## Description

Renogy's 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 a starting battery linked to an alternator 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. With RJ45 communication port featured, you can unlock monitoring features exclusively using the BT-2 Bluetooth Module and Renogy DC Home App, control and monitor the device remotely through your phone in real time.

Review: It does what it claims and very well - Other than a issue with a TAX invoice as in they do not supply one a major pain In Australia if you want to claim the unit as a Business expense as is what i wanted to do. The unit is by far the best one i have tested so far. It does not just charge and cut off it also supplies power to the connected devices so as not to run the battery down when the battery is full and the sun is still shinning. So if you don't need to right this off TAX wise i would recommend it. So 5 stars for the Item 1 start for the seller.
Review: Very happy I got this exact model - I researched for probably three months on what DC to DC charger I was gonna get. This one was highly recommended by everyone. As well as offering solar charging and coming from a reputable brand I know I can trust. I’ve been using it for about a month already and it’s worked awesome. I don’t think it’s possible to find a better deal especially for high-quality name and product like this one.

## Questions & Answers

**Q: Solar input is still limited to 25v on these?  No upgrade planned?  So much for connecting a single 450 watt 48v panel.**
A: Another year later the input voltage is, yes, still 25 volt. I was hoping for a 50-75 volt model as well. My space can accommodate 1x 400 watt panel but not 2x 200 watt panels. Bummer.

**Q: what is the maximum current it draws from the alternator?.**
A: The victron device shows 49 amps charge without solar hooked to it . A few 1000 mile trips and its workin great . Keeps the battleborn batterys at 14.4.

**Q: The manual says: "no temperature compensation when charging lithium battery". Why?**
A: Lithium Batteries can be damaged if the temperature is too low (less than 32 degrees) when charging them. So you have to either have a heater (or a heat pad) to keep the batteries above temp, or you have to disconnect the charging circuit when the temperature is going to be below 32 degrees. That statement is just giving you a heads-up so that you are aware of the consequences that could occur

**Q: Can i use this in an rv trailer by connecting the dc side to the output on the trailers converter, instead of an alternator?**
A: Sure you can but won't get a large amount of amps (unless you have a higher amp inverter/Converter) to charge the system.. Just be sure to wire it without a smart alternator which is found on newer cars.

### ⭐⭐⭐⭐⭐ Works Great
*by R***N on 13 December 2023*

Installed in a bus conversion to take advantage of the alternator charging my LiFePo4 batteries when the engine is running and being able to trickle charge the starter batteries while parked. Seamless installation, robust connectors and after I ordered and installed the BT-2 hardware, the app provides all the pertinent information in real time. Time will determine the durability of the device, but it's working great thus far. Cheers!
