Victon Lithium - first charge - results at end of absorption

Hi All

Just charged a bank of 3 lithium 200Ah batteries (in parallel - total 600Ah) - for first time.

Set the charger to be in absorption for 2 hours - as per manual.

See pictures showing BMV and the 3 batteries - these screen shots were taken 2 minutes before end of absorption (2 hours). I was expecting to see all batteries at 14.20 - but they are all below this.

Does this look OK ?

Thanks

Tim

The cell voltages look OK, especially if it's first time you are charging the batteries.

How are the batteries wired in parallel? With or without busbars?
