Looking for Max Bulk Charge Time and Absorb Time settings for BB Li battery
asked
What are all the Absorb Time and Max Bulk charge settings for a Non-Isolated Victron12/12 30a DC/DC Charger with a Battle Born 100Ah
These times are really down to personal preference, and your setup.
Max Bulk time would nominally be: Time to recharge from deepest normal discharge
Absorption time for Lithiums should be an hour or two - there's no sulphation to break up- and set the float voltage to ~100mV below Abs/Bulk voltage. Change from Absorption to float should be on tail current, which depends on the size of your bank, also on any standing dc loads that the charger is also feeding....
