Renogy 12V 30A DC-DC On-board Battery Charger with MPPT for Gel, AGM, and Lithium Batteries Using Multi-Stage Charging, in RVs, Cars, Boats, Yachts, Recommended to Match with 40A ANL Fuse

Product Information

As an added bonus, DC to DC chargers provide a steady current. Instead of an alternator’s fluctuating current, they will always provide what your battery needs. This reduces wear and tear on your electrical system, noticeably improving the life of your battery.

Allows you to charge your 12V second/auxiliary deep cycle battery on the go, simultaneously from solar and alternator (9-32V) inputs. Provides an advanced 3 stage charging process to produce a safe and comprehensive charge, a must for deep cycle batteries.

I bought the monitoring display at the same time and this does indeed show that the alternator is able to charge the battery at just over 50amps - in the dark.

Please note: If used with a lithium battery and the BMS shuts down the inputs/outputs to the battery (e.g. in an under-voltage condition), this CTEK unit will not 'wake up' the BMS and so will not be able to charge the battery (this is because the CTEK unit needs to see a minimum battery voltage to commence charging). An external charging source (e.g. mains battery charger, solar charger) will need to be used that can supply a 'wake up' voltage to activate the BMS and allow re-charging. Victron has many versions available for 12, 24, and 48 Volts. The smart edition is able to be connected to your phone through Bluetooth so you can manually program it.I also note that it is intended to be on the far side of the starter battery and charge using of the alternator current that the starter battery is also connected to: phase charging profile (Bulk, Boost, and Float) ensures your service battery will be accurately charged at the correct voltage levels to 100%.

The only effect I see is that when using the SC IGN feed the dc-dc will be drawing power all the time the ignition is on.... so at first start and during stop start events.... this may put an extra load onto the starter battery..... especially if using a Lifepo4 as they will draw max current available... A DC2DC battery charger is like a smart charger for your 12V system. It will boost charge into your battery while you’re driving and also acts as an isolator, so that your starter battery doesn’t go flat when you stop for a while. Many of the tools and equipment needed for different charger installations are the same, but the fuse kits will differ depending on the charger you’re planning to install. mislead or deceive customers in relation to the price, value or quality of products, or their place of origin (manufacture) of a product; Experience the reliability and performance of Victron Energy DC-DC Chargers. Victron is a trusted name in the industry, known for their high-quality power solutions. Enerdrive DC-DC ChargersThe car alternator is not made to charge a deeply discharged battery. The alternator might not be capable of delivering such a high current demand. This will lead to increased wear and overheating of the alternator. c) Nothing in these Business Terms excludes your Statutory Rights as a consumer under the ACL.

This powerful, high-quality battery to battery DCDC charger can charge a 12V battery from another 12V battery with its own power source, or from a solar panel using its built-in solar input, at up to 20A. Overloading the alternator by choosing an unsuitable charger can lead to a burnt-out alternator, which can be costly to replace and highly inconvenient on your adventures.. d) GST: If and when applicable, GST payable on our products will be set out in our invoices.
