result, and the output will remain disabled until the connections are
corrected.
BMS RESET:
protects against deep discharge. Disconnect the charger from mains supply.
Wait for LED #1a/1b to go out. Reconnect to mains supply. A special BMS
reset pulse is delivered for up to 5 seconds. The program should continue to
STEP 4.
Battery voltage check - OptiMate Lithium automatically activates
if connected battery voltage is at least 0.5 Volt.

TEST LEDs #6/7/8 indicate the battery condition prior to charging. Consult the
table on page 2 to match TEST LED indication to an estimated state of
charge percentage (SOC%).
During the test:
OPTIMIZE minimum charge time is set according to the test result, varying
between 10 minutes for a battery with 80% or higher state of charge to 120
6
minutes
7
for a battery with 40% or less state of charge.

Ambient temperature is measured to determine charge voltage parameters.
TEST
LOW TEMPERATURE WARNING - LED #8 (red) flashing: The temperature
measured at OptiMate Lithium is below -20 degrees Celcius or 4 degrees
Fahernheit, below the safe charging AND discharging zone for LiFePO 4
batteries.
Charging commences after 10 seconds.

to voltage and ambient temperature measured during the test.
VERY LOW VOLTAGE SAVE for batteries between 0.6V and 8.8V :
Current starts at 125mA and will increase to 325mA depending on charge
progress. If the voltage did not rise above 8.8V 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 for batteries between 8.9V and 12.8V (16V):
Maximum current is set to 1.25A. The battery's charge acceptance is
monitored for unusual behaviour.
A healthy LiFePO
otherwise charging will be suspended and TEST LED #8 (red) will flash,
indicating the battery may have suffered permanent damage or a
professional assessment is required.
