A vast array of different battery types is now available, and the range is constantly growing larger; the problem is that each battery type requires its "own” charging process. We know the solution to this: either a large number of individual chargers or universal chargers, a popular option amongst the modellers. Of course, these universal chargers must be set correctly to suit each battery type and the number of cells, the charging and discharge current, etc. must be defined additionally. It is very easy to lose track of things, forget how to change the settings, or – in the worst case scenario – charge a battery using the wrong settings. Who has not made this mistake: you need to recharge a battery in a hurry, you switch the system on (with the wrong settings), and in a moment your valuable battery is damaged, or perhaps even ruined. The revolutionary BID system from Robbe now offers an ingenious solution to this problem. BID system stands for Battery IDentification system. A small, lightweight BID chip is assigned to each rechargeable battery; this chip stores all relevant data for charging/discharging this battery optimally. The BID chip and the battery are connected to a BID charger for charging or discharging. The BID system informs the charger about the parameters. Press the Start button for initiating the charging/discharging process. No tiresome searching through menus for the set parameters, maximum protection from mishandling, and storing the relevant battery data in the BID chip are the special advantages of the BID system. The BID chip is so small and light (0.5 g) that it can be attached to the battery itself, or fitted inside a shrunk sleeve. Plug connectors at both ends ensure simple handling and reduce the cable weight.
