State of Charge
Bulk : Involves about 80% of the recharge in which the charger current is held constant (in a constant
current charger), and voltage increases. The properly sized charger will give the battery as much current
as it will accept up to charger capacity (25% of battery capacity in Amp hours)
Absorption : Remaining charge equals 20%, approximately. It makes the charger to hold the voltage at
the charger’s absorption voltage (between 14.1 VDC and 14.8 VDC, depending on charger set points)
and decreasing the current until the battery is fully charged.
Float : The charging voltage is reduced to between 13.0 VDC and 13.8 VDC and held constant, while the
current is reduced to less than 1% of battery capacity. This mode can be used to maintain a fully charged
battery indefinitely.
Equalisation : This is essentially a controlled overcharge (the peak voltage the charger) that attains at
the end of
the BULK mode (absorption voltage) an equalisation voltage, but technically it’s not. Higher
capacity wet (flooded) batteries sometimes benefit from this procedure, particularly the physically tall
batteries. The electrolyte in a wet battery can stratify over time, if not cycled occasionally. In equalisation,
the voltage is brought up above typical peak charging voltage well into the gassing stage and maintained
for a fixed (but limited) period. This stirs up the chemistry in the entire battery, “equalising” the strength
of the electrolyte, and knocking off any loose sulfating that may be on the battery plates.
4.13. Setting Up a Lithium Battery
To set up a Lithium
battery click on the “Battery” icon.
What you can do from this page:

Set up your lithium battery.
After installing a lithium battery, check on the communications page
by clicking on “Li BMS” icon to see
if the BMS information is visible. If some information are not displayed correctly on the page as shown in
the figures below, there is a communication error.
What this page displays:

This will only display if you select the Lithium
battery in the battery option.

They type of communion protocol.

Approved batteries.
