Hi,
I'm replacing the T-875 battery pack in a golf cart with a 48V Dakota
Lithium LiFePO4 battery. I also ordered their 15A charger to make sure
it would play nice with the builtin BMS. I was very frustrated and
disappointed to discover that this charger puts a continuous 0.12A
drain on the batter

Wouldn't the voltage drop confuse the charger, especially when it gets
to the constant voltage point near end of charge?

The charger won't know about the voltage drop, it would just reduce the
CV voltage by 0.7V or so
The bigger problem is the charger may not start, if there's no voltage
present on it's output.

David,
Why are you unplugging the charger?
Typical Li-Ion chargers or BMS will shut off the power into the
battery when max level is reached.
