Voltage too low
The connected battery's voltage is lower than selected (12.8V / 16V).
The battery is deep discharged OR it does not match the selected voltage.
1. Confirm battery's nominal voltage matches the selected voltage.
If it matches the selected voltage (12.8V / 16V), go to point 2 below.

The program automatically proceeds to STEP3.
3. Release pushbutton.
Immediately following connection to a battery there may be a 1-2
second delay before charging progresses, during which time:
Battery State Of Charge is measured to determine charge requirement
and duration of the State Of Health test in STEP 9. A low battery will be
tested for 12 hours.
safeTº: Ambient temperature is measured to determine safe charge
k
current parameters. Maximum current will be reduced below 0ºC/32°F.
If the temperature is below -20ºC/-4°F no charging will be
allowed, indicated by LED #8 blinking rapidly.
For temperatures above -20°C / -4°F charge LED #3, 4 or 5 will turn
on and charging will proceed.
The battery SAVE mode engages if the battery is less than 50%
charged OR voltage is between 0.5 to 13.1 Volt (16V: 0.5V <> 16.3V)
IMPORTANT: Read the section VERY FLAT NEGLECTED BATTERIES on
the preceding page.
A very flat battery should progress to STEP 7 within 4 hours, unless
damage has been detected, then charging will be suspended and TEST
LED #8 (red) will flash rapidly, indicating the battery may have suffered
permanent damage or a professional assessment is required.
A deep discharged battery may not hold sufficient voltage to power its
own BMS system. The charger will attempt to automatically reset the
BMS during SAVE mode and continue charging. If charging did not
continue, use the MANUAL RESET: place and hold finger on BMS reset
button for 10 or more seconds, until the program continues to STEP 4.
VERY LOW VOLTAGE SAVE : Current starts at 125mA and will
increase to 325mA depending on charge progress. If the voltage did
not rise above 8.8V (16V: 11V) within 2 hours, charging will be
suspended and the TEST LED #8 (red) will flash, indicating the battery
may have suffered permanent damage or a professional assessment is
required.
LOW VOLTAGE SAVE :
Maximum current is set to 2.5A. The battery's charge acceptance is
monitored for unusual behaviour.
TESTING (2 min) - The battery's ability to hold charge is monitored. A
healthy LiFePO
will be suspended and TEST LED #8 (red) will flash rapidly, indicating
the battery may have suffered permanent damage or a professional
assessment is required.
