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...?
