Probably I should only reply for this…

After going through lot of circuit analysis

I connected 12V bulb to discharge battery to recharge it.  Balancing circuit had a issue of mischarged…. so after draining battry 12v bulb for 3 to 4min I removed it and checked via multimeter

Whaola… its reset to zero now the voltage is 8.4 volts  which drives tablet….

People try on your own risk batteries may explode due to shorts be cautious…

Thank you…. ?

Guys I request someone to disconnect the battery (from board) measure the black to red voltage across connector note the voltage

And Black to Yellow (Res) note the resistance and send me…

 

Recommend to test it when battry is below 10%  please do send me awaiting

I have tested cell cell they are working fine.. both batteries…. but there is problem with the protection circuit…. I don’t know how to troubleshoot it.

Yes

Thank you… ?

Yeah the connector is same as you shown above… and the readings as I mentioned before  its showing 3.7volts with both RED to Black Wire on multimeter…. and 6.7k of resistance block and yellow wires….

 

As you said I’m ready to diagnose it… by removing the battery tape and measure the voltage of each battery….

 

And I used to plug it for charging when the windows in ON (I mean booted up) and  charge it to 70 to 90%  and remove cord then shutdown it….

Reason why I did it was if I plug charge when the system is off… the it would never turn on again…

Somehow last time by holding power button when it was charging it booted up on battry. Latter my friend had charged it when it was OFF since then it’s not starting on battry….

 

NoTe: my jumper Ezpad 6s pro came with 128GB of SSD and NO EMMc there is no onboard EMMc storage… I dont know may be this is reason of some Bios settings.

Plz do assist you points ?
