I recently installed MultiPlus 3000 on our boat managing 4 BattleBorn Lithiums.
As I understand from what I have read so far, is that when the lithium battery type is selected, the rebulk offset is set to .2v. So we are floating at 13.6 and rebulk will trigger at 13.4.
The problem seems to be that when we are on the boat while on shore power (and the charger is in float) and using things that create a DC load like the fresh water pump, diesel furnace, electric heads, this offset gets satisfied and triggers a new charge cycle. So we are re-bulking at least once a day, which on a fixed charge profile sends us through the minimum absorption time specified.
Could someone please help me understand:
- Why is this offset so tight?
- Is there a minimum dwell time it needs to see the offset voltage for to trigger the rebulk?
- Can I/should I change this offset? Can I create a new battery profile?
- It just doesn't seem that this is necessary or good to rebulk-reabsorb frequently.
