Datasheet: Download
  • Ideal for Indoor / Outdoor use (lowest temperature: -40°F / -40°C).
    • Weatherproof case with wall mount.
    • Weatherproof battery lead & standard battery clip set.
    • 6' AC Lead ending in SAE Connector.
Features:
  • Professional battery charger and high efficiency diagnostic tester for LiFePO4 / LFP batteries.
  • Perfect for charging and seasonal maintenance of a 12.8V-13.2V LiFePO4 / LFP batteries 2-100 Amp-hour.
  • High Efficiency CEC Listed.
  • Battery SAVE mode with BMS reset: starts from 0.5V with continuous monitoring / testing of charge acceptance or bad / shorted cell condition. Unnecessary (and unsafe) charging of a bad battery is prevented.
  • safeT°: Automatic charge rate adjustment to ambient temperature sensed at the charger. Reduced charging below freezing, no charging if temperature is below -20ºC/-4ºF (can damage lithium batteries).
  • Ampmatic: Microprocessor adjusts current to ideal LiFePO4 charge curve to match battery size / condition, for fastest and most complete charge.

With 5 Amps of charge current available OptiMate lithium unique multi step ampmatic™ program recharges and balances cells within the battery quickly and efficiently. This charger's maintenance program delivers current to the vehicle circuitry, protecting and keeping the battery at 100% charge.

How It Works

  1. Pre-qualification Test
    Displays condition of the battery and measures environment temperature; charge program selected based on results.
  2. Low Volts Recovery
    Controlled charging in protection mode controls the charge of sensitive batteries to ensure that an over discharged battery will be correctly and safely recovered.
    (Tests are conducted throughout this stage to determine if the battery has successfully recovered and can be advanced to BULK CHARGE.)
  3. Bulk Charge
    Processor actively adjusts charge current to match battery capacity and condition, achieving a complete charge in the shortest time.
  4. Short-Circuited / Dead Cell Check
    Charge progress is tracked against the ideal LiFePO4 charge curve. Internal damage will be detected at this point and unnecessary charging of the battery is prevented if it cannot be recovered.
  5. Absorption & Equalization
    For 10 minutes, current is delivered in controlled voltage pulses between 14.0 - 14.3V.
    This improves the batteries cell equalization and overall power delivery.
  6. Charge Verification
    If battery has capped at 13.6V after the 10 minute Absorption and equalization period and reveals a less than optimal charge, the program reverts to absorption for an additional 10 minutes.
  7. Voltage Retention Test
    30 minutes of testing is conducted while no charge is delivered to the battery.
    The test results indicate the battery's general state of health.
    (A green (voltage > 12,7V) result extends the test up to 12 hours, to check for excessive self-discharge or higher than expected power loss through the vehicle's electrical system.)
  8. Charge Maintenance
    This stage is a 12 hour maintenance charge cycle consisting of 30 minute float charge periods at a voltage of 13.6V followed by and alternating with a 30 minute -rest- (no charge current) periods.

*Voltage retention test and maintenance charge cycle will repeat 24 hours after the start of the very first test and continue to repeat for as long as the charger remains connected.*

Good charger after about 1 month of use. Lots of indicators for the various states of charging. My new LiFePO4 battery seems to love it.
