Digtal Voltage Sensing Relay (DVSR) - 12/24VThe Digital Voltage Sensing Relay (DVSR) allows the charging of a second battery bank from any single charging source. When the voltage on the charged bank rises sufficiently, the DVSR engages allowing the 2nd battery bank to charge. When charging stops and voltage falls, the DVSR automatically isolates the battery banks, ensuring that engine start batteries are kept fully charged. Digital circuitry provides superior reliability and extremely low power consumption. Digital enhancements have introduced remote sensing circuitry that allows an optional connection from the ignition switch to provide the same functionality as single sense VSR and zero power consumption when engine is off. Another benefit is a zero stand by current draw when remote sensing circuit is utilized with a storage mode switch fitted (switch in open position).Features: Safely charge two or more independent battery banks from one charge source such as an alternator or battery charger Charges engine starting batteries before combining auxiliary bank for charging Protects start batteries from becoming flattened by domestic loads Isolates electronics from harmful electrical surges from starter motors Simple to install 3 wire connection leaves alternator wiring intact No volt drop vs diode isolators Ignition protected Surface or panel mountable Replaces previous models 710-125A and 710-125A-DS Multi voltage, auto selects between 12 and 24V DC operation Digital circuits provide very low power consumption and enhanced performance Remote status LED output option WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.

Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth CapableFeatures: Protects the battery against excessive discharge and can be used as a system on/off switch The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The on/off input can be used as a system on/off switch.  12/24V auto ranging The Smart BatteryProtect automatically detects system voltage one time only.  Bluetooth: programming made easy When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set. Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual). If required, Bluetooth can be disabled.  A special setting for Li-ion batteries In this mode the BatteryProtect can be controlled by the VE.Bus BMS. Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual. Ultra-low current consumption This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.  Over voltage protection To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V.  Ignition proof No relays but MOSFET switches, and therefore no sparks.  Delayed alarm output The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.  Delayed load disconnect and delayed reconnect The load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage. 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.

Lynx Smart BMS 1000 Battery Management System for Lithium Smart BatteriesThe Lynx Smart BMS is a dedicated Battery Management System (BMS) for the Victron Lithium Battery Smart batteries. These batteries are Lithium Iron Phosphate (LiFePO4) batteries and are available in 12.8 V or 25.6 V in various capacities. They can be connected in series, parallel, and series/parallel so that a battery bank can be built for system voltages of 12V, 24 V, or 48 V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V and up to 102 kWh in a 24 V1) and 48 V1) system.Out of the various available BMSes, the Lynx Smart BMS is the most feature-rich and complete option and integrates seamlessly into the Lynx Distributor system. This model is a 1000 A (M10) version.Built-in 1000 A ContactorThe contactor acts as a secondary safety system to protect the battery in case the primary controls (ATC, ATD, and/or DVCC) fail to disable loads and/or chargers when required and is also suitable as a remote controllable main system switch.Pre-charge CircuitIn addition to the contactor, a built-in pre-charge circuit prevents high inrush currents when connecting a capacitive load such as a MultiPlus/Quattro or other inverter, eliminating the need for external pre-charging.Monitoring and ControlMonitor and control the BMS via Bluetooth using the VictronConnect App or a GX device such as a Cerbo GX and the VRM Portal. A built-in battery monitor that operates similarly as the other Victron Energy battery monitors, provides data such as state of charge, voltage, current, historical data, status info, and more in real-time and with instant readout even without the need to connect to the BMS, allowing diagnostic at a glance.DVCC closed Loop Control as Well as ATC/ATD ContactsCompatible Victron inverters/chargers and solar chargers are automatically controlled via a connected GX device and DVCC. The ATC/ATD contacts can be used to control other chargers and loads that have a remote on/off port.Programmable RelayThe relay can be used either as an alarm relay (combined with the pre-alarm) or to control an alternator via its external regulator (ignition cable). In Alternator ATC mode, the relay will only activate when the contactor is closed. Alternator ATC contact of the alternator opens first and then with a delay of 2 seconds the contactor. These 2 seconds ensure that the alternator is switched off before the battery is disconnected from the system.AUX TerminalThe advantage of the onboard auxiliary power supply (1.1 A @ system voltage) is to provide power to specific loads (i.e. a GX device) after the BMS has shut down the loads in the event of a low cell voltage event. If no charge voltage is detected within 5 minutes, the BMS, including the AUX connection switches off.VE.Can and NMEA 2000 Data CommunicationVE.Can allows for easy connection (standard RJ45 network cable) and communication with a GX device. Since the CANbus protocol is based on NMEA 2000 (and J1939), it is easy to integrate into a marine network and feed a marine MFD with data (requires a VE.Can to NMEA 2000 micro-C male cable).Lynx Distributor Fuse MonitoringRead out the fuse status and receive an alarm in case a fuse is blown. The Lynx Smart BMS monitors up to 4 connected Lynx Distributors and their fuses via VictronConnect or a GX device 1) To reduce the required balancing time, we recommend using as many different batteries in series as possible for the application. 24 V systems are best built using 24 V batteries, and a 48 V system.This System Contains the Following Components: Lynx Distributor with 2 fused paralleled lithium-ion smart batteries. Lynx Smart BMS with BMS, contactor, and battery monitor A second Lynx distributor provides fused connections for inverter/charger(s), loads and chargers (additional modules can be added if more connections are needed) A Cerbo GX (or other GX device) to read out the Lynx Smart BMS and Lynx Distributor data.
