6.3.1.3. Battery Source Power Supply Design Guidelines
• The desired nominal output for the power supply is 3.8V
and the maximum voltage allowed is 4.2V, hence a single
3.7V Li-Ion cell battery type is suited for supplying the
power to the Telit GE/GC864-QUAD V2 AND GE864-GPSmodules.
The three cells Ni/Cd or Ni/MH 3,6 V Nom. battery types or
4V PB types MUST NOT BE USED DIRECTLY since their maximum
voltage can rise over the absolute maximum voltage for the
module and damage it.
