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 fas t charge and trickle charge cur rents,
> 40 °C
and different time out are available on request
(Maximum charge current cannot exc eed 1A).
3 - For connector to the batt ery pack please consult
factory .
