fully waterproof, which not all of these options are. I just removed the stock charger connector, leaving the empty charge port flange. To charge, I just fish the charger's cord out and plug in an extension cord. Use at least a 14 gauge cord, as the charger pulls about 13 amps. Having the charger onboard is handy, so can top up anywhere there's an outlet. Full charge time is also as advertised. It takes about 1 hour per 20%, or just over 5 hours to go 0-100. Photos show before and after, a lot of extra space now. Update after appx 1yr- things had been smooth sailing, the first glitch was after about 9 months when the battery was low, but still showing about 20%. The cart suddenly died, the display instantly went to 0% and indicated output was disabled. I towed the cart back the last mile, and it charged up fine. I made a note to just not let it drop under 25%. Then only a few weeks later, it did the same thing though still indicating 40%. I'd also started having an issue with the charger occasionally not working, or it would charge for a minute or two, then stop. Unplugging and replugging would eventually get it going, but it was getting more finicky each time. I reached out to Cloudenergy support on their website, not expecting much. It'd been nearly a year, and I couldn't find any sort of explicit warranty given. Hey, it's a "cheap" battery, perhaps that was coming home to roost. To my surprise I got a response only a few hours later just asking for the Amazon order # and they'd get a new charger shipped out totally free. They also said a firmware update was available for the BMS that should help with the incorrect battery % readouts. They walked me through getting a (different) app to connect to the battery, and then using a special login so they could access it and do the update. We coordinated over Whatsapp and (Jovy) was very helpful and clear. Only a few minutes and it was done. Was just told to do a full charge to 100% to "reset" the calibration. They also said if the cart cut out again with plenty of charge indicated, to reach back out and they'd replace the entire battery, however they looked at all the cell voltages via the app and didn't believe one was bad and it was just a miscalibrated BMS. I have had the issue since and have run it down to 20% charge, so I'm inclined to believe that was it. So A+ customer support for sure. The new charger showed up only about a week later. Looking into this a little more, here's some nerdy details as to why that might happen. My cart has a step-down converter for the 12v lighting and accessories. This converter draws a small amount of power all the time, even if no accessories are on. (Unless the "tow" switch is flipped). It's not much, but adds up if the cart sits for several weeks without being charged. The BMS on these batteries sets 100% at a target voltage, then counts amp-hours out to calculate percentage remaining (as voltage drop on lifepo4 cells is very minimal across the charge range). However, it can't detect very small loads- so that tiny vampire draw of the 12v converter manages to "sneak out" a fair amount of juice over a few weeks, that the BMS is unaware of, resulting in it showing an erroneously high state of charge. The solution is to either wire the DC converter to only have power when the key is on, or flip the "tow" switch if the cart is going to sit for a while, just what I started doing. From what I read the newer firmware still mainly counts amp-hours out, but then does cross that against some predetermined average voltage levels, so if a discrepancy arises, it will err on the side of caution and report the lower as that slight phantom drain is fairly common in golf carts, particularly off-course ones that have extra accessories added and I'm not the first to have this issue by any means.
