CHINS 48V 100AH Lithium Battery for Golf Cart with 48V 18A Charger, Monitor, Built-in Bluetooth 200A BMS, 48V Golf Cart Battery with 10.24kW Output, 1000A Peak Current

I had a friend recently convert his golf cart to one lithium battery. When my lead acid batteries finally started showing their age I bought this battery to put in my 48V Yamaha Golf Cart. A few things to note:First, this single battery is much larger than a single lead acid battery. It will not drop in and fit perfectly to the space where your old batteries were. You will need to make a special mount for it. For me, I put put a couple of blocks of wood together to make a level surface then used some ratchet straps to hold it in place. It weighs around 70 lbs, but since this replaced four lead acid batteries the each weighed about 70 lbs (probably 250 lbs +), this is much lighter!Second, this battery is essentially plug and play. It's nice not having to run a circuit of interconnected batteries like with the lead acid. Just put the correct wires on the correct terminals and you'll be in business.Third, you will need to get a new charger for this battery. The OEM charger and charging port will not work. I got the CHINS 48V lithium charger. It mounts to the terminals easily (these are the wires on top of the battery in the picture). It has a quick connector and charges extremely quickly (went from 50% out of the box to 100% in about 3 hours).Fourth, this battery has an app that will let you know important information, like charge level, battery temperature, discharge levels, etc. It has been convenient so far and I have no complaints. It is Bluetooth, so you must be in close proximity to connect.Last, while this battery didn't make my cart any faster (that's a motor thing), it did improve it's performance going up hills drastically. Before, my cart could only crawl up steep hills. Now it has nearly the same speed on the hills as it does on flat ground! I would chalk this up to not only being better performance from the battery, but also weight saving from losing the old heavy batteries. Also, after playing 18 holes on a course that is anything but flat (very hilly course in East Texas) this battery used 14% of it's capacity. That is with two guys on the cart, our clubs, and a big ice chest. So theoretically we could play 6+ rounds of golf before recharging. I could barely get two rounds in with the other.Needless to say, I am very impressed so far with this battery. It has greatly improved the performance of my golf cart, it was very easy to install, and I have no regrets. Yes it was a pricey investment, but well worth it. This will last longer and in the end save me more money over time. Hope you find this review helpful!

We bought this in August and I self installed it over the weekend following receipt of the shipment so this review is based on using the this set up for over three months now. We are completely happy, we will never go back to lead acid. We have owned this cart since 2012 and needed to replace our 3rd set of batteries. For roughly the same price as a new set of name brand lead acid batteries, I shed around 255 pounds off the cart and gained likely a minimum of 1600 more charge cycles. In other words, I expect to get 10+ years out of this battery. My range is now around 40 miles with constant uphill and downhill speeds. I am happy to also say the battery allows the speed limiter to regen charge the battery when going downhill. I gained a consistent 1 mph (gps verified) top speed too. The cart still has it's original stock motor and controller but larger diameter rims and tires with a lift kit and rear seat with heavy duty rear springs. With that said, we went from 18 mph (at best with a light load on a long level straight section or downhill) to a constant 19 mph no matter the terrain or load on the cart. Acceleration is noticably better too. It seems reasonable to assume all the measurable and seat of the pants improvements are probably a function of the weight savings and slightly higher, but constant voltage of this set up compared to the old lead acid set up.I did have to move a few things around and make modifications to the battery compartment and electrical harness. Don't let this scare you, even though I am not a trained golf cart mechanic, it was no big deal because I took some time to research what needed to be done. If you are considering this as a DIY project just make sure to take your time to understand what is involved before hand, you don't want to screw anything up or expose yourself to any unnecessary hazards. All the information you will need is available online from a variety of sources.I also added a LiFePO4 specific gauge so we can keep track of accurate state of charge, Amps, and Volts. It updates in real time so we can keep track in use. It is fascinating for me to see the amperage draw while in use. We have been able to learn a lot about the battery draw based on load, terrain and speed.Our cart feels lighter and has considerably more pep than before, the ride and handling are more crisp and the cart is better at carrying passengers. This is what a cart should be like from the factory. Finally, I also added an onboard 15 amp smart charger and routed the cord out to a convenient location for storage during use but also for easily access to plug it in for charging.I spent quite a few months researching battery makers and the set up I wanted to go with. I decided on a single 48V battery from Chins based on quality of materials, construction, and price along with reviews of the company from previous customers.The included Bluetooth software is basically functional, but has a hard time connecting with my phone. I do like the individual cell voltage read out, and the ability to monitor internal temps. It also tells me amp draw or charge along with battery percentage. With all that said, I find it much easier to rely on the above mentioned gauge. It is nice to see a very consistent reading between what the battery is reporting on the Bluetooth app and what the gauge is showing, so I am confident it is accurate.Thank you Chins for making this project possible for us. We are very happy with your product in our application.I plan to update this review occasionally over time.
