I have 3 AGM Victron batteries 125Ah each in parallel (375Ah in total), and a lead battery 80Ah for the engine. Which 220V battery charger do you recommend me? I have been looking at IP43 12/30 1+1 and IP43 12/50 1+1. Should the charger have a 10% of the installed amperes? IP43 12/30 1+1 shall suffice and just will charge slower than the 50A version? Other chargers recommended? I’m planning to swap the AGM batteries by LiFePo4 in 3-4 years.
You can limit the maximum charge using the Victron Connect app, so both would work.
LiFePo4: they’ll both work (just set the then correct battery profile), but as these can charge faster than lead-acid… the /50 could be the way to go.
Isn’t the 10% of the battery amps are the safest option in the long run?
That is definitely a good rule. I believe that the manufacturer specification can sometimes in our much higher charge continuously, especially if it lead based battery technologies that are designed for long-term use.
Okay. I saw some posts that suggested 10-30% but I would never go over 15%.
I just ordered a 12/30 Blue Smart battery charger few days ago for my 280Ah lifepo4 battery…so I am staying on a safe side.
And software limiting it can always happen if you decide it has to be lower
Ah okay. I didn’t know that. What’s the difference between the 1 and 3 out 12/30 smart charger? Not much price difference…
Thx.
the 3 output can charge 3 batteries seperatly if the negative is common
Thank you Adam.
