Abstract
A removable and short-circuit-avoidable lithium battery module mainly makes use of a protective device mounted between a control circuit and any two cells. Wherein, the protective device includes a base plate and a conductive surface connecting with the cell, an output tab connecting with the control circuit, and a protective unit mounted on the conductive surface and the output tab. Whereby, the conductive surface and the output tab have larger areas to respectively link the cell and the control circuit. While connecting with electricity, the cell and the control circuit would be more accurately connected. Moreover, the protective unit would become disconnected while the cell and the control circuit are fell and collided, so as to prevent the cell and the control circuit from the inaccurate connection and destruction. The present invention also facilitates to swiftly replace the protective device while it is damaged and to contribute a convenient utility.
