WHY DID I GET A RENOGY DC to DC CHARGER?
I went with the basic Renogy 20A DC to DC Charger because it was the least expensive model that met my needs. I setup this deal below if you want a discount.

NOT ADDRESSED IN THE VIDEO:

(1) WHY DID I REMOVE THE GENERATOR? Adding the DC to DC Charger meant I could remove our onboard Onan generator. The generator was simply not used anymore. See how I removed the generator here:    • REMOVE ONAN GENERATOR from RV to CREA...  . Being able to recharge our house batteries from the engine eliminated the need for a generator. Having one less engine to maintain was another benefit. I was also able to repurpose the generator space and add a new storage compartment, including my DC-DC charger and 2000W Pure Sine Inverter.

(2) WHY NOT UPGRADE YOUR ALTERNATOR? I did not want to make engine modifications. Upgrading the alternator to a higher output model is a common upgrade. The ultimate solution is to add a second alternator dedicated to charging your batteries.

(3) HOW MUCH CURRENT CAN LITHIUM BATTERIES TAKE? You should contact your battery manufacturer for guidance. I’ve heard that fifty percent of the total capacity is a good benchmark. I charge mine at a much lower amperage of 10-20 percent of my total battery capacity.
