Smart Charging Feature
The DC to DC Battery Charger will regulate its output based on the loads connected to your House
Battery Bank. This function is important to maintain the life of your battery banks as some other
battery chargers mistake loads for discharge and continue to keep the batteries in the bulk or
absorption stage for extended periods of time, which will damage the battery bank. The DC to DC
Battery Charger has two methods of load-based regulation to ensure your battery charger
transitions to float stage when it should do so.
House Battery Bank Charging Algorithm (3 stages)
Note: For DMT2430, all the voltage rating on the above graph are doubled
House Battery Bank (CH1) Charging Voltage
DMT1230, DMT1250 Charging Voltage Setting (See Note 1 for DMT2430)
Battery Type Bulk/Absorption Float (Note 2) Equalization
GEL 14.4V 13.7V N.A.
AGM 14.6V 13.6V N.A.
Flooded 14.4V 13.3V 15.5V ( Note 3)
Lithium 13.9-14.6V (0.1V step) 13.5-14.2V (0.1V step) N.A.
Program (Custom Settings) 13.8-14.8V (0.1V step) 13.0-13.8V (0.1V step) N.A.
Note 1: For DMT2430, all the voltage rating on the above chart are doubled.
Note 2: Charger is acting as a power supply with selected constant output voltage and preset maximum output current.
Note 3: Equalization setting can only be used on flooded battery type selection only. See more details on
“Procedure to Equalize
the Flooded Battery
”
F
or Concorde™ branded batteries (Lifeline, Sun Xtender) use flooded setting and consult battery supplier for equalization
recommendations.
Bulk/Absorption, Absorption-Float Stage Current Setting
The Bulk/Absorption (Bulk/Abs) and Absorption-Float (Abs-Float) Stage current settings are based
on the House Battery Bank size. Typically and for maximum lifespan of the sealed and non-sealed
lead acid battery bank, it is recommended the maximum Bulk/Abs (
“h”) current setting should not
be more than 1/5 of its total capacity in Ah (e.g. select 30A or lower when a 150Ah battery bank is
use). For Lithium battery bank, see section
” Lithium House Battery Bank Current Setting”.
DMT1230 (12V House Battery Bank), DMT2430 (24V House Battery Bank)

DMT1250 (12V House Battery Bank)
Battery Bank Size (Min) in Ah 25 50 75 100 125 150 175 200 225 250
Max. Current Setting
(“h”) in A
5 10 15 20 25 30 35 40 45 50
Once the Bulk/Abs current is selected, the Abs-Float Stage (
“L”) current can be selected. It is
recommended to select 1/10 of the Bulk/Abs current as the Abs-Float stage current setting.

Note: The battery will start the full recharge cycle again when the battery terminal voltage drops to 13.3Vdc on DMT1230/DMT1250,
and 26.6Vdc on DMT2430. If a DC load is always ON and connected to the battery bank, a higher Absorption-Float charging current
is recommended
. If in doubt of the “L” setting, use the highest available current setting for battery protection
.
