“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 12,8V 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

Page 17: Battery Banks Consisting Of Different Batteries
Lithium NG 12,8V 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. -

Lithium NG 12,8V battery manual 4.7. Charger settings The recommended charging parameters for the charging sources are: • For 12.8V models: 14.2V absorption voltage, 2 hours absorption time and 13.5V float voltage • For 25.6V models: 28.4V absorption voltage, 2 hours absorption time and 27.0V float voltage •... -
Page 19: Operation
Lithium NG 12,8V battery manual 5. Operation 5.1. Monitoring & Control A BMS is always required to monitor and control the battery. The battery parameters can be read out in different ways: Via Bluetooth with the VictronConnect app VictronConnect Remote (VC-R): This requires a GX device to be connected to a Lynx Smart BMS NG, and the data must be transmitted to the VRM portal. -

Lithium NG 12,8V battery manual 5.1.2. Monitoring the battery via a GX device The battery parameters can also be read out with a GX device via the Remote Console in conjunction with a Lynx Smart BMS NG. The table in the previous section lists the available parameters per connection type. To check the battery parameters, do the following Open the Remote Console, and from the Device List click on the... - Page 21 Lithium NG 12,8V 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 12,8V 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. - Page 23 Lithium NG 12,8V battery manual Page 20 Operation...
