I use a Blue Smart IP67 12/25 on my boat to charge a 165 Ah AGM spiral cell battery bank.
Unfortunately the charger switches to float mode before the battery is full.
On a motorboat the battery is usually discharged while out at anchor. When driving back to the marina most of the energy is restored by the alternator. So if shore power is plugged in at the marina the Blue Smart charger reaches absorption voltage very quickly and thinks the battery is already full. This results in absorption time to be miscalculated too short.
I would need some advanced settings to modify calculation of absorption time, or at least a way to manually set minimal or fixed absorption time.
