It is designed especially for caravans and boats. Caravan and boat systems with high-power inverters are often built on a 48 V battery bank, and electric boat motors and some vehicles' battery packs are also in the 36–72 V range. The vehicle's alternator, however, is 12 or 24 V. The BOOST DCDC-2448 bridges this gap: it also charges the high-voltage battery bank while the engine runs. It draws at most 20 A from the input and delivers at most 15 A of charging current to the battery; conversion efficiency is 95%. It has a digital display connection, a 5 m extension cable and advanced protection circuits. Built-in Bluetooth is optional and must be specified when ordering; write to us before you order if you want this option. The unit is made in Türkiye by Havensis. We ship it anywhere in Türkiye and offer optional on-site installation in the Antalya region. | Brand | Havensis | | --- | --- | | Model | BOOST DCDC-2448 | | Input voltage | 12–32 V (12/24 V systems) | | Battery charged | 36/48/60/72 V | | Max. input current | 20 A | | Max. charging current | 15 A | | Conversion efficiency | 95% | | Display | Digital display connection, 5 m extension cable | | Protection | Advanced protection circuits | | Bluetooth | Built-in, optional (specify when ordering) | | Design | Designed especially for caravans and boats | | Dimensions | 162 × 210 × 70 mm | | Origin | Made in Türkiye | Values are taken from the manufacturer's (Havensis) product list.

Applications ## Where is it used? Anywhere you need to charge a 36–72 V battery bank from a vehicle's 12/24 V system. 🚐 ### 48 V caravan systems Fills the 48 V house battery bank from the vehicle's 12/24 V alternator on the road, so energy is ready for high-power inverter loads. ⛵ ### Boats Charges a 36–72 V battery bank, such as an electric boat motor's or the house system's battery, while the engine runs. 🔋 ### High-voltage battery banks Charges series-connected 36, 48, 60 and 72 V battery banks from a 12/24 V source with a single unit. Installation ## How is it connected? The unit is connected between the 12/24 V starter battery and the 36–72 V battery bank. - ⚙️ **Alternator**While the engine runs - 🔋 **Starter battery**12/24 V - ⬆️ **BOOST DC-DC**DCDC-2448 - 🔋 **Battery bank**36–72 V 📟 The digital display connects with a 5 m extension cable, so you can follow the charging from where you can see it. - 1 ### Connect the input Connect the unit's input to the 12/24 V starter battery. The input current can reach 20 A, so choose the cable and fuse accordingly. - 2 ### Connect the output Connect the output to the 36–72 V battery bank with a suitable fuse close to the battery. - 3 ### Place the display Put the digital display where you can see it using the 5 m cable and follow the charging from there. **Installation tips** - Mount the unit close to the batteries in a ventilated, dry place and keep cable runs short. - The current on the input side is much higher than on the output: drawing 20 A at a 12 V input sends about 4–5 A to a 48 V battery. Choose a thick input cable. - Check that your alternator can handle the extra load; for newer vehicles with smart alternators, ask us. - We recommend having an auto electrician install it; send us your system diagram on WhatsApp and we'll check it together.

No. The unit draws at most 20 A from the input; the current going into the battery depends on the input voltage and the battery voltage. Example: at a 24 V input it draws 24 V × 20 A = 480 W; at 95% efficiency about 8–9 A goes into a 48 V battery. At a 12 V input it is about 4–5 A for the same battery. The highest current is reached with a 24 V input and a 36 V battery bank. ### Which batteries is it used with? With 36, 48, 60 and 72 V battery banks. Send us your battery bank's voltage, type and charging values with your order and we'll check compatibility together. ### Which vehicles is it for? Caravans, motorhomes and boats with a 12 or 24 V electrical system; the unit's input accepts 12–32 V. ### Can I connect a solar panel directly? This unit is designed for a battery and alternator input. To charge a 24–72 V battery bank from panels you need an MPPT device: see our BOOST MPPT charge controller. [BOOST MPPT charge controller →](https://www.gespaenerji.com/en/elektrikli-arac-donusum.html) ### Does it have Bluetooth? Built-in Bluetooth is optional and specified when ordering. Write to us before ordering if you want this option. ### Who installs it, and do you ship outside Antalya? We ship anywhere in Türkiye; an auto electrician can do the installation. In the Antalya region we offer optional on-site installation. **Is your house battery 12 or 24 V?** To charge a 12/24 V house battery from the alternator, see our DCDC-1224 battery chargers.
