Finaly, after experiments witch SC instead of battery and with powering through battery charging USB port, I have ended with this “desktop” modification of Mojo:
As a solution I used external power supply MEAN WELL GSM36E07-P1J. It’s switching power supply with short circuit, overload and over voltage protection. Output voltage is 7.5 DC and 4.32A rated current -

Fully charged Mojo battery has output voltage approximately 8.2V to 8.3V DC and power voltage that Mojo requires from battery is approximately 7-8.5V DC. Because output voltage of power supply is 7.5V DC, so it’s s in this acceptable range, I can use it directly instead of the battery. It needs only a minute to drill a one small hole into the frame of Mojo and cable with 5.5/2.1mm power socket connected to the battery PH plug (2PIN, 2mm).
Between Mojo and power adapter I have added small external box with electrolytic capacitators. Specifically, block made up of 11 parallelly connected HITANO 10000uF/10V Low ESR capacitators forming 110mF/10V capacity.
The First benefit of this “desktop” modification is that after disconnecting 5V charging power supply the voltage converter used to charge the battery is deactivated and the Mojo stops getting so hot.
The Second is that with this connection we don't have to wait for the SCs, that were previously used to replace the battery, to charge, and the Mojo goes on immediately. The capacitors are connected as filter capacitors to the power supply, so there is no delay in switching on.
The Third, and most important, benefit is the sound improvement created by overall tightening and improved dynamic of sound.
So far, I’m satisfied with this modification, its behavior and improved sound of Mojo.
