Hi all

 

TL;DR: if your current firmware version supports running it without battery, do not upgrade. 

 

I got some answers from support.

 

Full answers:

 

>In order to protect the MiFi device, current firmware has already limited the device usage without battery, it cannot be powered on when only connected to charger without battery.

>Using it without battery might damage the MiFi device, that's why it is not allowed to use without battery now.

> All the firmware for M7650 V1.1 should have the limitations

 

> Regarding the device hot issue, if it is overheating, please make sure power saving mode is still enabled and try to change the WiFi range to Short to reduce the transmit power, and also make sure it is used in an open and cool environment, avoid direct sunlight etc.
