Samsung Galaxy J2 Battery

For the Samsung Galaxy J2 phone that we chose for a mobile hotspot to have a problem-free and unlimited battery, we have written a new battery instead of its own battery and used the bms of this old battery to provide external power, thus eliminating the need for a battery. You can connect your old battery to the bms by peeling off the protective tapes, cut the battery connection legs from the right and left well and after a good soldering, you can provide external power with a suitable cable. Remember that since the battery is 3.8V, you can operate it by giving a maximum of 4.2V, if you give more than 4.2V, the phone will not turn on.
