Votronic LCD-Batterie-Computer 400S + 400A Smartshunt

Effective battery charging for motorhomes, caravans, boats and self-sufficient solar systems!
How much remaining charge does my on-board battery actually have? Is the battery really full? Why is energy being drawn from the battery despite the consumer being switched off?
The VOTRONIC LCD Battery Computer S answers these questions precisely to the percent (%) and the ampere-hour (Ah). At the touch of a button, it provides comprehensive information about the current charge status of the battery, the flowing battery currents and the voltage level of the battery.
The device is constantly on? Its battery? in contact and thus registers and evaluates all battery actions. All charging and discharging currents are meticulously counted, battery size, self-discharge, battery load etc. are taken into account on the basis of programmed characteristic curves. Even the smallest leakage currents are recorded and registered. The remaining capacity of the battery is then calculated from the measured values ​​and the battery size. The result is the correct display of the state of charge (the remaining capacity, remaining charge) of the on-board battery as a numerical value in ampere-hours (? Ah?) And in percent (?%?) As well as a clear fill level bar, like a fuel gauge.

The LCD battery computer S is suitable for all battery types (acid, gel, AGM, lithium adjustable) with 12 V and 24 V battery voltage. Of course, the current battery voltage (? V?) And the current battery current (? A?) Are also available in the display. Discharge currents (consumers) are marked with a minus sign. Charging currents are also indicated by a clearly legible? Charge? marked. Regardless of this, there is another display option for the voltage of a second battery, e.g. to monitor the vehicle's starter battery.
A ready-to-plug connection cable completely connects the display with a robust precision measuring resistor (shunt), which is connected directly to the negative pole of the on-board battery and on which the voltages and currents of the battery are recorded.
