The bebob batteries are designed to survive a fall of 1.5m. Nevertheless, if one should crack, the modular concept allows any mechanical part to be replaced. Re-cellable: the bebob batteries arent disposables but durable equipment. When the capacitiy has become insufficient after years of use, batteries can be re-celled easily in our factory for about half the price of a new one.Twist-D-Tap: Only bebob batteries offer the unique bebob Twist-D-Tap. This rainproof socket allows you to plug a D-Tap connector into the battery with your choice of cable trailing from the left or right.
