BlueSmart IP65 charger

Hello. I want to buy a Blue Smart IP65 12V charger to use it with several batteries: AGM, VRLA, LiFePO4 having different capacities from 7Ah to 40 Ah. If I buy the 15A model, can I decrease the charging current from the application?

The 15A model can charge with 15A or 4A.

Thank you. Maybe with a future firmware update will be possible to charge with a lower current too, as for example 7Ah SLA does not like to be charged with 4A. Will be nice to have a single good charger for all.

I don't think this can be changed with FW, I would say this is a HW limitation.

I think there is one circuit for 15A and one for 4A, nothing between. But this is just a guess.
