Votronic Duo Battery Tester S

This compact and robust device displays the two voltages of the on-board battery and the starter battery. It clearly displays the most interesting range of battery voltage from deep discharge to maximum charging voltage. The illuminated dot display provides a fairly accurate indication of the battery voltages, as intermediate values are also easy to read due to neighbouring illuminated dots shining with different brightnesses. At the touch of a button, the on-board or starter battery voltage is selected or the display is switched off. When the battery voltage is low, red indicators warn that the battery needs to be recharged. The connection is made by screw terminals on the back of the unit. The Duo-Akku-Tester S is designed as a panel version to match the VOTRONIC modular system and fits in perfectly with other VOTRONIC display panels (uniform height 85 mm). Of course, it is also possible to retrofit a single display in the vehicle. Small front panel dimensions and the particularly small installation depth of only 15 mm allow mounting in almost any position, storage space behind can still be used.
