12.8V 100Ah Lithium Iron Phosphate (LiFePO4) Rechargeable Lithium Battery with push button State-of-Charge indicator.

The Pylontech RV12V Series are the newly developed all-purpose lithium iron phosphate battery modules, designed for energy storage applications. With the cutting edge LFP (Lithium Iron Phosphate) cells, embedded BMS (Battery Management System) and mechanical design, Pylontech RV12V Series product provides inherent safety, extremely high reliability and zero maintenance.

The RV12100 is made from 4S4P combination of LiFePO4 Pouch type cells and can be used in any orientation unlike other batteries which may only be used with terminals facing upwards.

A unique feature with this battery is that it is "Array-Aware". That means it knows other batteries are on the bus and only turns on when it senses another battery in parallel or a charger.
