1 hour is the minimum value the Maximum Absorption Time can be set too. The only way to get around this is to use Assistants to force the Multi to Float after Bulk is finished for X number of seconds. Programmable Relay: a relay to close based on charge state- Bulk is finished for X number of seconds. Wire this to an Aux input. Use “Two Signal BMS Assistant” to tell the Multi to go to Float whenever the relay closes. Just test the logic to reverse this so the unit does not stay in Float afterwards. Program the same relay to Open based on battery voltage (slightly less than Float voltage).
