Features

Easy Installation

InSight batteries come in BCI group size GC2/GC8 allowing for easy installation without modifying trays or battery compartments.

Scalable System

InSight batteries offer freedom and flexibility by utilizing parallel connections, so you can scale your system to provide increased power and energy (up to 300Ah) as needed.

Super Smart BMS

The robust Battery Management System features a combined total of 48 charge and discharge MOFSETs that control current flow in and out of the battery, along with multilayer protective devices that prevent over/under voltage, current and temperature conditions. The multilayer protection allows InSight batteries to pass stringent UL safety standards.

Intelligent Cooling

InSight Series® uses a carefully engineered cooling management system to quickly remove heat from inside the battery during conditions of high discharge and recharge currents. This prevents overheating of critical components and extends the life of the battery.

Robust Communication

CANbus connections allow batteries to communicate real-time operating statistics like the voltage, current, state of charge and state of health, making InSight batteries more user friendly. Plus, all batteries feature a sleep and pulse recovery operation mode to conserve power.

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?
How many batteries you use, depends on your individual needs. Depending on the vehicle make, the terrain, the load in the vehicle, and driving style; 2, InSight batteries will provide 24-34 miles and 3 will provide 36-51 miles. For light usage, we suggest using 2 batteries whereas if you use your vehicle to play golf and get around your neighborhood, then you might want to try using 3 batteries. You can always add another battery to your vehicle if you decide you want even more range.
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
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.
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.
