RELiON's InSight Series™ 12V lithium iron phosphate (LiFePO4) battery is a GC2 sized drop-in replacement battery that delivers high-quality performance, power, and precision. This 12V 120Ah battery was designed specifically for recreational vehicles and marine applications.

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. 

They’re also scalable, so you can provide increased power and energy (up to 1200Ah). 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.

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, Relion's proprietary software determines and manages regenerative currents – unlike any other battery solution - avoiding unnecessary battery disconnects.
