Review: Game changer - I got this for my van build. The sun doesn't always shine but the wheels keep a-turning! I would highly recommend this thing if you're built right for it. MAKE SURE YOUR ALTERNATOR CAN HANDLE THE EXTRA LOAD!!!! Aftermarket high output alternators highly recommended. This unit reliably pulls 48 to 50 amp and up to 700 w when it's really cranking. BE SURE YOU HAVE THE RIGHT FUSES AND OVERSIZED WIRE! If you disregard my warnings you stand the real risk of killing your alt and possibly burning yourself to the ground. It's a lot of juice. Handle it with respect. Do your math and your homework. Also keep in mind that a ton of heat is being generated at the charger. Make sure you have plenty of ventilation to dispell the excess heat and I would advise putting a couple cheap thermostat controlled laptop fans on it. They're like 6 dollars. This will help preserve the charger and prevent excessive heat build up in your cabinet. I actually put a large laptop fan in the air intake opening I put on my cabinet and another to exhaust the heat from the box. Otherwise It's very easy to hook up and required nothing special to hook up and fire up. Worth every cent. Just don't wing it , ok? It's not cheap and messing with this stuff without the right information and prep could cost you dearly. Review: Works Great - 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.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Game changer *by C***L on 23 April 2026* I got this for my van build.

Seamless installation, robust connectors and after I ordered and installed the BT-2 hardware, the app provides all the pertinent information in real time.

Cheers! ### ⭐⭐⭐⭐⭐ Smart purchase battery charger and mppt control in one *by E***D on 15 May 2026* I upgraded my solar panel with the shade tech panel. Then found out I needed to upgrade to this 50amp dc/dc charger from my 30 amp This works well and keeps the batteries top off. If I read the instructions correctly it even charges my automotive start battery if it gets run down. ## Frequently Bought Together - Renogy 12V 50A DC to DC Battery Charger with MPPT, On-Board Battery for Gel, AGM, Flooded and Lithium Batteries, Using Multi-Stage Charging, Solar Panel and Alternator - Renogy 500A Battery Monitor with Shunt, High and Low Voltage Programmable Alarm, Range 10V-120V up to 500A, 20ft Shielded Cable, Compatible 12V Lithium Sealed, Gel, Flooded Batteries,Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/377555287-renogy-12v-30a-dc-to-dc-charger-with-mppt-on](https://www.desertcart.tn/products/377555287-renogy-12v-30a-dc-to-dc-charger-with-mppt-on) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-20*
