I have a tablet with Dead battery. Since I cannot buy new battery in near future, it cross my mind to connect battery bank directly to pcb (solder output from battery bank to battery connectors on PCB).
Battery is 3.7V and I guess that output from battery bak is 5v. Can this be done without any damage?
I dont have any other solution. Battery is charged independety but it drains in less than 5min.
The tablet is working normal when on battery connections apply 3.7v from power switching source.
