As I said, I'm not an electrician, but do know that chargers do their thing by providing DC current a few volts higher than the batteries being charged. The charger shuts down once a certain level of voltage is reached. On my car, the charger I use produces 14 volts and depending on age/condition the 12 volt battery charges until battery is at 12.6-13.6 volts. Don't even know what voltage this charger works at, although when new, battery measured 26.5-27 volts after charger shut off automatically, so probably about 28 volts.
Been using it this way for about 10 months without problems, so the charger's management system is handling things OK.
One thing I liked about the Lithium Titanate battery system is its stability and safety. Also takes high charge rates. Read about it here:
