Charging booster with very good efficiency, charging current continuously adjustable via app

The charging booster is currently being tested during our spring cruise.

So far, it's working perfectly!

I've replaced my lead-acid leisure batteries with three LiFePO4 batteries. The starter battery remains lead-acid.

My charging and power supply setup now consists of:

- 1 x Victron 15A mains charger for the lead-acid battery

- 1 x Victron 30A mains charger for the lithium batteries

- 1 x Victron 15A solar charge controller for the leisure batteries

- 1 x Victron 1212 50 charge booster

- 1 x Ective 300S battery box, 300Ah, approx. 3600W, primarily for mains-powered devices including TV, cool boxes, induction cooktops, Thermomix, contact grill, air fryer, etc.

I'm still working on fine-tuning the settings, because according to the Victron Connect A0, the leisure batteries are usually charged via the 15A charger, which is intended exclusively for the lead-acid starter battery, presumably indirectly. My new charging booster seems to think, even when connected to shore power, that my engine is running and that it should be charging both the starter and house batteries.

What would a skipper's life be without unsolved mysteries...?

an excellent product

An excellent DC/DC charger. I especially love the automatic motor start detection, which greatly simplifies use and allows you to forget about it. Simple and transparent to use, I love it!

Good marine DC-DC charger for LiFePo batteries

Does the job charging a 300Ah LiFePo battery bank from a lead acid starter battery 110A rated alternator. Easy installation and configuration over Bluetooth using Victron app.
Earlier models (ORI121217040) had reported problems with VHF noise.
I did not observe any such problems with this model (ORI121217050).

Technical question

Jessica D. | May 25, 2024

Hello there! My partner and I are currently upgrading our battery/solarsystem on our boat. We have installed 3 lithium batteries (our house batteries), which are connected in parallel and so far only connected via negative wires with our starter liquid acid battery. The system works so far. Now we‘d like to expand the system, so that we can charge the lithium batteries by the starter battery and alternator. I understand, we do this by adding the DC-DC charger; this way we also prevent our alternator from damage. But now we‘d also like to charge our starter battery via our lithium batteries. Which means, we would use the solar energy to charge the starter battery via litium batteries. I read that this should be possible, however, whenever I look up the DC-DC charger, it is always explained the other way around (charging the lithium batteries by using the starter battery or alternator via charger). Could you help me understand if it is possible to use our house battery for charging the starter battery? Thank you in advance and best regards, Jess

Hi Jessica and partner, you placed your question about the reverse charging function here with the VICTRON Orion DC-DC chargers. These Orion devices do not offer a reverse charging function, so you would be forced to use 2 of them: One for the charging path from the lead-acid battery (alternator) to the lithium battery and the second for the charging path back from the li-battery to the lead-acid battery in the event of energy surplus on the lithium side. Perhaps you should take a closer look at the new STERLING Saturn B2B charger series. STERLING Saturn offer everything in one: adaptation of the charging parameters from lead-acid (alternator) to lithium, reverse charging function in the event of an energy surplus on the Li battery side and charging current limitation to protect the alternator from a possible thermal overload. Current limitation can be done by selection of the device (ampere rating) or using the optional BBR remote control (current limitation to 85 or 65%). You will find the STERLING-Saturn devices under our article numbers 33346 to 33350 and the BBR remote control under 33352. Unfortunately, the product description of these STERLING Saturn devices in our online shop has not yet been optimized. You can find precise details on the STERLING website https://sterling-power.com/products/12v-to-12v-120a-dc-to-dc-charger-bb12120?_pos=1&_sid=4f9d96539&_ss=r&variant=43207491780797 I hope all these details will be helpful. Best regards, Wolfgang
