a new (1 cycle) 12V 100 Ah LiFePo4 with bluetooth connection which will deliver power to the air heater of my Van. Was only used for a about 20 hours (2 Amps) for testing.
A Victron Blue Smart 12/25 was used in October to fully charge this battery.
Now after the tests (38% remaining) I tryed to charge the battery but the Victron Blue Smart 12/25 jumps imidiatelly to Absorption charging with 14,20V with 0,0 A. Battery and charger are about 18 degree celcious.
The settings are correct and I restart the charging several times.
I can charge the battery with another normal charger.
Any ideas why this High End equipment is not working?
Thanks a lot
