Smartsolar mppt 75/15 with Lithium P04 battery

I have a Smartsolar mppt 75/15 with Liontron LifeP04 battery 150ah.


Does a choice on the Connect app for lithium meet the following battery data or are more specific settings required?


Nominal capacity 150Ah / 1920Wh

Working voltage range 11.0 .. 14.6 V

Charging characteristics CCCV / IU

End-of-charge voltage 14.4 - 14.6V

Trickle charge 13.5 - 13.8V

Recommended max. Charging current 75A

Max. Charging current 150A

Duration discharge current 150A

Max. Discharge current (≤ 20 sec.) 200A

Integrated BMS battery management system

Hi @fotograaf3000,

the 75/15 has a lithium profile that has a "End-of-charge voltage" / Absorption voltage of 14.2V and a so called float voltage / trickle charge voltage of 13.5V.
This is close to what Liontron recommends.
But you can always change that profile into a custom profile and adapt settings according to your data sheet.
