the most efficient rate of charge current for the connected battery, according to its state of charge, state of
health, and electrical storage (Ah) capacity. The delivered current may be anywhere from 2.5A to 9.5A.
VERY FLAT NEGLECTED BATTERIES: Pay particularly close attention to the following A LiFePO
left deep-discharged for an extended period may develop permanent damage in one or more cells. Such
batteries may heat up excessively during charging. During the SAVE mode the program limits charge current
if the voltage is below nomimal (12.8V / 16V) and the program should detect obvious cell damage and will
automatically suspend charging, but the higher the cell count in parallel the more difficult it is to detect a bad
cell. ALWAYS monitor the battery temperature during the first hour, then hourly there-after. If at any time
the battery is uncomfortably hot to touch or you notice any unusual signs, DISCONNECT THE CHARGER
IMMEDIATELY.

are corrected.
BMS RESET:

system (BMS) that protects against deep discharge.
IMPORTANT! Before proceeding, confirm the battery is connected
correctly: Read the section on the previous page: CONNECTING
CHARGER TO THE BATTERY.
Press the BMS RESET pushbutton for at least 3 seconds until LED
#3 flashes every second as a special BMS reset pulse is delivered.
When the OptiMate Lithium senses the battery BMS has reset the
reset pulses will automatically discontinue and the program will
continue to STEP 5. Remove finger from pushbutton.
BMS not resetting: LED #3 lights briefly and then turns off: A deep
discharged battery may not hold sufficient voltage to power its own
BMS system. Use the MANUAL RESET: place and hold finger on BMS reset
button for 10 or more seconds, until the program continues to STEP 4.
BMS not resetting: LED #8 flashes/blinks.
1) Battery is connected in reverse polarity. Correct the connections
and try again. 2) The system powered by the battery is preventing
the pulse from being delivered. Disconnect or turn off the system
and try again. 3) The battery's BMS or the battery itself may have
suffered damage. Have the battery professionally assessed.
More: 4) An advanced battery management system may include
thermal protection that prevents reset if the battery temperature
falls outside of the manufacturer recommended safe operating
temperature range. Check battery manufacturer's specifications.
