BID System: The variety of different battery types is constantly increasing, with each type requiring its own charging method. The revolutionary BID system from robbe now offers a brilliant solution to this problem. Each battery is assigned a small, lightweight BID chip that stores all relevant data for optimal charging and discharging of the battery. To charge or discharge, the BID chip and the battery are connected to a BID charger. No more tedious searching for setting parameters in the menu, maximum protection against misuse, and storage of relevant battery data. The BID chip is so small and light (0.5 g) that it can be attached to the battery or shrunk with it.
