This is a generic 21V lithium-ion battery pack rated at 1300mAh, sold as a replacement for cordless power tools that use the 21V platform. It has a shock-resistant plastic housing and a built-in protection chip for overcharge, overcurrent, overpressure and temperature. The capacity is modest: most branded 18V/20V packs run 2.0Ah to 5.0Ah, so this suits light, short jobs rather than heavy all-day use. The main question is compatibility, since the connector and latch must match your tool's battery system.
