Renogy's DCC50S DC to DC MPPT on-board Battery Charger is designed to give you options! This multi-stage, multi-input battery charger can charge a service battery from an alternator connected to a starting battery or by utilizing solar panels connected directly to the unit. While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first! It's the smart way to keep yourself fully charged and off-grid longer! And with multi-stage charging and multi-chemistry functionality, Renogy's DC to DC MPPT Charger has you covered whether you're using Flooded, Gel, AGM, or Lithium batteries.
Now you can unlock monitoring features exclusively using the BT-2 Bluetooth Module and Renogy DC Home App!

Review on the 50amp charger,
Awesome product & looking forward to use these products more regularly with my customers . Only one disappointment was the very delayed postage/delivery which I had to put a customer on hold for quite awhile. Apart from that great product looking forward to dealing with you again. Thanks, Harsha Dissa, Director , Yakka ATS Pty Ltd Australia.
50A DC-DC Charger
I upgraded my vehicle to 400 ah Lithium Batteries, when choosing a DC-DC charger I was very interested in being able to maintain my vehicle start battery during long off-grid trips. The Renogy DCC50S came in at a great price and has all the features I was looking for. I have comprehensively tested my new Lithium charging system and am very impressed with the performance of the DCC50S, the only issue I would advise on is to mount the unit where heat can be dissipated, this unit can get very warm when pushing the full 50 amps through it.
