Votronic LCD Battery Computer 400S + 400A Smartshunt - 1269

Votronic Battery Computer 400S (LCD Remote Display) incl. 400A Measuring Shunt

Effective battery charging for motorhomes, caravans, boats and off-grid solar systems!

How much charge does my leisure battery actually have left? Is the battery really full? Why is energy being drawn from the battery even though the consumers are switched off?

The VOTRONIC LCD Battery Computer S answers these questions to the nearest percentage (%) and ampere-hour (Ah). At the touch of a button, it provides comprehensive information on the current charge status of the battery, the flowing battery currents, and the battery voltage.

The device is constantly in contact with "its battery" and thus registers and evaluates all battery actions. All charging and discharging currents are meticulously counted, and battery size, self-discharge, battery load, etc., are taken into account using programmed characteristic curve fields. Even the smallest leakage currents are detected 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 charge status (the remaining usable capacity, remaining charge) of the leisure 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 12V and 24V battery voltage. Of course, the current battery voltage ("V") and the current battery current ("A") are also available on the display. Discharge currents (consumers) are indicated by a minus sign. Charging currents are also indicated by an easy-to-read "Charge" symbol. Independently of this, there is another display option for the voltage of a second battery, e.g., for monitoring the vehicle's starter battery.
A ready-to-use connection cable connects the display completely to a robust precision measuring resistor (shunt), which is connected directly to the negative terminal of the leisure battery and from which the battery voltages and currents are recorded.

The following values are measured:
 

• Leisure battery voltage
• Starter battery voltage
• Battery current (Charging = "+" ; Discharging = "-")
• Load by consumers
• Battery capacity "Ah" (remaining charge in ampere-hours)
• Battery capacity "%" (remaining charge in percent)
• Switching output (freely programmable)
• Flashing warning display for undervoltage or overvoltage

Can I additionally program the battery computer?

The LCD Battery Computer S has a freely programmable switching output for control, monitoring, and warning purposes, e.g., to automatically switch consumers or issue a warning depending on the charge status of the leisure battery (0-100%). Switching on and off points can be freely and independently set in %, allowing for various switching functions. In addition, these can be manually overridden at any time by pressing a button. Application example: Automatic protection of the battery against harmful deep discharge, consumers are switched off exactly according to the charge status, e.g., at less than 25% charge status.

How is the battery computer connected?

A ready-to-use connection cable connects the LCD display completely to a robust precision measuring resistor (shunt), which is connected directly to the negative terminal of the leisure battery and from which the battery voltages and currents are recorded. This is also where the switching output for connecting signaling devices or powerful switching relays is located.

Can I use a different shunt?

The display is supplied with a suitable measuring shunt. The devices are calibrated to the measuring shunts included in the scope of delivery and cannot be operated in conjunction with other measuring shunts or interchanged!
