4.3.3. Set state of charge

In the VictronConnect app, see: Settings > Battery > Battery start synchronized.
When set to ON, the battery monitor will consider itself synchronized when powered up, resulting in a state of charge of 100%.
If set to OFF, the battery monitor will consider itself un-synchronized when powered up, resulting in a state of charge that is
unknown until the first actual synchronization.
For VictronConnect only: The initial state of charge value can also be manually set, by default, this is 100%, and can be set to a
different value if so desired. See: Settings > Battery > State-of-charge.

4.3.4. Set the auxiliary input function

In the VictronConnect app, see: Settings > Misc > Aux input.
This setting sets the function of the auxiliary input, being:
• Starter battery - Voltage monitoring of a second battery.
• Midpoint - Measuring the midpoint of a battery bank.
• Temperature - Measuring battery temperature via an optional temperature sensor.
• None - The auxiliary input is not used.

4.4. Make Lithium settings (if needed)

LiFePO4 (Lithium Iron Phosphate or LFP) is the most used Li-ion battery chemistry. The factory defaults are in general also
applicable to LFP batteries with exception of these settings:
• Tail current.
• Peukert exponent.
• Charge efficiency.
• Discharge floor.
Tail current
In VictronConnect see: Settings > Battery > Tail current.
Some lithium battery chargers stop charging when the current drops below a set threshold. The tail current must be set higher in
this case.
Peukert exponent
In VictronConnect see: Settings > Battery > Peukert exponent.
When subjected to high discharge rates, lithium batteries perform much better than lead-acid batteries. Set the Peukert exponent
at 1.05, unless the battery supplier advises otherwise.
Charge efficiency
In VictronConnect see: Settings > Battery > Charge efficiency factor.
The charge efficiency of lithium batteries is much higher than that of lead-acid batteries. We recommend setting the charge
efficiency at 99%.
Discharge floor
In VictronConnect see: Setting > Battery > Discharge floor
This setting is used in "the time to go" calculation and is set at 50% by default for lead-acid batteries. However, lithium batteries
usually can be discharged significantly deeper than 50%. The discharge floor can be set to a value between 10 and 20%, unless
the battery supplier advises otherwise.
