Add 100A charger

[hwse]

I am looking to add a second 100A charger to my motorhome for bulk charging when dry camping. I have two 460Ah of LFP installed and charge with a Magnum MS2012 charger at about 100A from a 10kw genset. These batteries can take 200A each so and the generator is hardly doing anything at 100A of charge. Any suggestions for a second charger for bulk charging on the genset? All battery wiring is either 2/0 or 3/0.

You know my opinion a couple times now.

I used an IOTA Engineering DLS-55 in my first system before I had a Victron Multiplus inverter/charger. It isn't programmable, which is probably it's worst feature. It produced a safe charge for my LiFePO4 560 Ah bank. I took it out of the system after the Multiplus was installed.

Here is an 90 amp version

Add the IQ4 LiFePO4 module and it will produce a LiFePO4 charge profile.

The Quattro in my new 48 volt system charges at only 35 amps but the charge profile is programmable. The Quattro 12/5000 can charge at 220 amps. Rather than add a second charger, I would replace the Magnum with a Quattro.
