Take a look at the IOTA Engineering DLS series, the /IQ4 models.
15 - 75 amp supplies, the /IQ4 indicates an internal charge controller
designed for this use. (They are also isolated output, rated for both
series and parallel setups).
I run a pair of DLS-55/IQ4 as station supply and battery bank charger.
_Measured output_ after a station run-time test a few months back was
105amps ~ 13.2VDC, normal float voltage is 13.6
I have a 3rd unit as a spare / general purpose supply and charger.
One thing though, the MAX charge rate of the batterie(s) connected *MUST*
be greater than the supplies limiter.
I have a 110amp output limit, but a normal use charge limit of 200+ amps
to the bank (max safe even high).
Last thing you want is a 45 amps charger connected to a discharged small
batt or gel-cell with a max safe charge current limit of 10 amps...
I would suggest looking at the DLS-15/IQ4
