Renogy DCC50S to charge two 300 ah LiPo4 batteries?

[philos70]

I started with two 100 amp batteries, moved to one 300 amp battery, and the DCC50S worked fine. I did notice the heat on the unit was pushing 150 degrees fahrenheit when charging by alternator and put a fan on the unit when charging by alternator.

I've got another 300 amp battery and am wondering if I will harm either the Renogy unit or the batteries by using the alternator to charge 600 amp, 12 volt batteries?

I figure it is the job of the DCC50S to regulate how much wattage is delivered to the batteries, and that the size of the batteries shouldn't matter. Of course, the spec sheet says the charging limit is 200 amps of battery.

As an aside, I carry an spare alternator.

Any experience using the Renogy unit to charge 600 amps of battery?

That'd be my only concern. You might use a thermal switch to turn on a PC fan or whatever when temps on the DCC get warm. Example (not necessarily a recommendation).
