Navitas AC Motor Controller | Golf Cart Navitas Upgrade | Navitas Controller

Many customers ask about increasing the speed of their golf cart. This kind of upgrade is done through the golf cart’s motor controller, a service that we offer. One of the industry’s best controllers is the Navitas AC motor controller, which we sell both by itself, and offer installation at our service center.

About Navitas AC Motor Controller

The Navitas AC motor controller can be programmed to increase the speed and power of a golf cart, as well as offer more miles per charge, and is small and easy to install. They are designed for various types of golf carts, including Club Car, EZGO, Yamaha, Star, Advanced EV, and more.

Golf Cart Battery Charging | Battery Charging Tips | Golf Cart Battery

Golf cart battery charging, in reference to standard lead-acid golf cart batteries, isn’t always as simple as just plugging the cart in or periodically refilling the water levels of the batteries. However, optimizing the performance and getting the most life out of the battery as possible can require additional steps to make sure that the batteries are functioning the absolute best they can.

Golf Cart Battery Charging Algorithm

golf cart battery charging, battery charging tips, golf cart batteryMost golf cart chargers use a 3-stage charging algorithm, consisting of a bulk charge stage, absorption charge stage, and finish charge stage. This algorithm determines how much power returns to the battery at various intervals, in order to make sure it is not undercharged or overcharged. During the bulk charge stage, about 80% of the discharged battery power will be recharged, usually taking around 4-8 hours depending on how low the battery charge was. The second stage, the absorption charge stage, the charge current slowly decreases until the 100% of the discharged battery power is recharged – however, this does not mean the battery is fully recharged. The final stage, the finish charge stage, slightly and safely overcharges the battery to account for efficiency losses. When using the right size charger, the battery is safely overcharged without damage.

In order to fully optimize the performance and life of lead-acid batteries, it’s recommended that the properly sized charger for the amp-hour (AH) capacity is used. The bulk charge stage of the charging algorithm should have a charge current of approximately 10% of the 20 hour capacity of the batteries, and the finish charge stage should have a charge current of about 3% of the 20 hour capacity of the batteries. The 20 hour capacity can be found on the battery’s sticker.

The voltage output of the charger should be sized to the number of cells connected in series in the battery pack. You find this by taking the number of cells connected in series times 2 volts per cell. A battery pack with 24 cells connected in series will use a 48 volt charger. The charger should also be able to provide an on-charge voltage of at least 2.6 volts per cell. A 48 volt charger for a 48 volt battery pack, therefore, should be able to provide at least 62.4 volts on a charge in order to completely charge the battery pack.

Depth of Discharge Meaning

When reading about lead-acid batteries, you may come across the term “depth of discharge”, or DOD. Simply put, the DOD refers to how much energy is cycled into and out of the battery on a given cycle, and is expressed as a percentage of the total capacity of the battery. For example, a battery that has been drained by 30% has a 30% DOD, and 70% of its capacity remains. It’s important to understand DOD because the more frequently a lead-acid battery is discharged and recharged, the shorter its lifespan will be. When the battery percentage gets down very low and is then recharged, this can shorten the life of the battery as well. To help with this, many battery companies recommend a 50% DOD. We have more on our 50% charging recommendation for our rental carts further down below.

Golf Cart Battery Charging Tips

golf cart battery charging, battery charging tips, golf cart batteryWhen charging lead-acid golf cart batteries, it’s important to do it in a well-ventilated area. One of our recommendations is also to lift up the seat that covers the batteries – in 4 passenger carts, they are most often under the front 2 seats, and 6 passenger carts mostly have them under the middle row of seats – either before or directly after plugging in the charger. This is because when a lead-acid battery system is plugged in, as it begins charging, it can release hazardous fumes from the chemicals inside the batteries. Build-up of these fumes under the seats can be dangerous, so to avoid this, either leave the seat up as the batteries charge, or lift the seat and allow any possible fumes to clear out and ventilate before putting the seat back down.

Charge batteries as soon as possible after discharging. As a golf cart sits idle, even if it’s not on, the batteries will slowly lose charge, just like your phone might when it sits for a while without charging. Therefore, to keep your batteries charged and possibly increase their life cycles, plug in the cart after use and make sure to unplug the charger once it’s fully charged. Use the right sized charger to prevent overcharging as well. Check your electrolyte levels monthly and keep your batteries filled –  use distilled or deionized water and cover the plates before charging, but don’t fully refill the batteries until after they are done charging to prevent overflow.

If storing your golf cart longer than a month, fully charge the batteries prior to storage. We have another blog with more on golf cart long-term self-storage, with additional tips for storing your golf cart on your own property.

Our 50% Golf Cart Battery Charging Recommendation

When renting one of our street legal golf carts, we always recommend that customers charge the batteries when the cart starts to get to around a 50% charge. Generally, during rentals, people use the carts during the day and plug them in overnight, and if the battery percentage doesn’t drop too low, most of the time the cart is fully charged by the next morning. When lead-acid batteries get too low, they take a much longer time to recharge back to 100% – depending on the cart, some lead-acid batteries can take up to 16 hours to fully recharge if the batteries were run down too low. Some carts, mostly older ones, won’t even respond to a regular golf cart charger if the battery is too low, and need to be supercharged – similar to jumping a car – before they can be plugged in to a standard charger. If the battery percentage is kept monitored and does not drop too far below 50%, the batteries will most often take about 6-8 hours to fully recharge. This is why we recommend plugging the cart in at night.

NOTE: Watch for Surface Charge

Sometimes, you may plug in a golf cart and after only a couple hours, the state of charge meter may say the cart is 100% charged. However, this is only a surface charge, meaning that it appears that the batteries are fully charged, but have not had a chance to deeply absorb all the power that they need. This cart will drive for a short time with regular battery charge decay, then suddenly begin to drop more rapidly if the battery has only had this beginning charging stage. To make sure the battery is fully charged: in our Advanced EV carts, the onboard Eagle charger will have a fan that comes on when the cart is plugged in, and when completely, deeply recharged, the fan will shut off. For carts that don’t have an onboard charger with indicators such as this, the charger will often give an indication with a light that the golf cart is fully recharged. NOTE: Not all chargers or carts make a noise when they are charging. The charger should give an indication with a light or something similar (a meter, for instance) that the cart is charging. To make sure the charger is working, you can always test the voltage of the batteries before and after charging with a voltage tester.

Golf Cart Battery Storage | How to Prepare a Golf Cart Battery for Winter

As the weather begins to get colder and the golf carts begin to roll into storage, it’s important to know how to maintain your golf cart batteries for the winter season. Sunny Isles Golf Cart provides a detailed guide on how to prepare a golf cart for long term storage; today we talk specifically about golf cart battery storage, especially in the winter. The key to maintaining the longevity of lead-acid batteries through the winter is proper storage.

The process of preparing for golf cart battery storage is similar in both the summer and winter seasons, but one thing that remains constant is the importance of fully charging your battery before putting the golf cart into long-term storage. The reason for this is because leaving them discharged in cold weather can actually cause the electrolyte inside to freeze and therefore expand, which could potentially crack the battery case and cause a leak or battery failure. When a battery is not charged, its freezing point is about 20 degrees Fahrenheit, while a fully charged battery has a much lower freezing point: approximately -80 degrees Fahrenheit.

If the weather is not too severe and you’re not putting your golf cart into long-term storage, there are still procedures to follow for using your golf cart in colder temperatures. Cold weather causes the batteries to charge slower, and reduces the battery’s capacity. In this case, it’s extra important to make sure the battery is fully charged before driving the golf cart – a common mistake made is plugging in the battery and assuming it is fully charged, not knowing that charging slows in colder weather, and therefore draining the battery further with every drive. In order to check the charge of your batteries in cold weather, you’ll want to take hydrometer readings of your battery’s cells and use the correction factor of subtracting 0.004 (four points) from your reading for every 10 degrees below 80 degrees Fahrenheit (the optimum temperature to take a hydrometer reading). A fully charged golf cart battery should have a hydrometer reading of approximately 1.270. For example, if the outside temperature is 50 degrees Fahrenheit, and your hydrometer reading returns as 1.200, you’ll want to subtract 0.12 from this reading; your correct reading would therefore be 1.188, which means the battery is less than 50 percent charged. It’s extra important to fully recharge the battery before driving or putting the golf cart into storage, as a golf cart that drops below 50 percent charged can be more difficult to fully recharge.

Another tip we recommend for driving a golf cart in colder weather is using one of our golf cart enclosures – we have a blog detailing the various enclosures we sell for our Advanced EV or Icon® golf carts, available for purchase on our parts website!

How to Prepare Your Golf Cart for Long-Term Self-Storage

If you would prefer to store your golf cart on your own property rather than in a storage facility, there are several important steps to take to ensure that your golf cart stays in top condition during the off-season or time it’s not in use. Even when storing your golf cart for long periods of time, there is more to it than simply tucking the cart away in a shed for months at a time. Golf carts still require periodic maintenance when not in use, but following the right guidelines to storing your golf cart will keep it preserved and ready for when it’s time to be brought out again.

Battery Preparation

When preparing your golf cart for storage, you’ll want to first perform some basic battery maintenance. Begin by disconnecting battery cables, and clean any corrosion from the cables and battery by using a mix of baking soda and warm water (or white vinegar and water) – baking soda neutralizes acid corrosion. Fully charge the battery, as batteries will naturally self-discharge when not in use. When disconnecting the battery charger, unplug it from the AC outlet before unplugging it from the cart. Using only distilled water, refill the batteries, making sure the cart has been fully charged. Do not refill the batteries before fully charging your cart, as this can lead to electrolyte overflow.

Turn the key switch off to turn off everything on the cart, and depending on your cart, you’ll have either a Run/Tow switch or a Run/Maintenance switch. Flip this switch to “tow” or “maintenance” in order to reduce battery discharge and fire risks. Finally, disconnect the main positive and negative connections – it’s recommended to tape the connections together in order to not forget where they go.

You’ll want to periodically check in on your charge and water levels – especially in warmer climates, the water levels can slowly decrease due to evaporation, and batteries will self-discharge when left unused for extended periods of time. It’s recommended to return to your cart every 2-4 weeks and check these levels – fully recharge and refill the batteries as needed.

Tire Checks

Before putting the golf cart in storage, you’ll want to inflate your tires as high as possible without over inflating them. When the cart is stationary for long periods of time, the tires naturally deflate from the weight of the cart, possibly causing damage to the tires like flat spots. When checking in on the cart as recommended, inflate the tires every two weeks and move the cart slightly, applying pressure to a different part of the tire.

Another option is storing the golf cart off the ground – raise the cart up onto jack stands, which will take pressure off the tires and ensure that no flat spots will form.

General Cleaning

Even in the best storage, moisture will still be produced. Inspect your cart to make sure there are no rust spots, and if there are, cover them with fresh paint. Rust spots can increase from moisture in the air if left untreated, and any other markings will also worsen with extreme temperatures. Be sure to remove any crumbs that may be on the seats, as they can grow and harbor bacteria in the time the cart is stored, and make sure to clean the flooring and upholstery to prevent any possible molding. Remove any rugs or carpets, cut and polish any scratches, and replace spark plugs if needed. Other things to clean include any dirt or grime, bird or other animal droppings, mirrors, fuel, air, and oil filters, and cables and connectors.


An important tip to remember is to leave the cart in neutral when storing it, and if storing it on the ground, keep it on a level surface and surround the wheels with bricks or other heavy objects to keep it from rolling. Do not keep the parking brake engaged – this can damage the cart.

Most golf carts will fit in a 10×10 enclosed space – placing the golf cart inside is critical and will prevent any damage that could be caused by harsh weather and below freezing or exceedingly high temperatures. A garage is a good option, although it can take up space that may be needed for cars, so storing it in a small shed is another ideal choice.

Even though the cart is inside, always use a protective cover to keep dust and dirt off the cart. If you don’t have a cover specifically for golf carts, a large canvas cloth will suffice – the most important thing is simply making sure the cart is covered.

Even when not in use, your golf cart still needs periodic maintenance, so it’s important to follow these steps to ensure that your golf cart is sufficiently prepared for storage and regularly checked in on, so when it comes time to use it again, it’ll still be in top condition.
