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 48V 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.
How do you install InSight 48V 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 need spacer batteries?
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.
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.
