This charger is excellent for charging a 24V 50Ah LiFePO4 battery. at 24V it's slow at 1.5A but seems to work great and is one of the few chargers in this price range with a LiFePO4 setup. This caused the battery to go back to a resting state of 13.0v where it previously only held 12.4v and I thought the battery had burned out due to too many deep discharges. I can't comment on durability as I've only used it once. A dozen times or so, but it seems very valuable. Tip - Connect the charger to the battery first, then plug it in. This is stated in the instructions but in case you don't read them.
