FAQ
Can I run this charger from a portable generator?
Yes with a word of caution. Since the output of the battery charger is directly proportional with
the input voltage, we recommend portable generators with automatic voltage regulation. The
Intelli
SUPPLY is calibrated at the factory assuming 120VAC, 60Hz. Deviations from this voltage
will cause deviations in the output voltage and overall performance.
How many batteries can I recharge at one time with the
Intelli
SUPPLY?
This depends on the size of the batteries. All batteries in the bank must be of the same type and
size. In addition, the
Intelli
SUPPLY is expecting the battery bank to be at full charge in ten hours or
less. Therefore the size of the batteries and their depth of discharge will play a role in the answer
here. Given they were all XS Power 16V AGM batteries with a size of 45Ah at 100% discharged,
you can charge up to four in parallel in ten hours.
Calculating external Battery Charging Time
Charging time will depend on the amp-hour capacity of your battery and on how deeply it is
discharged. The following equation calculates an approximate charging time:
Charging Time = CAP x DOD
CC x 80% where:
Charging Time = Battery recharge time in hours
CAP = Battery capacity in amp-hours
DOD = Battery depth of discharge in percent.
A fully discharged battery has 100% DOD.
CC = Charge current. The rated current output of the
charger in amps.
80% = Typical charging efficiency for lead-acid batteries.
example:
An XS Power 16V AGM battery rated at 100 amp-hours is 40% discharged, that is, it has a
DOD = 40%. Charging time with an
Intelli
SUPPLY 15A unit is calculated as follows:
Charging time = 100Ah x 40% = 1.35 hours (3.3 hours)
15A x 80%
