Smart Lithium Batteries in series - balancing issue

Hi,


I have 2x Smart Lithium 150Ah batteries in series.

When almost charged, there is a big difference between the batteries voltages (14.33V and 14.17V)
The individual batteries themselves successfully balance their cells.


Anything to be done?
thanks
JT

With series batteries, you have to fully charge each battery before connecting them in series.

That said, there is not much differential between the 2 batteries.

With a few charge/discharge cycles, the batteries will probably match each other.
