2G
≈250mA when moving
+ ≈60mA while internal battery charging
LTE-M / NB-IoT
≈50mA when moving
+ ≈60mA while internal battery charging
Intelligent Power Management – Device enters sleep mode when vehicle is inactive to prevent battery drain
Sleep Current – <1mA
Backup Battery:
2G – 1100mAh LiPo internal backup battery pack
LTE-M / NB-IoT – 200mAh LiPo internal backup battery pack
