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?
Thanks Seb71
Wired in parallel - all wires same length - all +ve and -ve going to a Victron Lynx Power-In.
Started the multiplus at a very low 10A after installing the VE.Bus BMS Assistant. Then increased to 20A after about 10 minutes - then increased to 30A after another 5 minutes - and left it there (30A) for remainder of charge.
In total the batteries spent about 4 hours in bulk at 30A. Then - 2 hours in absorption.
