The Quick Cable Rescue LiFePO4 portable power pack is designed to be a safe unit that offers battery/alternator test functionality, providing 600 peak amps and 400 cranking amps consecutively, in five-second intervals. A microprocessor board controls multiple protection features, including overload, reverse polarity, short circuit, overheat, backfeed/backward current, over-charge/discharge, low voltage and low temperature protections. Also, a 1” by 2” LCD screen was added for clear code recognition. If an error occurs, the microprocessor will display the corresponding protection code. The LiFePO4’s clamps and 8 AWG tin-plated cables allow for heavier current flow through both jaws, rated up to 200 degrees C. The Rescue LiFePO4 portable power pack uses a lithium iron phosphate battery.
