Our InSight Series™ 48V lithium iron phosphate battery is a GC2 sized drop-in replacement battery that delivers high-quality performance, power and precision. This 48V 30 Ah battery was designed specifically for golf cars, utility vehicles, LSVs and AGVs.


InSight batteries are drop-in ready and easy to install, just connect them in parallel for the capacity you need. No need to modify trays, no complicated connections, and no heavy lifting. We recommend using our Battery Spacers to fill the empty battery spots so you can use the existing battery hold-downs that come in your vehicle. These can be purchased on our website. If you do not use our Battery Spacers, please ensure your InSight batteries are securely held down.


They’re also scalable, so you can provide increased power and energy (up to 300Ah) as needed. InSight batteries are connected in parallel (up to 10) which means you have the freedom and flexibility to use the right amount of batteries for your equipment, typically two to six batteries.


InSight batteries also feature an elegant BMS that provides precision balancing within a battery and between batteries in a parallel system without the need for charging batteries individually. In addition, our proprietary software determines and manages regenerative currents – unlike any other battery solution - avoiding unnecessary battery disconnects.


With InSight, you get unmatched quality and performance, from the inside out. It’s the only lithium battery like it on the market today!

Using these batteries in a six-seater EZ Go passenger golf cart. Excellent batteries, but they have a few unique features that take a little getting used too. But overall, I like the batteries and a significant improvement over lead-acid batteries.

Rick R.

Purchased two 30AH Insight Batteries and Battery Monitor on-line/direct. I was promptly contacted about the cordset desired for the Lester Electrical Summit II charger included as a promotion and all items were meticulously packaged arrived in only 3 days by UPS ground. Tracking and Product Installation instructions were included in print and by e-mail. A few remaining questions were promptly answered by phone and e-mail.

I completed installation on a Club Car Precedent in about a day including some custom mounts. I opted for this approach rather than fitting "empty" filler batteries. These batteries are truely state of the art "smart batteries" with on-board management and SOC indication. Their initial performance has been outstanding. The weight reduction of 400 lbs to 88 lbs (with charger on board) makes the cart feel light and fast. There is no going back to high maintenance lead acid batteries which are really a pain to deal with.

I have yet to test the range of the unit, but I feel confident already that even though the initial cost is higher, these Lithium batteries are the best life cycle proposition for this application. Kudos to Relion.

Frequently Asked Questions

What is the InSight Series?
The InSight Series™ is the newest addition to the RELiON Battery product family. InSight is the first scalable LiFePO4 drop-in replacement battery requiring no extra hardware when connected in parallel. InSight makes connecting batteries easy using parallel connections to increase the available capacity for longer runtimes. Just connect and go! InSight also boasts several intelligent features that make it truly unique, including a SuperSmart BMS that allows for Bullseye Balancing™ through innovative algorithms ensuring precise balancing between cells.
How do I determine the number of InSight batteries I need?
The number of InSight batteries needed will depend on the range you want and the brand of the vehicle. The more InSight batteries you use, the more range you will acquire. For Club Car and E-Z GO cars we recommend two or more InSight batteries. For Yamaha cars, we recommend three or more InSight batteries. If you have a car outside of these three brands, we recommend three or more InSight batteries.
How do you install InSight batteries?
InSight batteries are super easy to install. Because they are a GC2 size battery, they’re designed to fit perfectly in your golf car. Simply remove your old batteries, drop-in your new InSight batteries, connect them in parallel, connect the CAN cables that come with your battery then turn your batteries on via the wake-up button. There’s no tray modifications and no extra components needed. We do recommend you use our spacer batteries in the empty battery slots so you can use the existing battery hold down that come with your vehicle.
Can InSight batteries be connected in parallel or series?
RELiON’s InSight batteries were designed exclusively to run in parallel. For starters, each InSight battery is 48 volts. This simplifies installation and makes each unit more reliable than the normal method of connecting several 12 - or 24 - volt batteries in series. At 48 volts each, you need fewer batteries for your golf cart. But that doesn’t mean you can’t use more. Up to 10 Insight batteries can be connected in parallel, giving you up to 300 amp-hours. Because they are in parallel, if any one battery goes offline, you will not notice any difference in performance, only duration. A parallel connection extends the reliability of each individual Insight battery to the entire array, giving you more power, more capacity, and less to worry about when driving your golf cart.
How strictly do I need to follow the recharging limits?
The short answer is “not very.” Our specs call for the batteries to be recharged to 14 to 14.6 volts for bulk charging and to float the battery at 13.8 volts. If you recharge the battery below that range, you’ll have less than 100% charge in the battery - it will be at a partial state of charge. All that means is you’ll need to recharge it again sooner than you otherwise would. But you’re not harming the battery in any way by coming in lower than our recommended range - you’re only cutting into the capacity you’ll have from that charge. If you go over the 14.6-volt limit, our battery monitoring system - or BMS - will sense the over-voltage and disconnect from the battery. That’s it! The only thing that will happen is that the BMS will do what it is designed to do and protect your battery.
What are regen currents and why are they important?
Regenerative currents are currents that are provided to the battery like a charge current during breaking and/or for speed control. InSight batteries are unlike other lithium batteries in that they have the ability to manage these regen currents when they occur. InSight batteries are built with intuitive software to manage this, avoiding disconnects that occur in these scenarios.
What is the available range with InSight batteries?
1 InSight 48V Battery = 12 - 17 miles per charge, 2 InSight 48V Batteries = 24 - 34 miles per charge, 3 InSight 48V Batteries = 36 - 51 miles per charge, 4 InSight 48V Batteries = 48 - 70 miles per charge, 5 InSight 48V Batteries = 60 - 85 miles per charge, 6 InSight 48V Batteries = 72 - 102 miles per charge
Why do I have to use battery spacers in empty slots?
We recommend using our Battery Spacers to fill the empty battery spots so you can use the existing battery hold-down that comes in your vehicle. If you do not use our Battery Spacers, you must take precautions to ensure your InSight batteries are securely held down. Our spacer batteries can be purchased on our website.
How does regenerative braking work for golf carts?
Let’s first start with some basics about your golf cart motor. Electric motors are reversible machines, they can function as motors or as generators. In fact, while your motor is operating, it is the generator effect that produces the Counter Electromotive Force (CEMF), which reduces the current in the motor. Without this effect, the currents in the motor would be too large to manage. An additional advantage of the CEMF is that it can be used to send energy back to the source. The typical situation is one of an electric vehicle rolling on a sharp downhill slope and forcing the motor to turn fast enough to engage the regenerative braking, which sends energy to the batteries. If your battery’s BMS isn’t built to handle regen currents, when this occurs your battery will simply disconnect resulting in a sudden stop, which can be concerning. The good news is our InSight batteries feature intuitive software that tells the BMS to manage these regen currents when they occur. This is quite unique in the lithium battery world today, making InSight truly different from other lithium batteries.
