Once the battery is securely installed and electrically connected it will automatically be available for
use. The internal BMS will actively ensure the battery is
protected and operating safely at all times. The battery
requires no user interface or intervention under normal
conditions.
The Slimline lithium battery voltage can be monitored by
installing an external display, such as our remote voltage
monitor shown right.
Note that unlike lead acid batteries, lithium batteries hold their voltage over the cycle, dropping off
only when the battery is ~90% discharged, as indicated in Figure 6 for illustrative purposes.

The Slimline battery voltages below are a useful guide:
1. A normal full battery open circuit voltage (Voc) with no load rests at 13.3V to 13.6V;
2. Depending on the load voltage may dip 0.5V below the Voc;
3. Below 13V Voc the battery is low, and should be charged to promote a long lifespan.
4. Below 12V Voc the battery is close to empty, and should be charged straight away;
5. Low Voltage Disconnect (LVD) is set at ~10.5V.
