What is main difference between LTC4013 and LTC4000? (Both are same 60V Buck Charger . I think other specs are also similar)
LTC4013 is mainly made for Lead-acid batteries? and LTC4000 is for Li-Ion?
But in the datesheet LTC4013 also supports Li-Ion and other multi chemistry batteries.
I want to know difference between LTC4013 and LTC 4000? and what would you recommend if I use Li-Ion or LiFepo4 batteries not Lead acid.
(I am going to use 48V battery pack.)
They are not really comparable. It is comparing apples and oranges.
LTC4013 is an all-inclusive charger. LTC4000 is a charge controller which requires an external regulator.
Either will work fine here…
(Using LTC4000 with LTC3845A)
Either will work fine here, it depends on which other features you need. Both can do all of the battery chemistries you listed. LTC4013 is probably the simplest / cheapest solution.
