On my boat is installed Orion-Tr Smart 12/12-18 (220W) Isolated DC-DC charger ORI121222120.
It is used to charge the Lifepo4 battery. The outboard motor has a 35 amp generator. I bought an 18 amp charger to limit the load on the generator. I watch the charging current with my battery meter. When charging, the current is not limited to 18 amps, and can exceed 25 amps.
How can I fix the charging current limit ?
