This is a single 3.2V 280Ah LiFePO4 prismatic cell from CATL, one of the world's largest battery makers. It is a raw building block for DIY home energy storage, off-grid solar banks and low-speed EV packs, not a finished battery. The stud terminal version ships with welded threaded studs so busbars and connector plates bolt straight on, avoiding the drilling and adapter hunting that flat factory terminals often require. Buyers rate it highly, and it competes on capacity and brand reputation against cells like EVE and REPT rather than on convenience features.

This is a CATL 3.2V 280Ah lithium iron phosphate (LiFePO4) cell. It is used as a building block for home energy storage, off-grid solar systems and low-speed vehicle battery packs.
This version has welded threaded stud terminals instead of the flat factory terminals. Busbars and connector plates can be bolted on directly, with no drilling or custom adapters. The default stud thread is M6, and other thread sizes are available on request.
The maximum discharge rate is 3C, which is a peak, short-duration rating of roughly 840A. Some CATL 280Ah documentation gives the continuous charge and discharge rating as closer to 1C (280A). The cycle life of about 5,000 cycles comes from the manufacturer's data card, which does not state the test conditions.
