Charge rate for 3 LiFePO4 batteries

[Kemmer]

I have (3) 48v 200ah LiFePO4 batteries wired to a combiner box. They are connected to a 10kw Megarevo inverter.

My inverter currently has the charge rate set to 25A. My friend has the same set up on a Solark and his is set at 125A.

Is it possible to increase my charge rate or will that damage the batteries? If I wanted to charge each battery at 20A each, would increase the setting to 60A?

I've included the battery specs below:

Thats 600Ah x .2C max as per your specs = 120A max

60A recommended

Its important to have your batteries wired in a balanced manner so they all get an even amount of current.

But it looks like the specs say 20amp max charge current limit 10/20 amps.

Yea, i wonder what the asterix footnote says...

Maybe just a typo in the specs

The other shot shows max charging at .2c for the 200ah.

So in theory, the 120 is split among the 3 batteries? 40a each?

Why do you say 60A recommended?

20 amp per battery. When wired in parallel, the amps split between the 3 batteries. 60 amps would be about 20 amp per battery.

I understand it is split but the spec says .2C which would be 40amps on one battery and then it says 20 amp max charging so which is it.

There should be 3 sets of numbers. One for each ah rating. 0.2C is correct.

No, it says recommended 10A or 20A depending on which battery is being checked.
Max is 110A where it disconnects...

40 or .2C is max, and 20, or .1C is recommended.
