Hi all,
I have 2 PowerQueen 25.6V 100Ah connected in series. They're being charged with a Victron Smart Solar 150/35 and a Hoymiles Inverter is taking energy from it. Lately, when reaching the absorption phase of charging, my Victron smartshunt has been throwing alarms to inform me the mid-point voltage deviation is too high.
1 Battery is 4 months older than the other, and has some 30 cycles more than the other.
Using a multimeter, I noticed the older battery seems full (with a higher voltage) where the newer on is still charging (lower voltage)
Connections are tight. Cables are short, 6mm PV-cables.
Yesterday, I had both batteries connected in parallel over night as to 'balance' them - to no further avail.
Any course of action here? How else should I / could I balance these batteries?
How can I know if one of the batteries is defect?
What to do to solve the voltage deviation problem?
thanks for you insights!
all the best,
shiny
