    “Load disconnect,” a “Charge disconnect,” a "pre-alarm" contact, and a battery monitor. In addition, it can be connected to a GX device and control compatible Victron Energy equipment via DVCC. • In the event of low cell voltage, the BMS will send a “Load disconnect” signal to turn the load(s) off.

  • Page 11: Charging From An Alternator

    Lithium NG 51,2V battery manual 3.4. Charging from an alternator Compared to lead-acid batteries, lithium batteries have a very low internal resistance and accept a much higher charging current. Special care must be taken to avoid overloading the alternator: Ensure the alternator's current rating is at least twice the battery's capacity rating. For example, a 400A alternator can be safely connected to a 200Ah battery.

  • Page 12: Installation

    Lithium NG 51,2V battery manual 4. Installation 4.1. Unpacking and handling the battery Take care when unpacking the battery. Batteries are heavy. Do not lift the battery by its terminals or by its BMS cables. The battery has two carry handles on either side. The weight of the battery can be found in the Technical data [30] chapter.

  • Page 17: Battery Banks Consisting Of Different Batteries

    Lithium NG 51,2V battery manual 4.5.6. Battery banks consisting of different batteries When constructing a battery bank, ideally, all batteries should be of the same capacity, age and model. However, there are situations where this is impossible, such as when capacity needs to be expanded by adding more batteries or when a single battery in a battery bank needs to be replaced.

To check the battery parameters, do the following Open the Remote Console, and from the Device List click on the...
  • Page 21 Lithium NG 51,2V battery manual Some chargers have a bulk voltage setting. If so, set the bulk voltage to the same value as the absorption voltage. Temperature-compensated charging is not required for lithium batteries; Disable temperature compensation or set temperature compensation to 0 mV/°C in your battery chargers.

  • Page 22: Discharging

    Lithium NG 51,2V battery manual 5.2.2. Discharging Even though a BMS is used, there are still a few possible scenarios in which over-discharge can damage the battery. Be sure to observe the following warning. Lithium batteries are expensive and can be damaged due to over-discharge or overcharge. Damage due to over-discharge can occur if small loads (such as alarm systems, relays, standby currents of certain loads, back current drain of battery chargers, or charge regulators) slowly discharge the battery when the system is not in use.
