Main Menu (3L-100B, 3L-150-P only)
The main menu provides the following options:

  • Display On/Off button: Tap any part of the display to turn it on if it’s off.
  • Starter battery icon: Displays starter battery voltage.
  • House battery menu: Provides information about the state of charge (SOC) of the house battery (Note: SOC indication may be inaccurate after installation and becomes operational after the first complete charging of the house battery).

After the settings are confirmed, the main menu appears on the display.

The negative current value means that the battery is discharging and a positive value indicates that the battery is charging. In the latter case, the thunderbolt symbol is displayed on the battery icon.

  • To keep V and I values displayed, tap the “Setting” icon and check the phrase “Always show V and I”.
Charging status icon Description
Charging from a source other than the alternator (solar panels, chargers).

---|---

Note: In order to keep the battery from discharging, the display dims after 2 min. After 15 min, it will turn off. To turn the display back on and resume normal use, tap on it.

General protection
The control unit protects the house battery against excessive discharging and overloads. However, it is recommend-ed that the house battery voltage does not fall below 10.5 V and does not exceed 15 V. If the house battery voltage falls below 11.5 V, charge the battery immediately.

Protection alarms (3L-100B, 3L-150-P only)
If the display shows the 0 V value for the house battery, it is probable that the internal battery management system (BMS) intervened to avoid the excessive discharge.

The control unit will allow a deeper discharge than the internal battery management system (BMS) of the house battery:

Discharge current at 20 °C Maximum discharge time
3L-100B 3L-150-P
100 A 55 min
125 A 25 min
150 A 5 min
175 A 2 min
200 A 30 s

When the battery is discharged the internal battery management system (BMS) triggers an alarm.

There are two ways to resolve the issue:

  • Connect an external battery charger.
  • Press the green icon inside the house battery icon . The control unit will connect the battery to the vehicle alternator shortly.

The control unit has an internal sensor that constantly monitors the ambient temperature.

When the ambient temperature is outside the 0 °C … 45 °C range, the system triggers an alarm:

L-20-NDS-Power-and-Control-3-lion-\(5\)

The alarm disappears when the ambient temperature returns to the normal range.

Charging

When charging the battery with an external charger, the following guidelines should be observed:

  • It is recommended to use chargers intended for charging lithium (LiFePO4) batteries. Other type of charger will reduce battery life.
  • The charger must not perform any desulfation action.
  • When using a configurable charger, set the constant current/constant voltage (CC/CV) option with the follow-ing values:
  • Set the end of charge voltage to 14.4 V.
  • Set the recommended maximum charging current for the battery.
  • The maximum charging voltage should not exceed 14.5 V.

When the battery is charged by the alternator, the process is automatically managed by the control unit.

Storing

  • Before storing fully charge the battery with a recommended battery charger for 1 – 2 days.
  • When the battery is not in use, ensure that the battery voltage does not drop below 12.8 V.
  • When storing the battery for a longer time completely recharge it every 30 days to prevent deep discharge and to ensure it is always ready for use.

Disposal

  • Recycling packaging material: Place the packaging material in the appropriate recycling waste bins wher-ever possible.
  • Recycling products with batteries, rechargeable batteries and light sources: Remove any batteries, rechargeable batteries, and light sources before recycling the product. Return defective or used batteries to your retailer or dispose of them at collection points. Do not dispose of any batteries, rechargeable bat-teries, and light sources with general household waste. If you wish to finally dispose of the product, ask your local recycling center or specialist dealer for details about how to do this in accordance with the ap-plicable disposal regulations. The product can be disposed free of charge.
