Because 48V systems run at higher efficiency while using fewer amps, they can operate appliances more safely than lower voltage systems. A 48V system will not have to increase its amperage regularly to provide the same power level as a 12V or 24V system.

The golf cart market is evolving as more and more people are taking advantage of the versatile performance of lithium batteries in a golf cart setup. Deep-cycle flooded lead-acid batteries have been the most cost-effective means to power electric golf cars for decades. With the rise of lithium batteries in many high-power applications, GIANT 48V LiFePO4 batteries have many advantages.

What is a 200AMP BMS 'Battery Management System'?

Most cheaper lithium battery competitors will only have a 50AMP BMS, which will not give Aussie customers the ideal battery use capacity. A high-quality BMS system should be rated 100AMP and above, and the BMS is essential to getting a quality lithium battery product and the key to its long-term performance. It's a classic case of paying for what you get; the best quality lithium battery brands are the ones that cost money and have a superior size BMS. Many of our customers' applications require Lithium Batteries with higher surge currents. Therefore be careful because low-level rated BMS systems will take this away from users and can be dangerous. Unfortunately, our customers are too often burnt by cheap Lithium battery failures exposing themselves and their assets to harm.

The Giant 48V Lithium Deep Cycle Battery is designed to replace deep-cycle AGM batteries. They weigh only half of their AGM counterparts. In an emergency, this Australian Made lithium battery can be safely discharged to 100% DOD (Depth of Discharge), delivering twice the energy with a superior 200AMP BMS for maximum discharge capacity. This deep cycle battery charges your appliances between 4-8 hours and can be used in various other applications such as power tools, medical devices, and security systems. Aside from recreational activities, Giant Lithium Batteries are perfect for storing at home for backup power.


Charging your Lithium Battery

To charge your 48V 100AH Lithium Deep Cycle Battery you will need a 48v Lithium Charger

One of the main benefits of a 48V system is its increased energy efficiency. Higher voltage systems experience lower energy losses in the form of heat due to reduced current flow. With a 48V system, the current is one-fourth that of a 12V system, which significantly reduces energy loss.

We suggest adding an Ardent Lithium Charger

The 48V nominal voltage ensures low heat generation and high efficiency during high-power transmission. The modular design easily scales to meet a range of configurations—making it simple to tailor your energy requirements to specific projects. This battery meets the highest safety standards and has an exceptional lifecycle, optimized with proprietary manufacturing processes and cell architecture. The state-of-the-art battery management system (BMS) enables comprehensive protection features and real-time monitoring

I bought a GIANT 48v Lithium battery for my golf cart. I cannot recommend it highly enough. I easily removed the six old heavy Trojan wet cell batteries from my cart and easily connected the new lighter lithium. No more mucking about with topping up water levels and muck. The lithium is cleaner, lighter and more run time and power. It’s a no brainer! Dealing with Aussie Batteries was great. Fast delivery too.

Golf cart lithium battery

Have installed 48v lithium battery in a EZGO golf cart have had eight rounds so far and only uses about 15% capacity each round played three rounds without charging still 55% capacity left I think you’d easily get 6 rounds out of it before charging . The ardent monitor has failed not showing soc % after 5 rounds battery seems to be good

An impressive transformation

We purchased a second hand electric cart to make it easier to complete our daily sanctuary activities but quickly realised that new batteries were needed. We were recommended Aussie Batterries and Solar by a friend and got in touch with the sales team there. They were really helpful and promptly answered any questions we had. The Giant 48V lithium battery arrived when they said it would, despite the ongoing transport and supply issues that everyone was experiencing. Installation was pretty easy after modifying the holder for the new single battery. And the transformation has been impressive! Removing the 6 lead acid batteries and replacing it with the single Giant 48V battery has reduced the cart's weight by 120 kilos and added extra power. It is quick, drives well and is easy to monitor via the Bluetooth connected app. We get at least a week of driving out of it and over 30km of range despite the steep hills we take it. We highly recommend the Giant 48V battery and the team at Aussie Batteries and Solar
