Victron Energy 24V/100Ah Lithium-Ion Battery
The advantages of a Lithium-ion battery over conventional lead-acid batteries
• High energy density: more energy with less weight;
• High charge currents (shortens the charge period);
• High discharge currents (enabling, for example, electrical cooking on a small battery bank);
• Long battery life (up to six times the battery life of a conventional battery);
• High efficiency between charging and discharging (very little energy loss due to heat development);
• Higher continuous power available.
Lithium-Iron-Phosphate (LiFePO4 or LFP) is the safest of the mainstream Li-ion battery types.The nominal voltage of a LFP cell is 3,2V (lead-acid: 2V/cell). A 25,6V LFP battery consists of 8 cells connected in series.
A complete system consists of:
• One or more 24V 180Ah or 100Ah Lithium-Ion batteries.
• (optional) The Lynx Power In, a modular dc bus bar.
• The Lynx Ion + Shunt is the Battery Management System (BMS) that controls the batteries. It contains a main safety contactor and a shunt.
- There are two models are available: a 350A model and a 600A model. (optional) The Lynx Distributor, a DC distribution system with fuses.• (optional)
- The Ion Control, a digital control panel. • (optional)
- The Color Control GX, a more advanced digital control panel.
The advantages of the Victron Energy Lynx Lithium-ion battery system
The modular system used adds the following advantages:
• The Victron Energy Lithium-Ion Battery System is easy to install due to its modularity. No complicated wiring diagrams are required.
• Detailed information is available on the waterproof Ion Control display.
• The relay in the Lynx-Ion + Shunt provides maximum safety: in case the chargers or loads do not respond to the commands from the Lynx-Ion + Shunt, the main safety relay will open to prevent permanent damage to the batteries.
• For typical marine installations there is an extra small output, so you can still power the bilge pump while disconnecting all other house loads by opening the main relay.
24V 180Ah/100Ah Victron Energy Lithium-Ion BatteriesThe base of the Victron Energy Lithium-Ion Battery System is formed by individual 24V/180Ah Lithium-ion batteries. They have a built-in Cell Management System (BMS) which protects the battery on a cell level. It monitors individual cell voltage and system temperature, and actively balances the individual cells. All measured parameters are sent to the Lynx Ion which monitors the system as a whole.
Lynx Ion + Shunt
The Lynx Ion + Shuntis the BMS. It contains the safety contactor, and controls the cell-balancing, charging and discharging of the system. Also, it keeps track of the State of Charge of the batteries and calculates the Time to Go. It protects the battery pack from both overcharging and depletion.
When an overcharge is imminent, it will signal the charging devices to decrease or stop charging. This is done with the VE.Can bus (NMEA2000) compatible, and also via the two available open/close contacts. Same when the battery is nearing empty, and there is no charging capability available. It will signal big loads to switch off. For both overcharging and depletion, there is a last safety resort, the built-in 350A or 600 A contractor. In case signaling does not stop the imminent overcharge or depletion, it will open the contractor.
VE.Can / NMEA2000 Canbus
- Communication with the outside world is done via the VE.Can protocol.
