-Charging current selection jumper:
 Connect this jumper "BOOST", the charging current increases from 100ma to 500ma. Only do this if your battery is larger than 500mAh to avoid explosion.

 Using a solder jumper to short-circuit only allows functionality in the SJ pin unit, it is also possible to change the pad connections for pins D7 and D8 in P0.09 and P0.10. Charging current selection jumper: Connect this jumper "BOOST", the charging current increases from 100ma to 500ma. Only do this if your battery is larger than 500mAh to avoid explosion.
