Aircraft battery charger TM-275 v2

This Optimate Plug in the Wall Lithium charger will quickly charge your battery at 9.5 amps, maintain it at the optimal voltage, and can be used as a power source of 5 continuous amps! For example, you can use it as power supply while programming your aircraft EFIS so you are not draining your battery while you work. Features: CHARGER MAINTAINER POWER SUPPLY (press TUNE Button) What’s included: 1 x TM-275 v2 charger/maintainer/power supply 1 x battery alligator clips 1 x waterproof quick connect lead with ringlets and SAE connector High efficiency diagnostic charger and tester for LiFePO4 / LFP batteries. Perfect for charging of a high performance 12.8V-13.2V LiFePO4 / LFP battery sized from 2.5 to 120 Amp-hour. Special features: * TUNE mode delivers stable power for vehicle system reprogramming, show room vehicle demo or retaining memorized 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. * safeTº : 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. SAVE : Low Volt Start of 0.5V + 3-step low volt SAVE and TEST
