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!

PRODUCT REVIEWS

They are fantastic. Run my upgraded golf cart with an alltrax 500amp controller and high torque motor with no problems.

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.

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

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.
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?
2 InSight 48V Batteries (60Ah) = 20 - 35 miles per charge 3 InSight 48V Batteries (90Ah) = 30 - 50 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.
