Battery Monitor

  • Battery Monitor 100A

    Compact battery monitor, just 124 x 62mm x 23mm!

    Based on the highly successful BM-1 marine battery monitor, the BM-1 Compact is specially designed for applications where space is at a premium.

    Caravans, mobile homes, RV’s, small boats and renewable power installations can all benefit from the BM-1 Compact. It is able to monitor the performance of any 12 Volt lead acid battery system with a capacity of up to 600 AmpHours. The BM-1 Compact is supplied with a precision 100 Amp shunt and prefabricated cables to enable simple DIY installation.

    The unit continually monitors the voltage, the current (charge or discharge) and calculates the state of charge together with the time remaining to charge or discharge the battery.

    This information can lead to more efficient use of the battery enhancing its life and reducing the risk of failure.

    The operation is very simple. One screen displays the voltage, current (charge or discharge) and a bar graph showing the remaining capacity. A flashing alarm is also included to warn if the capacity is getting too low. A second screen shows the remaining time available at the current charge/discharge rate together with the remaining capacity in both analog and digital format.

    The BM-1 Compact consumes a miserly 1.5mA!

    Monitored charging to keep you off grid longer

    The CTEK 20A OFF GRID CHARGING SYSTEM charges your battery bank while you’re driving to stop it going completely flat so you can spend more time off grid. You can charge it from alternator, solar or wind power and, for complete peace of mind, you can see at a glance how much charge you’ve got left and the length of time till your batteries are discharged.

    D250S DUAL The D250S DUAL charger can get its energy from alternators, solar panels and wind power. It separates starter and service battery and maximizes the use of the both without risking that the starter battery is unable to start the engine. SYSTEM MONITOR The System Monitor constantly monitors the voltage and current (charge and discharge) to show you the exact how much charge you have and how many hours you’ve got left before your battery bank is empty.

    The ultimate 12V power system for outdoor vehicles

    Battery to battery charger in a dual battery application

    Enjoy the outdoors for even longer with CTEK’s 100A OFF ROAD CHARGING SYSTEM. It combines the D250S Dual Smart Charger and the SMARTPASS Power Management System for the ultimate 12V power system. Install it in your 4WD, camper trailer or caravan to give you the best performance, power and life from your batteries.

    D250S DUAL The D250S DUAL charger can get its energy from alternators, solar panels and wind power. It separates starter and service battery and maximizes the use of the both without risking that the starter battery is unable to start the engine. SMARTPASS SMARTPASS is a Power Management System with under voltage protection that distributes it to the service batteries or electrical equipment. SMARTPASS separates and prioritized between critical and non-critical consumers to avoid drained service battery. SYSTEM MONITOR The System Monitor constantly monitors the voltage and current (charge and discharge) to show you exactly how much charge you have and how many hours you’ve got left before your battery bank is empty.
