I understand but until it works you may need to use the 12V/2A supply. If you continue without changes it is likely to work as before. Is it that difficult to use the 12V/2A for a couple of days?
If it is a lithium-based battery it should not be necessary to discharge it, only disconnect it and prevent (wrap plastic around the electrical terminals) it from getting in electrical contact with the 12V/2A power supply. NiCd batteries liked deep-cycling, not lithium batteries.
Hi
FF said that its important that you use a "better/stronger" power supply to check your amp. the stronger e.g. 19V/3-4A should avoid the under voltage protection of the amp....these modern chips check the voltage at their power rails-that means if your weak battery voltages goes lower then this threshold the amp shuts down.
please look for a better power supply -then FF/we can help you...

With the 12V supply the TDA7492 amplifier work without problems, correct?
If so, we have to figure out what to do about the batteries.

Yeah work perfectly, i think i short circuit the amp because in one day one wire from the bms was cut out and when I solder it on bms I didn't remove the jack from amp input power
Try to measure the voltage from each of the 4 output lines and to "-" (minus) supply. If the chip is being deactivated, the 4 output lines should have little voltage.
Yes, please check all your connections. Multimeters cost very little and you cannot do DIY-electronics without a multimeter.
