Product Description

Ionic 48V 27Ah Lithium Deep Cycle Battery: Exceptional Value & Unrivaled Performance

lithium golf cart batteriesGolf cart motors can easily maneuver all day, when powered by our 48V 27Ah Lithium battery. And don’t forget about our Ionic Bluetooth App, which makes it easier than ever to track the life of your battery. All from your smartphone!

The Ionic 48V 27Ah Lithium Deep Cycle Battery is one of the most advanced lithium deep cycle batteries available on the market. It also comes with an impressive 11-year battery warranty to ensure your satisfaction and peace of mind. We’re in it for the long haul.

Features World-Class Safety Measures

The Lithium 48V 27Ah Battery is ideal for high power needs and deep cycle systems. All of our Ionic batteries feature an integrated microprocessor-controlled battery management system (BMS). Ever heard of a smart battery? This is it! Our advanced system monitors critical operating parameters such as voltage, current, & internal temperatures. Functions that are vital for safe charging and discharging. So sit back and relax…your battery can take it from here.

Need to connect more than one battery? No problem! Ionic deep cycle batteries can be connected in parallel, as many as needed for further range. A single 48V 27Ah can expect a range up to  ~12 Miles with our Ionic single 48V27Ah battery.  Put another 48V27Ah in parallel and with two batteries expect a range up to ~ 24 Miles.

Built To Outlast The Competition With Longer Life & More Efficiency

These batteries are designed for high performance aftermarket golf carts that boast maximum power and acceleration. Another feature that sets them apart from nearly every other golf cart battery is an incredibly high discharge current. We’re talking up to 500A discharge on a single battery. Put two batteries in parallel and you’ll have over 1000A discharge on a 48V system. Put more batteries in parallel and you guessed it…even higher discharge current! And keep in mind, these batteries aren’t just for high performance golf carts, but ALL regular 48V golf carts. On average, our 48V 27Ah battery lasts a whopping 3,000 to 5,000 cycles. This equates to roughly 10 years of battery use. Cycles are the number of times your battery is fully charged and then discharged.

Most lead acid batteries have a usable capacity of 50-60%, meaning you have to charge them much more frequently. Ionic Lithium LiFePO4 batteries have a usable capacity of 99%. Talk about efficiency!

In addition, Ionic batteries can perform well in a wider range of temperatures. They can discharge between –20°C to 60°C (–4°F to 140°F) and charge between temperatures 0°C to 45°C (32°F to 113°F). And don’t worry, if your battery is too cold to charge, the system will automatically recognize this.

Incomparable Weight To Power Ratio

Our Ionic Lithium 48V 27Ah battery measures: 10.2″ (L) x 7.1″ (W) x 10.4″ (H). And it weighs a very manageable 33.1 lbs. Unlike lead-acid batteries that come fixed, our 48V 27Ah battery comes with 3/8th thread terminals that allow it to be installed in any direction.

With an impressive 1-3% monthly discharge rate, your cycle will go much further. On the other hand, lead-acid batteries usually discharge 30% per month.

48V 27Ah Battery Common Uses

Looking for a battery that’s incredibly lightweight and compact? Our 48V 27Ah battery may very well be your best answer! If you’re looking to propel your golf cart or other high power 48V systems for solar or telecom look no further.

More of a solar enthusiast? It can also be a great fit for solar setups, small commercial equipment and more. Learn more about your lithium 48V 27Ah battery in our blog post, The Best Golf Cart Battery: Lithium Or Lead Acid?

Other important things to note: 

  • The maximum charge voltage for our 48V 27Ah battery is 58.4V, with a 42V discharge cut-off voltage.
  • The max charge current is 30 amps and the max discharge is 150 amp /500 amps (3s).
  • Solar chargers can be used! (Not sure which charger is best? Check out this post.)
  • Most standard lead-acid chargers without a “Desulfate” mode can be used (so long as the current levels do not exceed the lithium battery charge requirements).
  • Your 48V 27Ah battery can be completely charged with a standard lead-acid charger that achieves 57.6-58.4 volts.
  • Chargers with a voltage of fewer than 54.4 volts will only charge the battery to 50% capacity or less.

Great purchase

I like this Lithium battery. It’s light weight. Charges quickly and lasts a long time. I no longer have to add water to my golf cart batteries. I use my iPhone to monitor the charge level.

48 volt golf cart battery

So far I really like the battery. The difference of 408 lbs of the lead acid batteries and the 33 lbs of the ionic battery gives me extra “zoom”.

Hoping for the Best

My review is by no means complete let’s be clear on that. The reason for 3 stars is more due to the state of our country and most likely not on the shoulders of Lithium Hub or Ionic although I do have some reservations. I ordered the battery in February and did not receive until June. My credit card was charged but no battery for quite some time. I believe the card shouldn’t be charged until the product is available but maybe that is on me. The only negative I really have is no instructions on instillation (maybe something online but I couldn’t locate) and the website claims it will fit my battery tray, it does not. I made adjustments and believe it is somewhat secure. Ok, enough with negative comments and would like to say every time I called the service was top notch, even talking to a higher level manager at one point. Packaged great and the battery is 1/10th of what I had previously! Figured out what to do with all the previous wires and got it hooked up. The cart ran like a charm. Drove for about two miles, checked the app, and unbelievably it was still at 100%. Hopefully, it lasts 11 years and everything will be GREAT! 5 stars for product and 3 for the state of the World that we live in.
