30Ah 48V Lithium Battery InSight GC2


Item #48V030-GC2


RELiON's InSight Series™ 48V lithium iron phosphate (LiFePO4) battery is a GC2 sized drop-in replacement battery that delivers high-quality performance, power, and precision. This 48V 30Ah battery was designed specifically for golf carts, utility vehicles, LSVs, AGVs, and solar power storage.

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 Battery Spacers to fill the empty battery spots so you can use the existing battery hold-downs that come in your vehicle. 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.

    Ask a Question
    • I was trying to replace my 1500 w electric ATV 48v (4x 12v 20ah) acid battery with one of the Relion 48v 30ah battery. Would this be enough power to run my ATV properly? Also, could you please recommend a charger suitable for the relion 48v 30 ah lithium? Thank you

      Thanks for your question regarding the Relion 48V InSight battery.  Four 12V 20Ah batteries, wired in series, is equivalent to one 48V 20Ah battery.  So the 48V 30Ah Insight battery would be a significant improvement in storage capacity.  That being said, more information is needed to know whether the InSight battery is suitable for the application.  For example, what is the maximum current draw of the ATV?  Also, as you mentioned, we need to address how charging of the InSight battery is accomplished.

      Would you be able to email us at and send the exact brand and model of the ATV?  Then we can provide a more specific answer as to the suitability of the application.
