    VE.Bus BMS V2 for Victron LiFePO4 Batteries 12-48VDC - Work with All VE.Bus & GX DevicesThe VE.Bus BMS and VE.Bus BMS V2 is Battery Management System (BMS) designed to interface with and protect a single or multiple Victron Lithium Battery 12,8V & 25,6V Smart (LiFePO4 or LFP) in systems that have Victron inverters or inverter/chargers with VE.Bus communication. It monitors and protects the batteries against the over voltage and under voltage of any individual cell, and also over temperature or under temperature conditions.Based on the status of the battery or batteries, the BMS will: Generate a pre-alarm signal to alert of an imminent cell under voltage conditions. Disable inverting in VE.Bus inverters or inverters/chargers via VE.Bus, and disable other loads via the 'Load Disconnect' terminal in the event of a cell under voltage conditions. Disable charging in VE.Bus inverters or inverters/chargers via VE.Bus and disable other chargers via the 'Charge Disconnect' terminal in the event of a cell overvoltage, under-temperature, or over-temperature conditions. The "original" VE.Bus BMS is best used in systems without a GX device The "next generation" VE.Bus BMS V2 has additional features such as: Remote on/off terminals. Ability to disable VE.Direct and VE.Can solar chargers via a GX device. Allowing control of the VE.Bus inverter/charger from multiple devices, like the Digital Multi Control, the VE.Bus Smart dongle and/or a GX device. Auxiliary power input and output terminals that allow a GX device to remain powered in the event of a system shutdown.

    Victron Smart Battery Monitor - BMV-712 - Grey - Bluetooth Capable [BAM030712000R]

    Smart Battery Monitor - BMV-712 - Grey - Bluetooth CapableFeatures: Bluetooth inside With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth being implemented in most other Victron Energy products, wireless communication between products will simplify system installation and enhance performance.  Download the Victron Bluetooth app Use a smartphone or other Bluetooth enabled device to - customize settings, - monitor all important data on single screen, - view historical data, and to - update the software when new features become available.  Easy to install All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to the monitor with a standard RJ12 telephone cable. Included: RJ 12 cable (10 m) and battery cable with fuse (2 m); no other components needed. Also included are a separate front bezel for a square or round display appearance, a securing ring for rear mounting and screws for front mounting.  Midpoint voltage monitoring One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual, section 5.2, for more information. We recommend our Battery Balancer (BMS012201000) to maximize service life of series-connected lead-acid batteries.  Very low current draw from the battery Current consumption: 0,7Ah per month (1mA) @12V and 0,6Ah per month (0,8mA) @ 24V Especially Li-ion batteries have virtually no capacity left when discharged until low voltage shutdown. After shutdown due to low cell voltage, the capacity reserve of a Li-ion battery is approximately 1Ah per 100Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10mA for example may damage a 200Ah battery if the system is left in discharged state during more than 8 days.  Bi-stable alarm relay Prevents increased current draw in case of an alarm.  Other features - Battery voltage, current, power, ampere-hours consumed and state of charge - Remaining time at the current rate of discharge - Programmable visual and audible alarm - Programmable relay, to turn off non critical loads or to run a generator when needed - 500 Amp quick connect shunt and connection kit - Shunt selection capability up to 10.000 Amps - VE.Direct communication port - Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health - Wide input voltage range: 6,5 – 70V - High current measurement resolution: 10 mA (0,01A) Warranty InfoWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.

  • Sale -49% Mastervolt Charge Mate Pro 90 [83309002]

    Mastervolt Charge Mate Pro 90 [83309002]

    Charge Mate Pro 90Current limited electronic charge relay with high efficiency and reverse current protectionA secondary battery onboard requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.The Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the ChargeMaster Pro.A marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.The Charge Mate Pro series consists of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications. The Charge Mate Pro 90 ensures a higher charge current for example when charging Lithium-Ion batteries. It is also perfectly suitable for large automotive alternators up to 180 A and can be used in parallel operation with a 225 Amp alternator to fulfill even higher continuous power demands of your equipment on board.Charge Mate Pro: for controlled charging from a single source.Applications:Leisure and professional marine and mobile applications. An effective solution for high power demand onboard and/or the need for prioritized or current limited charging.Features: Charges two battery banks from a single source. Electronic charge coupling with very low voltage drop. Makes effective dual charging possible. Suitable for all battery types, including Lithium-Ion. Charge current secondary battery limited to 40 or 90 A. High system reliability by prioritizing charging of the main battery. Unidirectional which blocks return current under all circumstances. Prevents power dips in the onboard electrical network. Suitable for all kinds of chargers and alternators. Monitoring with LED status indication. IP65 electronics in a corrosion-resistant casing with aluminum heat sinks. Fast and easy installation.
