MultiPlus Settings for LiFePO4 2x 200ah Ampere Time Battery Bank

Hello!

I have just purchased all the parts for a Victron branded solar setup on my motorhome.

Im using two Ampere Time 200ah LiFePO4 batteries in paralell for my bank. What should I set the absorption, float and bulk to when I set up my MultiPlus 3000VA 12v inverter?

I've read a few similar posts and they all sound very forign to me. This is my first solar setup.

If you dont mind... please explain to me like im 5.

Hi! I would like to know if everything worked out and if you would have done anything different. I am most likely going to do a similar set up.

Thank you in advance!

Look into the datasheet of the batteries.

my batteries have not arrived in the mail yet. Will the data sheets usually be shipped with them?

Maybe it is available on the website of the manufacturer?!

Cant find the website. Only Amazon pages. Ive emailed them for more info. That's what I get for trying to save some cash on the batteries and going Chinese!

I found a manual for the 200Ah version, charge voltage should be the same but current should be halved.

edit. Seems that’s for the plus version

Charging voltage is also on the Amazon website

thank you! I dont have the 'plus' batteries. But have started searching that same site for the non-plus manuals.

Do you know what the main parameters are that I should be changing on my MultiPlus?
