Review on 20 Amp Lithium Battery Charger, 12V And 24V Lifepo4 Lead-Acid AGM/Gel/SLA Portable Car Battery Maintainer Trickle Charger Desulfator For Automotive Boat Motorcycle by Reza Shoecraft

Using to top off lifepo4 solar battery. Have used daily for a month. Easy controls, slide switch for amp selection, push button for battery selection. Information screen shows battery voltage, amps charging, temperature, total amp hours. Alligator clips and wires seem to be good quality. First 3 weeks the fan was noisy when first turned on. It would quiet down after about 30 seconds to a minute. Now it always seems to run at a normal sound level. That it the reason for the 4 stars.
