Hi all,
Does anyone know what each pin of this Hitachi 5 Ah 18V Li-ion battery does?:
From left to right:
C+ + T V LS - LD
It powers a cordless grinder that wouldn’t switch on. Only the +, -, and LD pins are present on the tool itself.
I’m guessing:
C+: Charge enable?
T: Temp sense?
V: voltage sense
LS: Load sense?
LD: ?
On the battery, LD is equipotential with -.
When I disconnect the LD line in the tool, it works fine, as does the tool’s battery level indicator and the safety feature that stops the tool starting if the switch is on and you click the battery in place.
What does it do? Can I safely leave it out?
