Optimate LFP 4s6a Lithium Battery Charger TM-391

This high efficiency diagnostic charger and tester for LiFePO4/LFP batteries is perfect for charging of a high performance 12.8V-13.2V LiFePO4/LFP battery sized from 2.5 to 120 Amp-hour.

Special features include:

• TUNE mode delivers stable power for vehicle system reprogramming, show room vehicle demo or retaining memorised settings when battery cables are disconnected to fit powered accessories or replace the battery.
• BMS reset, pushbutton activated – for batteries with resettable low voltage/deep discharge protection.
• 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.
• safe Tº : 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.
