Jeti Model Max BEC J-MBJETI model MAX BEC J MB 22985464 MAX BEC can be supplied either by NiXX or LiXX cells, recommended is 2 LiXX cells or 5 6 NiXX cells. Input voltage is indicated by four LEDs. If the input voltage is above 7. 0 V, all three green LEDs are ON. While the cells are gradually discharging, particular LEDs go OFF depending on input voltage (lower then 7 V, 6. 7 V, 6. 45 V). If the input voltage is under 6. 5 V, the red LED goes ON indicating that cells are
