Hey guys, new here. Relatively new to 12v setups all together.
Bought an IP65 15ah to charge my 25ah lithium and my 100 AGM.
Having an issue charging the lithium from flat, it automatically goes to absorption mode, I can’t get it to charge in bulk at all.
what settings do I need to change, if any, to achieve this?
thanks in advance
It looks like, the BMS of the Lithium Battery shuts of due to a too high charging current.
Somewhere on the 25Ah Lithium battery (or in its datasheet), you can find the maximum continuous charge current. I think that you exceed that with the 15A charger.
-> Download Victron Connect and connect to Bluetooth and reduce the charge current to 4A.

I have done as you suggest and it still automatically flicked to absorption.
The battery is showing low voltage when I hook it up to my fridge. Haven’t had a chance to hook it up to a multimeter but other digital devices I have are reading low also.
here are the battery specs, maybe you can shed some light on settings I mate need to change?
