Low Long-Term Cost

It is estimated that most electric golf carts, are powered by traditional lead-acid batteries despite the advantages of rechargeable lithium batteries. The primary reason for this stems from the one major disadvantage of lithium-ion batteries: They have a high upfront cost. However, when you factor in performance and lifespan, lithium-ion batteries are a much more cost-effective choice.

Although lithium-ion batteries are more expensive than standard batteries, they are rated to survive up to 5,000 charge cycles with a full discharge each time while lead-acid batteries can only go through about 500 cycles at an 80 percent discharge. This means that lithium batteries will last up to ten times longer. With traditional batteries, or used golf cart batteries, you will need to replace them every two to three years, but with lithium-ion batteries, you may never need to change them out again. The lifespan of many of these batteries actually exceeds the operational lifespan of many golf carts

Improved Performance

While a lower lifetime cost is enough to drive most people to replace their lead-acid batteries with lithium-ion batteries, the latter also delivers improves performance. Because lead-acid batteries discharge at a slower rate as the charge depletes, they stop producing enough voltage for operating a golf cart when they are still 30 percent full. This is wildly inefficient and it drastically reduces the range of the vehicle on a single charge.

In addition to increasing a vehicle’s range, lithium-ion batteries increase its speed and carrying capacity because they are so much smaller and lighter than lead-acid batteries are. Lithium-ion batteries are about one-half the size and one-third the weight of standard batteries.

The reduced weight increases the vehicle’s range even more, especially when driving uphill or on rough terrain, and the golf cart won’t track through the grass or tear it up when it is wet. Furthermore, a lighter vehicle puts less stress on the brakes, improving braking distance and increasing the time before they need to be replaced.

Lastly, lithium-ion batteries charge much more quickly than lead-acid batteries do. The average time it takes to recharge a golf cart after 18 holes is eight hours, but lithium batteries can reach 80 percent capacity in only one hour and obtain a full charge in only 2.5 to three hours.

With solar shore tied charging is not needed

Other Benefits of Lithium-Ion Batteries

When you replace the standard batteries in your golf cart with lithium-ion batteries, you can expect to experience the following additional benefits:

No maintenance – Lithium-ion batteries have no water levels to check, have no build-up on the connectors and do not corrode.
Environmentally friendly – Because they last so long and do not degrade, lithium batteries do not need to be frequently destroyed or recycled.
Safe – Although early types of lithium batteries were prone to overheating, new versions are as safe as or even safer than standard batteries.

A sophisticated State-of-the-Art Battery Management system monitors each of the 15 batteries and uses 15 individual chargers built in.

this totally balances the charge precisely.

Hi Bob,
Wow, sounds impressive, but as you say the only real drawback is the upfront cost. 👿👿

Somewhere in one of the threads you say you have negotiated with the supplier and almost halved the cost now to us in TV. 👍👍

How much would a full set cost now if I wanted to change my batteries today?
