Anyone have an idea on how to disable it?** A: Yes, the same thing happened to me with my 30A Victron dc-dc on my 2021 Ford Transit starter battery. The answer is to use the 18A victory dc-dc charger. I learned this the hard way. Some cars can't handle that draw. **Q: Would it harm this victron 12-12-18 if I mounted it in a pickup truck engine compartment, connectors at the bottom and air space around it?** A: For good cooling effect, the Oion is designed for vertical mounting only. Other mounting methods may impair cooling and reduce the service life of the product. **Q: Can I connect the input and output ground together?** A: Yes if not trying to isolate like in a boat for galvanic corrosion. If you don't need the isolation feature just purchase the non-isolated model and save a few dollars. If you already own the isolated model and installing in a RV you can ground both to same ground connection. **Q: I'm looking to find a dc-dc charging solution that also accepts solar input. i'd rather have victron vs redarc or ctek?** A: I use two separate devices. Solar is in series so the input ranges up to 100 volts. It’s nice seeing both via Bluetooth. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***H on November 29, 2024* ### ⭐⭐⭐⭐⭐ Review *by M***R on October 19, 2021* ### ⭐⭐⭐⭐⭐ Review *by J***A on February 27, 2026* ## Frequently Bought Together - Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 18 amp 220-Watt - Battery Charger for Dual Battery Systems - Isolated - Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 100V, 30 amp, 12/24-Volt - Victron Energy SmartShunt Battery Monitor (Bluetooth) - Victron Smart Shunt - 6.5V-70V, 500 amp --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/231905882-orion-tr-smart-dc-to-dc-charger-bluetooth-12-12](https://www.desertcart.vn/products/231905882-orion-tr-smart-dc-to-dc-charger-bluetooth-12-12) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-05*
