Vatrer LFP Battery Transforms EZ Go Golf Cart

Assist CleanTechnica’s work via a Substack subscription or on Stripe.

Vatrer is a Chinese language firm that manufactures a wide range of LFP batteries to switch the lead-acid and flooded batteries utilized in many purposes in the present day. No matter your voltage or amp-hour wants, Vatrer has the precise product on the proper worth.

Just lately, the corporate provided to produce one in all its batteries to somebody on the CleanTechnica workers who owned an electrical golf cart. Since I used to be the one one to qualify, I turned the recipient of a 51.2 volt, 105 amp-hour Vatrer battery with a complete capability of simply over 0.5 kWh. All I needed to do was set up it and go. Such are the benefits of writing for a prestigious on-line clear vitality publication!

A number of years in the past, my spouse and I purchased a manufactured residence in a seasonal campground in Connecticut. Golf carts have turn out to be a fixture of campground residing. They bring about us to the seaside and the laundry room. They decide up our Amazon packages on the workplace and take us to the restaurant for dinner. We inherited a drained gas-powered cart with our buy, however since we’re each sturdy advocates for electrical transportation, we traded it for a 48 volt electrical EZ Go TXT inside weeks of shopping for our unit.

Fuel-powered carts have most of the identical upkeep points as typical automobiles. They’ve a small battery and starter. They’ve piston rings and valves and clutches, all of which put on out and want consideration every so often. Conserving their batteries from freezing within the winter is a problem. In our campground, an area fellow comes most weekends to service the carts and there’s by no means any lack of labor for him to do.

Our cart, which we name Pumpkin, makes use of six 8 volt lead-acid batteries for a complete of 48 volts. We shortly realized there have been upkeep challenges with battery electrical carts as nicely. The batteries must have water added regularly, and never simply any water — distilled water solely, thanks very a lot.

A number of the fill holes for the three batteries within the rear are hidden below the bodywork of the cart, so that you want three fingers so as to add water to them — one to raise the little flap that provides entry to them, one to carry the container with the distilled water in it, and one to information the water into the right gap with out spilling most of it on the bottom.

Even with correct upkeep, these batteries don’t final eternally. 4 years of service is regular, 5 years in case you are fortunate. Additionally they have to be charged over the winter to maintain them from freezing. My batteries developed vital corrosion at all the 12 battery posts. After 4 years, I needed to change all of the battery cables (thanks, Amazon) and I discovered a lot of the small constructive and destructive ring connectors for auxiliary energy and charging turned so eaten away that they snapped off simply — often whereas filling the batteries with water.

By the top of final summer season, the lead-acid batteries in Pumpkin have been displaying indicators of sporting out. They struggled to go up hills, the terminal corrosion was getting progressively worse, and so they appeared to wish water extra regularly. Changing them with new lead-acid batteries was projected to value a minimum of $1,800. I received one quote of $2,485. Yikes!

The Vatrer battery was delivered earlier than I arrived this summer season, so along with opening up the modular residence and fixing a couple of issues that broke over the winter, then cleansing the home from stem to stern, engaged on the cart was not my high precedence. I known as Brandon at Protek Autoworks in Somers, Connecticut, the place we purchased Pumpkin a number of years in the past. He took the cart to his store, put in the battery, cleaned and serviced Pumpkin, and had it again to us the following day.

Earlier than & After

Brandon had his work minimize out for him. The photograph above reveals the outdated batteries. The one under reveals the brand new Vatrer battery put in and able to go. He and his household construct race automobiles and have a full metallic fabrication store onsite. This was his first lithium-ion battery conversion, so he frolicked on the web and on YouTube educating himself in regards to the course of. The completed product reveals his meticulous consideration to element.

Brandon additionally put in the show display screen, so it’s clearly seen to the driving force however not liable to being bumped or damaged in regular use. The display screen shows state of cost and anticipated vary for a given throttle opening. As an illustration, it should inform you that at huge open throttle, you’ve got sufficient vitality for about 4 hours of operation. We nearly by no means use greater than half throttle, so I anticipate needing to cost the battery solely about as soon as a month. The battery has a ten yr design life and is rated for 4000 cycles. The best way I take advantage of Pumpkin, meaning my grandkids will in all probability nonetheless be utilizing it when America celebrates its three hundredth birthday.

All carts have lights and a horn — equipment that run on 12 volts. As I used to be doing my very own analysis (see video under), I discovered a variety of chatter about putting in a 48 to 12 volt converter. With Vatrer, there isn’t a want to fret, as a result of the voltage converter is included within the package deal.

Brandon put in it and dressed the wires in a really skilled method. The package deal additionally features a 20 amp charger that takes a pair hours to convey the state of cost again as much as 100%. One other function constructed into the Vatrer battery is an app that permits house owners to watch the standing of the battery remotely. That may be a good function to have, as it should enable me to maintain tabs on issues through the winter.

My spouse and I even have a 2017 Chevy Bolt with the second-generation battery that GM created along with LG Power to deal with the battery fires that plagued early examples of that automobile. Yearly, it spends the autumn, winter, and spring beneath a automobile cowl, ready patiently for us to return. Whereas it’s idle (we do put a trickle charger on the 12 volt battery), it loses about 5 % of its cost, so I’ve realized to not be too involved about lithium-ion batteries shedding their cost throughout lengthy durations of inactivity.

The Vatrer battery arrived with 52 % SOC. I estimate it was dormant for greater than a yr after it left the manufacturing unit, received shipped throughout the ocean, sat in a warehouse, then received trucked throughout the continent to my campground, the place it stayed for a number of months earlier than it received put in, so I’m not involved about it shedding its cost subsequent winter.

With the Vatrer battery, there isn’t a difficult shutdown process. There’s a button on the precise facet of the battery. Push it to activate the battery and it glows shiny inexperienced. Push it once more, and the battery shuts down. The corporate recommends turning the battery off if it is not going to be used within the subsequent 5 days.

My tenting group has a whole bunch of campsites constructed into the facet of a mountain. Accessing the higher websites requires fairly a little bit of vitality. Pumpkin used to decelerate noticeably going up steep grades, however now it acts like they aren’t even there. Prime pace is identical as with the outdated batteries, however there’s reserve energy within the Vatrer battery that was not accessible earlier than. At present, Pumpkin drives like model new and I couldn’t be happier.

I need to give a shoutout to Brandon at Protek Autoworks. He was attentive to my wants, and his work is neat {and professional}. He might be reached by e-mail or you may textual content him at (860) 749-3780. In case you are anyplace close to Somers, Connecticut, and want service to your golf cart, he’s the one to name. Thanks, Brandon. Nice job!
