Open box sale item. This is a customer-returned or ex-display Pylontech RT12100G31 in open packaging. The battery is fully functional and tested — open box condition means the outer packaging has been opened but the unit itself is unused or inspected and returned to stock. Stock is limited and sold as seen.

The Pylontech RT12100G31 is a 12V 100Ah lithium iron phosphate (LiFePO4) battery with a built-in heating element. It is designed for off-grid cabins, shepherd's huts, rural outbuildings, and static 12V systems in cold climates where standard lithium batteries cannot safely charge below freezing.
