NOTES
1 - The battery temperature detection is a function
of the characteristics of the NTC resistor used
inside the battery pack. Please consult factory.
2 - Different fast charge and trickle charge currents,
and different time out are available on request
(Maximum charge current cannot exceed 1A).
3 - For connector to the battery pack please consult
factory.
