It is compatible with Bosch's cordless 12 V power tools from the tradesman range for stick batteries. The ECP Li-Ion battery pack in stick form is only suitable for tools in the Professional series of the same voltage class. The ECP stick-shaped Li-Ion battery pack (with electronic cell protection) provides power without memory effect or lazy battery effect. ECP enables electronic monitoring of the cells in the battery. This automatically reduces the output power in the device in case of overload, overheating, or deep discharge.
