PROCEEDING TO CHARGE
The LED indicators below are sequenced as they may come on through the course of the program.
LED #1 : POWER ON - Confirms AC power supply to the charger.
HIGH and LOW intensity indication: LOW: No battery connected. HIGH: battery connected and
current is being delivered.
LED #2 : REVERSE POLARITY PROTECTION - Lights when the battery connections are
incorrect. The charger is electronically protected so no damage will result, and the output will
remain disabled until the connections are corrected.
BMS RESET PROCEDURE: for batteries with a built-in battery management system (BMS)
that protects against deep discharge, follow this procedure: 1) Disconnect OptiMate Lithium
from mains supply. Wait for LED #1 to go out. 2) Connect OptiMate Lithium to the battery:
RED clamp to POSITIVE (POS, P or +) terminal and BLACK clamp to NEGATIVE (NEG, N or –)
terminal. 3) Reconnect the OptiMate Lithium to mains supply.
A special BMS reset pulse is delivered for a period of one minute. LED #3 flashes as each
reset pulse is delivered.
The BMS has successfully reset when either LED #3 OR LED #4 lights by itself.
BMS not resetting: 1) An advanced battery management system that includes thermal
protection, prevents operation if the battery temperature falls outside of the manufacturer
recommended safe operating temperature range. Check battery manufacturer's
specifications. 2) Battery is connected in reverse polarity. Correct the connections and try
again. 3) The circuit connected to the battery is preventing the pulse from being delivered.
Disconnect or turn off the circuit and try again. 4) The battery's BMS may have suffered
damage. Have the battery professionally assessed.
LED #3 SAVE : This mode engages if the battery was more than 90% discharged / voltage is
below 12.8V. During the SAVE mode the program limits charge current and tests for cell
damage. Charge current is automatically adjusted as charging progresses. A healthy LiFePO 4
battery will progress to CHARGE mode within 4 hours
ERROR: TEST LED #6 flashing - Charging has been suspended as OptiMate has detected the
battery may have suffered permanent damage and a professional assessment is required.
CAUTION: A deep discharged LiFePO
in one or more cells. Higher capacity batteries with multiple cells in parallel (4s2p or more
configeration) may have a good cell paired with bad cell, if so, it will take longer to detect the
bad cell. Such a battery may heat up excessively during charging, confirming there is
